When Surface Hub is connected to a Wi-Fi network it will use the same channel settings as the Wi-Fi access point for its Miracast access point. For troubleshooting purposes, disconnect Surface Hub from any Wi-Fi networks (but keep Wi-Fi enabled), so you can control the channel used for Miracast. You can manually select the Miracast channel in Settings. You will need to restart Surface Hub after each change. Generally speaking, you will want to use channels that do not show heavy utilization from the network scan.

If Surface Hub and the projecting device are both connected to Wi-Fi but using different access points with different channels, this will force Surface Hub and the projecting device to channel switch while Miracast is connected. This will result in both poor wireless project and poor network performance over Wi-Fi. The channel switching will affect the performance of all wireless traffic, not just wireless projection.
Channel switching will also occur if the projecting device is connected to an Wi-Fi network using a different channel than the channel that Surface Hub uses for Miracast. So, a best practice is to set Surface Hub’s Miracast channel to the same channel as the most commonly used access point.

If there are multiple Wi-Fi networks or access points in the environment, some channel switching is unavoidable. This is best addressed by ensuring all Wi-Fi drivers are up to date.

# Understanding Application Control events
A Windows Defender Application Control (WDAC) policy logs events locally in Windows Event Viewer in either enforced or audit mode. These events are generated under two locations:
1. Event IDs beginning with 30 appear in Applications and Services logs – Microsoft – Windows – CodeIntegrity – Operational
2. Event IDs beginning with 80 appear in Applications and Services logs – Microsoft – Windows – AppLocker – MSI and Script
## Microsoft Windows CodeIntegrity Operational log event IDs
| Event ID | Explanation |
|----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 3076 | Audit executable/dll file |
| 3077 | Block executable/dll file |
| 3089 | Signing information event correlated with either a 3076 or 3077 event. One 3089 event is generated for each signature of a file. Contains the total number of signatures on a file and an index as to which signature it is.<br>Unsigned files will generate a single 3089 event with TotalSignatureCount 0. Correlated in the “System” portion of the event data under “Correlation ActivityID”. |
| 3099 | Indicates that a policy has been loaded |
## Microsoft Windows Applocker MSI and Script log event IDs
| Event ID | Explanation |
|----------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 8028 | Audit script/MSI file generated by Windows LockDown Policy (WLDP) being called by the scripthosts themselves. Note: there is no WDAC enforcement on 3rd party scripthosts. |
| 8029 | Block script/MSI file |
| 8038 | Signing information event correlated with either a 8028 or 8029 event. One 8038 event is generated for each signature of a script file. Contains the total number of signatures on a script file and an index as to which signature it is. Unsigned script files will generate a single 8038 event with TotalSignatureCount 0. Correlated in the “System” portion of the event data under “Correlation ActivityID”. | |
## Optional Intelligent Security Graph (ISG) or Managed Installer (MI) diagnostic events
If either the ISG or MI is enabled in a WDAC policy, you can optionally choose to enable 3090, 3091, and 3092 events to provide additional diagnostic information.
| Event ID | Explanation |
|----------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 3090 | Allow executable/dll file |
| 3091 | Audit executable/dll file |
| 3092 | Block executable/dll file |
3090, 3091, and 3092 events are generated based on the status code of whether a binary passed the policy, regardless of what reputation it was given or whether it was allowed by a designated MI. The SmartLocker template which appears in the event should indicate why the binary passed/failed. Only one event is generated per binary pass/fail. If both ISG and MI are disabled, 3090, 3091, and 3092 events will not be generated.
### SmartLocker template
Below are the fields which help to diagnose what a 3090, 3091, or 3092 event indicates.
| Name | Explanation |
|-------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| StatusCode | STATUS_SUCCESS indicates a binary passed the active WDAC policies. If so, a 3090 event is generated. If not, a 3091 event is generated if the blocking policy is in audit mode, and a 3092 event is generated if the policy is in enforce mode. |
| ManagedInstallerEnabled | Policy trusts a MI |
| PassesManagedInstaller | File originated from a trusted MI |
| SmartlockerEnabled | Policy trusts the ISG |
| PassesSmartlocker | File had positive reputation |
| AuditEnabled | True if the policy is in audit mode, otherwise it is in enforce mode |
### Enabling ISG and MI diagnostic events
In order to enable 3091 audit events and 3092 block events, you must create a TestFlags regkey with a value of 0x100. You can do so using the following PowerShell command:
```powershell
reg add hklm\system\currentcontrolset\control\ci -v TestFlags -t REG_DWORD -d 0x100
```
In order to enable 3090 allow events, you must create a TestFlags regkey with a value of 0x300. You can do so using the following PowerShell command:
```powershell
reg add hklm\system\currentcontrolset\control\ci -v TestFlags -t REG_DWORD -d 0x300
```

# Signing Windows Defender Application Control policies with SignTool.exe
**Applies to:**
- Windows 10
- Windows Server 2016
Signed WDAC policies give organizations the highest level of malware protection available in Windows 10.
In addition to their enforced policy rules, signed policies cannot be modified or deleted by a user or administrator on the computer.
These policies are designed to prevent administrative tampering and kernel mode exploit access.
With this in mind, it is much more difficult to remove signed WDAC policies.
Before you sign and deploy a signed WDAC policy, we recommend that you [audit the policy](audit-windows-defender-application-control-policies.md) to discover any blocked applications that should be allowed to run.
Signing WDAC policies by using an on-premises CA-generated certificate or a purchased code signing certificate is straightforward.
If you do not currently have a code signing certificate exported in .pfx format (containing private keys, extensions, and root certificates), see [Optional: Create a code signing certificate for Windows Defender Application Control](create-code-signing-cert-for-windows-defender-application-control.md) to create one with your on-premises CA.
Before signing WDAC policies for the first time, be sure to enable rule options 9 (“Advanced Boot Options Menu”) and 10 (“Boot Audit on Failure”) to leave troubleshooting options available to administrators. To ensure that a rule option is enabled, you can run a command such as `Set-RuleOption -FilePath <PathAndFilename> -Option 9` even if you're not sure whether the option is already enabled—if so, the command has no effect. When validated and ready for enterprise deployment, you can remove these options. For more information about rule options, see [Windows Defender Application Control policy rules](select-types-of-rules-to-create.md).
To sign a WDAC policy with SignTool.exe, you need the following components:
- SignTool.exe, found in the Windows SDK (Windows 7 or later)
- The binary format of the WDAC policy that you generated in the [Create a Windows Defender Application Control policy from a reference computer](create-initial-default-policy.md) section or another WDAC policy that you have created
- An internal CA code signing certificate or a purchased code signing certificate
If you do not have a code signing certificate, see the [Optional: Create a code signing certificate for Windows Defender Application Control](create-code-signing-cert-for-windows-defender-application-control.md) section for instructions on how to create one. If you use an alternate certificate or WDAC policy, be sure to update the following steps with the appropriate variables and certificate so that the commands will function properly. To sign the existing WDAC policy, copy each of the following commands into an elevated Windows PowerShell session:
1. Initialize the variables that will be used:
`$CIPolicyPath=$env:userprofile+"\Desktop\"`
`$InitialCIPolicy=$CIPolicyPath+"InitialScan.xml"`
`$CIPolicyBin=$CIPolicyPath+"DeviceGuardPolicy.bin"`
> [!NOTE]
> This example uses the WDAC policy that you created in [Create a Windows Defender Application Control policy from a reference computer](create-initial-default-policy.md). If you are signing another policy, be sure to update the **$CIPolicyPath** and **$CIPolicyBin** variables with the correct information.
2. Import the .pfx code signing certificate. Import the code signing certificate that you will use to sign the WDAC policy into the signing user’s personal store on the computer that will be doing the signing. In this example, you use the certificate that was created in [Optional: Create a code signing certificate for Windows Defender Application Control](create-code-signing-cert-for-windows-defender-application-control.md).
3. Export the .cer code signing certificate. After the code signing certificate has been imported, export the .cer version to your desktop. This version will be added to the policy so that it can be updated later.
4. Navigate to your desktop as the working directory:
`cd $env:USERPROFILE\Desktop`
5. Use [Add-SignerRule](https://docs.microsoft.com/powershell/module/configci/add-signerrule) to add an update signer certificate to the WDAC policy:
`Add-SignerRule -FilePath $InitialCIPolicy -CertificatePath <Path to exported .cer certificate> -Kernel -User –Update`
> [!NOTE]
> \<Path to exported .cer certificate> should be the full path to the certificate that you exported in step 3.
Also, adding update signers is crucial to being able to modify or disable this policy in the future.
6. Use [Set-RuleOption](https://docs.microsoft.com/powershell/module/configci/set-ruleoption) to remove the unsigned policy rule option:
`Set-RuleOption -FilePath $InitialCIPolicy -Option 6 -Delete`
7. Use [ConvertFrom-CIPolicy](https://docs.microsoft.com/powershell/module/configci/convertfrom-cipolicy) to convert the policy to binary format:
`ConvertFrom-CIPolicy $InitialCIPolicy $CIPolicyBin`
8. Sign the WDAC policy by using SignTool.exe:

> [!NOTE]
> The *&lt;Path to signtool.exe&gt;* variable should be the full path to the SignTool.exe utility. **ContosoDGSigningCert** is the subject name of the certificate that will be used to sign the WDAC policy. You should import this certificate to your personal certificate store on the computer you use to sign the policy.
9. Validate the signed file. When complete, the commands should output a signed policy file called DeviceGuardPolicy.bin.p7 to your desktop. You can deploy this file the same way you deploy an enforced or non-enforced policy. For information about how to deploy WDAC policies, see [Deploy and manage Windows Defender Application Control with Group Policy](deploy-windows-defender-application-control-policies-using-group-policy.md).

Signed WDAC policies give organizations the highest level of malware protection available in Windows 10.
In addition to their enforced policy rules, signed policies cannot be modified or deleted by a user or administrator on the computer.
These policies are designed to prevent administrative tampering and kernel mode exploit access.
With this in mind, it is much more difficult to remove signed WDAC policies.
Signed WDAC policies give organizations the highest level of malware protection available in Windows 10. In addition to their enforced policy rules, signed policies cannot be modified or deleted by a user or administrator on the computer. These policies are designed to prevent administrative tampering and kernel mode exploit access. With this in mind, it is much more difficult to remove signed WDAC policies. Note that SecureBoot must be enabled in order to restrict users from updating or removing signed WDAC policies.
Before you sign and deploy a signed WDAC policy, we recommend that you [audit the policy](audit-windows-defender-application-control-policies.md) to discover any blocked applications that should be allowed to run.
Signing WDAC policies by using an on-premises CA-generated certificate or a purchased code signing certificate is straightforward.

# Windows Defender Application Control operational guide
**Applies to**
- Windows 10
- Windows Server 2016
After designing and deploying your Windows Defender Application Control (WDAC) policies, this guide covers understanding the effects your policies are having and troubleshooting when they are not behaving as expected. It contains information on where to find events and what they mean, and also querying these events with Microsoft Defender Advanted Threat Protection (MDATP) Advanced Hunting feature.
## WDAC Events Overview
WDAC generates and logs events when a policy is loaded as well as when a binary attempts to execute and is blocked. These events include information that identifies the policy and gives more details about the block. Generally, WDAC does not generate events when a binary is allowed; however, there is the option to enable allow events when Managed Installer and/or the Intelligent Security Graph (ISG) is configured.
WDAC events are generated under two locations:
1. Applications and Services logs – Microsoft – Windows – CodeIntegrity – Operational
2. Applications and Services logs – Microsoft – Windows – AppLocker – MSI and Script
