# Features removed or planned for replacement starting with Windows 10, version 1803
> Applies to: Windows 10, version 1803
Each release of Windows 10 adds new features and functionality; we also occasionally remove features and functionality, usually because we've added a better option. Here are the details about the features and functionalities that we removed in Windows 10, version 1803 (also called Windows 10 April 2018 Update).
> [!TIP]
> - You can get early access to Windows 10 builds by joining the [Windows Insider program](https://insider.windows.com) - this is a great way to test feature changes.
> - Have questions about other releases? Check out the information for [Windows 10, version 1703](windows-10-creators-update-deprecation.md), and [Windows 10, version 1709](windows-10-fall-creators-deprecation.md).
**The list is subject to change and might not include every affected feature or functionality.**
## Features we removed in this release
We've removed the following features and functionalities from the installed product image in Windows 10, version 1803. Applications or code that depend on these features won't function in this release unless you use an alternate method.
|Feature |Instead you can use...|
|-----------|--------------------
|Groove Music Pass|[We ended the Groove streaming music service and music track sales through the Microsoft Store in 2017](https://support.microsoft.com/help/4046109/groove-music-and-spotify-faq). The Groove app is being updated to reflect this change. You can still use Groove Music to play the music on your PC or to stream music from OneDrive. You can use Spotify or other music services to stream music on Windows 10, or to buy music to own.|
|People - Suggestions will no longer include unsaved contacts for non-Microsoft accounts|Manually save the contact details for people you send mail to or get mail from.|
|Language control in the Control Panel| Use the Settings app to change your language settings.|
|HomeGroup|We are removing [HomeGroup](https://support.microsoft.com/help/17145) but not your ability to share printers, files, and folders.<br><br>When you update to Windows 10, version 1803, you won't see HomeGroup in File Explorer, the Control Panel, or Troubleshoot (**Settings > Update & Security > Troubleshoot**). Any printers, files, and folders that you shared using HomeGroup **will continue to be shared**.<br><br>Instead of using HomeGroup, you can now share printers, files and folders by using features that are built into Windows 10: <br>- [Share your network printer](https://www.bing.com/search?q=share+printer+windows+10) <br>- [Share files in File Explorer](https://support.microsoft.com/help/4027674/windows-10-share-files-in-file-explorer) |
|**Connect to suggested open hotspots** option in Wi-Fi settings |We previously [disabled the **Connect to suggested open hotspots** option](https://privacy.microsoft.com/windows-10-open-wi-fi-hotspots) and are now removing it from the Wi-Fi settings page. You can manually connect to free wireless hotspots with **Network & Internet** settings, from the taskbar or Control Panel, or by using Wi-Fi Settings (for mobile devices).|
|XPS Viewer|We're changing the way you get XPS Viewer. In Windows 10, version 1709 and earlier versions, the app is included in the installation image. If you have XPS Viewer and you update to Windows 10, version 1803, there's no action required. You'll still have XPS Viewer. <br><br>However, if you install Windows 10, version 1803, on a new device (or as a clean installation), you may need to [install XPS Viewer from **Apps and Features** in the Settings app](https://docs.microsoft.com/windows/application-management/add-apps-and-features) or through [Features on Demand](https://docs.microsoft.com/windows-hardware/manufacture/desktop/features-on-demand-v2--capabilities). If you had XPS Viewer in Windows 10, version 1709, but manually removed it before updating, you'll need to manually reinstall it.|
## Features we’re no longer developing
We are no longer actively developing these features and may remove them from a future update. Some features have been replaced with other features or functionality, while others are now available from different sources.
If you have feedback about the proposed replacement of any of these features, you can use the [Feedback Hub app](https://support.microsoft.com/help/4021566/windows-10-send-feedback-to-microsoft-with-feedback-hub-app).
|Feature |Instead you can use...|
|-----------|---------------------|
|[Software Restriction Policies](https://docs.microsoft.com/windows-server/identity/software-restriction-policies/software-restriction-policies) in Group Policy|Instead of using the Software Restriction Policies through Group Policy, you can use [AppLocker](https://docs.microsoft.com/windows/security/threat-protection/applocker/applocker-overview) or [Windows Defender Application Control](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-application-control) to control which apps users can access and what code can run in the kernel.|
|[Offline symbol packages](https://docs.microsoft.com/windows-hardware/drivers/debugger/debugger-download-symbols) (Debug symbol MSIs)|We're no longer making the symbol packages available as a downloadable MSI. Instead, the [Microsoft Symbol Server is moving to be an Azure-based symbol store](https://blogs.msdn.microsoft.com/windbg/2017/10/18/update-on-microsofts-symbol-server/). If you need the Windows symbols, connect to the Microsoft Symbol Server to cache your symbols locally or use a manifest file with SymChk.exe on a computer with internet access.|
|Windows Help Viewer (WinHlp32.exe)|All Windows help information is [available online](https://support.microsoft.com/products/windows?os=windows-10). The Windows Help Viewer is no longer supported in Windows 10. If for any reason you see an error message about "help not supported," possibly when using a non-Microsoft application, read [this support article](https://support.microsoft.com/help/917607/error-opening-help-in-windows-based-programs-feature-not-included-or-h) for additional information and any next steps.|
|Contacts feature in File Explorer|We're no longer developing the Contacts feature or the corresponding [Windows Contacts API](https://msdn.microsoft.com/library/ff800913.aspx). Instead, you can use the People app in Windows 10 to maintain your contacts.|
|Phone Companion|Use the **Phone** page in the Settings app. In Windows 10, version 1709, we added the new **Phone** page to help you sync your mobile phone with your PC. It includes all the Phone Companion features.|
|IPv4/6 Transition Technologies (6to4, ISATAP, and Direct Tunnels)|6to4 has been disabled by default since Windows 10, version 1607 (the Anniversary Update), ISATAP has been disabled by default since Windows 10, version 1703 (the Creators Update), and Direct Tunnels has always been disabled by default. Please use native IPv6 support instead.|
|[Layered Service Providers](https://msdn.microsoft.com/library/windows/desktop/bb513664)|Layered Service Providers have been deprecated since Windows 8 and Windows Server 2012. Use the [Windows Filtering Platform](https://msdn.microsoft.com/library/windows/desktop/aa366510) instead. When you upgrade from an older version of Windows, any layered service providers you're using aren't migrated; you'll need to re-install them after upgrading.|
|Business Scanning, also called Distributed Scan Management (DSM) **(Added 05/03/2018)**|The [Scan Management functionality](https://docs.microsoft.com/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd759124(v=ws.11)) was introduced in Windows 7 and enabled secure scanning and the management of scanners in an enterprise. We're no longer investing in this feature, and there are no devices available that support it.|

|Business Scanning, also called Distributed Scan Management (DSM)|We're removing this secure scanning and scanner management capability - there are no devices that support this feature.|
|[FontSmoothing setting](https://docs.microsoft.com/windows-hardware/customize/desktop/unattend/microsoft-windows-shell-setup-visualeffects-fontsmoothing) in unattend.xml|The FontSmoothing setting let you specify the font antialiasing strategy to use across the system. We've changed Windows 10 to use [ClearType](https://docs.microsoft.com/typography/cleartype/) by default, so we're removing this setting as it is no longer necessary. If you include this setting in the unattend.xml file, it'll be ignored.|
|Hologram app|We've replaced the Hologram app with the [Mixed Reality Viewer](https://support.microsoft.com/help/4041156/windows-10-mixed-reality-help). If you would like to create 3D word art, you can still do that in Paint 3D and view your art in VR or Hololens with the Mixed Reality Viewer.|
|limpet.exe|We're releasing the limpet.exe tool, used to access TPM for Azure connectivity, as open source.|
|Phone Companion|When you update to Windows 10, version 1809, the Phone Companion app will be removed from your PC. Use the **Phone** page in the Settings app to sync your mobile phone with your PC. It includes all the Phone Companion features.|
|Future updates through [Windows Embedded Developer Update](https://docs.microsoft.com/previous-versions/windows/embedded/ff770079\(v=winembedded.60\)) for Windows Embedded Standard 7-SP1 (WES7-SP1) and Windows Embedded Standard 8 (WES8)|We’re no longer publishing new updates to the WEDU server. Instead, you may secure any new updates from the [Microsoft Update Catalog](http://www.catalog.update.microsoft.com/Home.aspx). [Learn how](https://techcommunity.microsoft.com/t5/Windows-Embedded/Change-to-the-Windows-Embedded-Developer-Update/ba-p/285704) to get updates from the catalog.|

|Feature |Instead you can use...|
|-----------|---------------------|
|Companion device dynamic lock APIS|The companion device framework (CDF) APIs enable wearables and other devices to unlock a PC. In Windows 10, version 1709, we introduced [Dynamic Lock](https://docs.microsoft.com/windows/security/identity-protection/hello-for-business/hello-features#dynamic-lock), including an inbox method using Bluetooth to detect whether a user is present and lock or unlock the PC. Because of this, and because third party partners didn't adopt the CDF method, we're no longer developing CDF Dynamic Lock APIs.|
|OneSync service|The OneSync service synchronizes data for the Mail, Calendar, and People apps. We've added a sync engine to the Outlook app that provides the same synchronization.|
|Snipping Tool|The Snipping Tool is an application included in Windows 10 that is used to capture screenshots, either the full screen or a smaller, custom "snip" of the screen. In Windows 10, version 1809, we're [introducing a new universal app, Snip & Sketch](https://blogs.windows.com/windowsexperience/2018/05/03/announcing-windows-10-insider-preview-build-17661/#8xbvP8vMO0lF20AM.97), that provides the same screen snipping abilities, as well as additional features. You can launch Snip & Sketch directly and start a snip from there, or just press WIN + Shift + S. Snip & Sketch can also be launched from the “Screen snip” button in the Action Center. We're no longer developing the Snipping Tool as a separate app but are instead consolidating its functionality into Snip & Sketch.|

## Performance best practices
The following best practices serve as a guideline of query performance best practices and for you to get faster results and be able to run complex queries.
- When trying new queries, always use `limit` to avoid extremely large result sets or use `count` to assess the size of the result set.
- Use time filters first. Ideally, limit your queries to 7 days.
## Optimize query performance
Apply the recommendations to get results faster and avoid timeouts while running complex queries:
- When trying new queries, always use `limit` to avoid extremely large result sets. You can also initially assess the size of the result set using `count`.
- Use time filters first. Ideally, limit your queries to seven days.
- Put filters that are expected to remove most of the data in the beginning of the query, right after the time filter.
- Use the `has` operator over `contains` when looking for full tokens.
- Use looking in specific column rather than using full text search across all columns.
- When joining between two tables, specify the table with fewer rows first.
- When joining between two tables, project only needed columns from both sides of the join.
- Look in a specific column rather than running full text searches across all columns.
- When joining tables, specify the table with fewer rows first.
- `project` only the necessary columns from tables you've joined.

## Query tips and pitfalls
### Using process IDs
Process IDs (PIDs) are recycled in Windows and reused for new processes and therefore can't serve as a unique identifier for a specific process.
To address this issue, Microsoft Defender ATP created the time process. To get a unique identifier for a process on a specific machine, use the process ID together with the process creation time.
### Queries with process IDs
Process IDs (PIDs) are recycled in Windows and reused for new processes. On their own, they can't serve as unique identifiers for specific processes. To get a unique identifier for a process on a specific machine, use the process ID together with the process creation time. When you join or summarize data around processes, include columns for the machine identifier (either `MachineId` or `ComputerName`), the process ID (`ProcessId` or `InitiatingProcessId`), and the process creation time (`ProcessCreationTime` or `InitiatingProcessCreationTime`).
So, when you join data based on a specific process or summarize data for each process, you'll need to use a machine identifier (either `MachineId` or `ComputerName`), a process ID (`ProcessId` or `InitiatingProcessId`) and the process creation time (`ProcessCreationTime` or `InitiatingProcessCreationTime`)
The following example query finds processes that access more than 10 IP addresses over port 445 (SMB), possibly scanning for file shares.
The following example query is created to find processes that access more than 10 IP addresses over port 445 (SMB), possibly scanning for file shares.

@ -59,22 +54,19 @@ NetworkCommunicationEvents
The query summarizes by both `InitiatingProcessId` and `InitiatingProcessCreationTime` so that it looks at a single process, without mixing multiple processes with the same process ID.
### Using command lines
### Queries with command lines
Command lines can vary. When applicable, filter on file names and do fuzzy matching.
There are numerous ways to construct a command line to accomplish a task.
There are numerous ways to construct a command line to accomplish a task. For example, an attacker could reference an image file with or without a path, without a file extension, using environment variables, or with quotes. In addition, the attacker could also change the order of parameters or add multiple quotes and spaces.
For example, a malicious attacker could specify the process image file name without a path, with full path, without the file extension, using environment variables, add quotes, and others. In addition, the attacker can also change the order of some parameters, add multiple quotes or spaces, and much more.
To create more durable queries using command lines, apply the following practices:
To create more durable queries using command lines, we recommended the following guidelines:
- Identify the known processes (such as net.exe, psexec.exe, and others) by matching on the filename fields, instead of filtering on the command line field.
- When querying for command line arguments, don't look for an exact match on multiple unrelated arguments in a certain order. Instead, use regular expressions or use multiple separate contains operators.
- Identify the known processes (such as *net.exe* or *psexec.exe*) by matching on the filename fields, instead of filtering on the command-line field.
- When querying for command-line arguments, don't look for an exact match on multiple unrelated arguments in a certain order. Instead, use regular expressions or use multiple separate contains operators.
- Use case insensitive matches. For example, use `=~`, `in~`, `contains` instead of `==`, `in` or `contains_cs`
- To mitigate DOS command line obfuscation techniques, consider removing quotes, replacing commas with spaces, and replacing multiple consecutive spaces with a single space. This is just the start of handling DOS obfuscation techniques, but it does mitigate the most common ones.
- To mitigate DOS command-line obfuscation techniques, consider removing quotes, replacing commas with spaces, and replacing multiple consecutive spaces with a single space. Note that there are more complex DOS obfuscation techniques that require other approaches, but these can help address the most common ones.

# Query data using Advanced hunting in Microsoft Defender ATP
# Learn the Advanced hunting query language
**Applies to:**
- [Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP)](https://go.microsoft.com/fwlink/p/?linkid=2069559)
>Want to experience Microsoft Defender ATP? [Sign up for a free trial.](https://www.microsoft.com/microsoft-365/windows/microsoft-defender-atp?ocid=docs-wdatp-advancedhunting-abovefoldlink)
Advanced hunting is based on the [Kusto query language](https://docs.microsoft.com/azure/kusto/query/). You can use Kusto syntax and operators to construct queries that locate information in the [schema](advanced-hunting-reference.md) specifically structured for Advanced hunting. To understand these concepts better, run your first query.
To get you started in querying your data, you can use the Basic or Advanced query examples, which have some preloaded queries to help you understand the basic query syntax.
## Try your first query
![Image of Advanced hunting window](images/atp-advanced-hunting.png)
In Microsoft Defender Security Center, go to **Advanced hunting** to run your first query. Use the following example:
## Use advanced hunting to query data
```
// Finds PowerShell execution events that could involve a download.
ProcessCreationEvents
| where EventTime > ago(7d)
| where FileName in ("powershell.exe", "POWERSHELL.EXE", "powershell_ise.exe", "POWERSHELL_ISE.EXE")
| where ProcessCommandLine has "Net.WebClient"
or ProcessCommandLine has "DownloadFile"
or ProcessCommandLine has "Invoke-WebRequest"
or ProcessCommandLine has "Invoke-Shellcode"
or ProcessCommandLine contains "http:"
| project EventTime, ComputerName, InitiatingProcessFileName, FileName, ProcessCommandLine
| top 100 by EventTime'
```
A typical query starts with a table name followed by a series of operators separated by **|**.
In the following example, we start with the table name **ProcessCreationEvents** and add piped elements as needed.
This is how it will look like in Advanced hunting.
![Image of Microsoft Defender ATP Advanced hunting query](images/advanced-hunting-query-example.png)
First, we define a time filter to review only records from the previous seven days.
### Describe the query and specify the table to search
The query starts with a short comment describing what it is for. This helps if you later decide to save your query and share it with others in your organization.
We then add a filter on the _FileName_ to contain only instances of _powershell.exe_.
```
// Finds PowerShell execution events that could involve a download.
ProcessCreationEvents
```
Afterwards, we add a filter on the _ProcessCommandLine_.
The query itself will typically start with a table name followed by a series of elements started by a pipe (`|`). In this example, we start by adding with the table name `ProcessCreationEvents` and add piped elements as needed.
Finally, we project only the columns we're interested in exploring and limit the results to 100 and click **Run query**.
### Set the time range
The first piped element is a time filter scoped within the previous seven days. Keeping the time range as narrow as possible ensures that queries perform well, return manageable results, and don't time out.
You have the option of expanding the screen view so you can focus on your hunting query and related results.
```
| where EventTime > ago(7d)
```
### Search for specific executable files
The time range is immediately followed by a search for files representing the PowerShell application.
### Use operators
The query language is very powerful and has a lot of available operators, some of them are -
```
| where FileName in ("powershell.exe", "POWERSHELL.EXE", "powershell_ise.exe", "POWERSHELL_ISE.EXE")
```
### Search for specific command lines
Afterwards, the query looks for command lines that are typically used with PowerShell to download files.
- **where** - Filter a table to the subset of rows that satisfy a predicate.
- **summarize** - Produce a table that aggregates the content of the input table.
- **join** - Merge the rows of two tables to form a new table by matching values of the specified column(s) from each table.
- **count** - Return the number of records in the input record set.
- **top** - Return the first N records sorted by the specified columns.
- **limit** - Return up to the specified number of rows.
- **project** - Select the columns to include, rename or drop, and insert new computed columns.
- **extend** - Create calculated columns and append them to the result set.
- **makeset** - Return a dynamic (JSON) array of the set of distinct values that Expr takes in the group
- **find** - Find rows that match a predicate across a set of tables.
```
| where ProcessCommandLine has "Net.WebClient"
or ProcessCommandLine has "DownloadFile"
or ProcessCommandLine has "Invoke-WebRequest"
or ProcessCommandLine has "Invoke-Shellcode"
or ProcessCommandLine contains "http:"
```
### Select result columns and length
Now that your query clearly identifies the data you want to locate, you can add elements that define what the results look like. `project` returns specific columns and `top` limits the number of results, making the results well-formatted and reasonably large and easy to process.
To see a live example of these operators, run them as part of the **Get started** section.
```
| project EventTime, ComputerName, InitiatingProcessFileName, FileName, ProcessCommandLine
| top 100 by EventTime'
```
Click **Run query** to see the results. You can expand the screen view so you can focus on your hunting query and the results.
## Learn common query operators for Advanced hunting
Now that you've run your first query and have a general idea of its components, it's time to backtrack a little bit and learn some basics. The Kusto query language used by Advanced hunting supports a range of operators, including the following common ones.
| Operator | Description and usage |
|--|--|
| **where** | Filter a table to the subset of rows that satisfy a predicate. |
| **summarize** | Produce a table that aggregates the content of the input table. |
| **join** | Merge the rows of two tables to form a new table by matching values of the specified column(s) from each table. |
| **count** | Return the number of records in the input record set. |
| **top** | Return the first N records sorted by the specified columns. |
| **limit** | Return up to the specified number of rows. |
| **project** | Select the columns to include, rename or drop, and insert new computed columns. |
| **extend** | Create calculated columns and append them to the result set. |
| **makeset** | Return a dynamic (JSON) array of the set of distinct values that Expr takes in the group. |
| **find** | Find rows that match a predicate across a set of tables. |
To see a live example of these operators, run them from the **Get started** section of the Advanced hunting page.
## Understand data types
Data in Advanced hunting tables are generally classified into the following data types.
| Data type | Description and query implications |
|--|--|
| **datetime** | Data and time information typically representing event timestamps |
| **string** | Character string |
| **bool** | True or false |
| **int** | 32-bit numeric value |
| **long** | 64-bit numeric value |
## Use sample queries
The **Get started** section provides a few simple queries using commonly used operators. Try running these queries and making small modifications to them.
![Image of Advanced hunting window](images/atp-advanced-hunting.png)
>[!NOTE]
>Apart from the basic query samples, you can also access [shared queries](advanced-hunting-shared-queries.md) for specific threat hunting scenarios. Explore the shared queries on the left side of the page or the GitHub query repository.
## Access query language documentation
For more information on the query language and supported operators, see [Query Language](https://docs.microsoft.com/azure/log-analytics/query-language/query-language).
## Use exposed tables in Advanced hunting
The following tables are exposed as part of Advanced hunting:
- **AlertEvents** - Alerts on Microsoft Defender Security Center
- **MachineInfo** - Machine information, including OS information
- **MachineNetworkInfo** - Network properties of machines, including adapters, IP and MAC addresses, as well as connected networks and domains
- **ProcessCreationEvents** - Process creation and related events
- **NetworkCommunicationEvents** - Network connection and related events
- **FileCreationEvents** - File creation, modification, and other file system events
- **RegistryEvents** - Creation and modification of registry entries
- **LogonEvents** - Login and other authentication events
- **ImageLoadEvents** - DLL loading events
- **MiscEvents** - Multiple event types, such as process injection, creation of scheduled tasks, and LSASS access attempts
These tables include data from the last 30 days.
## Use shared queries
Shared queries are prepopulated queries that give you a starting point on running queries on your organization's data. It includes a couple of examples that help demonstrate the query language capabilities.
![Image of shared queries](images/atp-shared-queries.png)
You can save, edit, update, or delete queries.

## Result set capabilities in Advanced hunting
The result set has several capabilities to provide you with effective investigation, including:
- Columns that return entity-related objects, such as Machine name, Machine ID, File name, SHA1, User, IP, and URL, are linked to their entity pages in Microsoft Defender Security Center.
- You can right-click on a cell in the result set and add a filter to your written query. The current filtering options are **include**, **exclude** or **advanced filter**, which provides additional filtering options on the cell value. These cell values are part of the row set.
![Image of Microsoft Defender ATP Advanced hunting result set](images/atp-advanced-hunting-results-filter.png)
## Filter results in Advanced hunting
In Advanced hunting, you can use the advanced filter on the output result set of the query.
The filters provide an overview of the result set where
each column has it's own section and shows the distinct values that appear in the column and their prevalence.
You can refine your query based on the filter by clicking the "+" or "-" buttons on the values that you want to include or exclude and click **Run query**.
![Image of Advanced hunting filter](images/atp-filter-advanced-hunting.png)
The filter selections will resolve as an additional query term and the results will be updated accordingly.

In Microsoft Defender Security Center, go to **Advanced hunting** and select an existing query or create a new query. When using an new query, run the query to identify errors and understand possible results.
> [!NOTE]
> To use a query for a custom detection rule, the query must return the `EventTime`, `MachineId`, and `ReportId` columns in the results. Queries that don’t use the `project` operator to customize results usually return these common columns.
#### Required columns in the query results
To use a query for a custom detection rule, the query must return the `EventTime`, `MachineId`, and `ReportId` columns in the results. Simple queries, such as those that don’t use the `project` or `summarize` operator to customize or aggregate results, typically return these common columns.
There are various ways to ensure more complex queries return these columns. For example, if you prefer to aggregate and count by `MachineId`, you can still return `EventTime` and `ReportId` by getting them from the most recent event involving each machine.
The sample query below counts the number of unique machines (`MachineId`) with antivirus detections and uses this count to find only the machines with more than five detections. To return the latest `EventTime` and the corresponding `ReportId`, it uses the `summarize` operator with the `arg_max` function.

## Get help as you write queries
Take advantage of the following functionality to write queries faster:
- **Autosuggest** — as you write queries, Advanced hunting provides suggestions.
- **Schema reference** — a schema reference that includes the list of tables and their columns is provided next to your working area. For more information, hover over an item. Double-click an item to insert it to the query editor.
## Drilldown from query results
To view more information about entities, such as machines, files, users, IP addresses, and URLs, in your query results, simply click the entity identifier. This opens a detailed profile page for the selected entity in Microsoft Defender Security Center.
## Tweak your queries from the results
Right-click a value in the result set to quickly enhance your query. You can use the options to:
- Explicitly look for the selected value (`==`)
- Exclude the selected value from the query (`!=`)
- Get more advanced operators for adding the value to your query, such as `contains`, `starts with` and `ends with`
![Image of Microsoft Defender ATP Advanced hunting result set](images/atp-advanced-hunting-results-filter.png)
