### Windows Update for Business
[Windows Update for Business](./update/waas-manage-updates-wufb.md) enhancements in this release include:
- Intune console updates: target version is now available allowing you to specify which version of Windows 10 you want devices to move to. Additionally, this capability enables you to keep devices on their current version until they reach end of service. Check it out in Intune, also available as a Group Policy and Configuration Service Provider (CSP) policy.
- Validation improvements: To ensure devices and end users stay productive and protected, Microsoft uses safeguard holds to block devices from updating when there are known issues that would impact that device. Also, to better enable IT administrators to validate on the latest release, we've created a new policy that enables admins to opt devices out of the built-in safeguard holds.

- [**Automatic Restart Sign-on (ARSO)**](/windows-server/identity/ad-ds/manage/component-updates/winlogon-automatic-restart-sign-on--arso-): Windows automatically signs in as the user and locks their device in order to complete the update. This automatic sign-on ensures that when the user returns and unlocks the device, the update is completed.
- [**Windows Update for Business**](https://techcommunity.microsoft.com/t5/Windows-IT-Pro-Blog/Windows-Update-for-Business-and-the-retirement-of-SAC-T/ba-p/339523): There's now a single, common start date for phased deployments (no more SAC-T designation). In addition, there's a new notification and reboot scheduling experience for end users, the ability to enforce update installation and reboot deadlines, and the ability to provide end user control over reboots for a specific time period.

In addition, there will be a new notification and reboot scheduling experience for end users, the ability to enforce update installation and reboot deadlines, and the ability to provide end user control over reboots for a specific time period.
- **Update rollback improvements**: You can now automatically recover from startup failures by removing updates if the startup failure was introduced after the installation of recent driver or quality updates. When a device is unable to start up properly after the recent installation of Quality of driver updates, Windows will now automatically uninstall the updates to get the device back up and running normally.
- **Pause updates**: We've extended the ability to pause updates for both feature and monthly updates. This extension ability is for all editions of Windows 10, including Home. You can pause both feature and monthly updates for up to 35 days (seven days at a time, up to five times). Once the 35-day pause period is reached, you'll need to update your device before pausing again.
- **Improved update notifications**: When there's an update requiring you to restart your device, you'll see a colored dot on the Power button in the Start menu and on the Windows icon in your taskbar.
- **Intelligent active hours**: To further enhance active hours, users now can let Windows Update intelligently adjust active hours based on their device-specific usage patterns. You must enable the intelligent active hours feature for the system to predict device-specific usage patterns.
- **Improved update orchestration to improve system responsiveness**: This feature will improve system performance by intelligently coordinating Windows updates and Microsoft Store updates, so they occur when users are away from their devices to minimize disruptions.
Microsoft previously announced that we're [extending support](https://www.microsoft.com/microsoft-365/blog/2018/09/06/helping-customers-shift-to-a-modern-desktop) for Windows 10 Enterprise and Windows 10 Education editions to 30 months from the version release date. These editions include all past versions and future versions that are targeted for release in September (versions ending in 09, ex: 1809). Future releases that are targeted for release in March (versions ending in 03, ex: 1903) will continue to be supported for 18 months from their release date. All releases of Windows 10 Home, Windows 10 Pro, and Microsoft 365 Apps for enterprise will continue to be supported for 18 months (there's no change for these editions).

### MBR2GPT
MBR2GPT.EXE converts a disk from Master Boot Record (MBR) to GUID Partition Table (GPT) partition style without modifying or deleting data on the disk. Previously, it was necessary to image, then wipe and reload a disk to change from MBR format to GPT.
There are many benefits to converting the partition style of a disk to GPT, including the use of larger disk partitions, added data reliability, and faster boot and shutdown speeds. The GPT format also enables you to use the Unified Extensible Firmware Interface (UEFI) which replaces the Basic Input/Output System (BIOS) firmware interface. Security features of Windows 10 that require UEFI mode include: Secure Boot, Early Launch Anti-malware (ELAM) driver, Windows Trusted Boot, Measured Boot, Device Guard, Credential Guard, and BitLocker Network Unlock.

In the current version of SetupDiag there are 53 rules contained in the `rules.xml` file, which is extracted when SetupDiag is run. The `rules.xml` file are updated as new versions of SetupDiag are made available.

- WDAG is now an extension in Google Chrome and Mozilla Firefox. Many users are in a hybrid browser environment, and would like to extend WDAG’s browser isolation technology beyond Microsoft Edge. In the latest release, users can install the WDAG extension in their Chrome or Firefox browsers. This extension will redirect untrusted navigation to the WDAG Edge browser. There's also a companion app to enable this feature in the Microsoft Store. Users can quickly launch WDAG from their desktop using this app. This feature is also available in Windows 10, version 1803 or later with the latest updates.
To try this extension:
To try this extension:
1. Configure WDAG policies on your device.
2. Go to the Chrome Web Store or Firefox Add-ons and search for Application Guard. Install the extension.
3. Follow any of the other configuration steps on the extension setup page.
4. Reboot the device.
5. Navigate to an untrusted site in Chrome and Firefox.
- WDAG allows dynamic navigation: Application Guard now allows users to navigate back to their default host browser from the WDAG Microsoft Edge. Previously, users browsing in WDAG Edge would see an error page when they try to go to a trusted site within the container browser. With this new feature, users will automatically be redirected to their host default browser when they enter or click on a trusted site in WDAG Edge. This feature is also available in Windows 10, version 1803 or later with the latest updates.

- [Windows Defender Application Control (WDAC)](/windows/security/threat-protection/windows-defender-application-control/windows-defender-application-control): In Windows 10, version 1903, Windows Defender Application Control has many new features that light up key scenarios and provide feature parity with AppLocker.
- [Multiple Policies](/windows/security/threat-protection/windows-defender-application-control/deploy-multiple-windows-defender-application-control-policies): Windows Defender Application Control now supports multiple simultaneous code integrity policies for one device in order to enable the following scenarios: 1) enforce and audit side-by-side, 2) simpler targeting for policies with different scope/intent, 3) expanding a policy using a new ‘supplemental’ policy.
- [Path-Based Rules](/windows/security/threat-protection/windows-defender-application-control/create-path-based-rules): The path condition identifies an app by its location in the file system of the computer or on the network instead of a signer or hash identifier. Additionally, Windows Defender Application Control has an option that allows admins to enforce at runtime that only code from paths that aren't user-writeable is executed. When code tries to execute at runtime, the directory is scanned and files will be checked for write permissions for non-known admins. If a file is found to be user writeable, the executable is blocked from running unless it's authorized by something other than a path rule like a signer or hash rule.<br>
This functionality brings WDAC to parity with AppLocker in terms of support for file path rules. WDAC improves upon the security of policies based on file path rules with the availability of the user-writability permission checks at runtime time, which is a capability that isn't available with AppLocker.
- [Allow COM Object Registration](/windows/security/threat-protection/windows-defender-application-control/allow-com-object-registration-in-windows-defender-application-control-policy): Previously, Windows Defender Application Control enforced a built-in allowlist for COM object registration. While this mechanism works for most common application usage scenarios, customers have provided feedback that there are cases where more COM objects need to be allowed. The 1903 update to Windows 10 introduces the ability to specify allowed COM objects via their GUID in the WDAC policy.
- [Multiple Policies](/windows/security/threat-protection/windows-defender-application-control/deploy-multiple-windows-defender-application-control-policies): Windows Defender Application Control now supports multiple simultaneous code integrity policies for one device in order to enable the following scenarios:
1. Enforce and audit side-by-side.

#### System Guard
[System Guard](/windows/security/threat-protection/windows-defender-system-guard/system-guard-how-hardware-based-root-of-trust-helps-protect-windows) has added a new feature in this version of Windows called **SMM Firmware Measurement**. This feature is built on top of [System Guard Secure Launch](/windows/security/threat-protection/windows-defender-system-guard/system-guard-secure-launch-and-smm-protection) to check that the System Management Mode (SMM) firmware on the device is operating in a healthy manner - specifically, OS memory and secrets are protected from SMM. There are currently no devices out there with compatible hardware, but they'll be coming out in the next few months.
