After installing the July 2024 Windows security update, released July 9, 2024 (KB5040431), you might see a BitLocker recovery screen upon booting your device. This screen does not commonly appear after a Windows update. You are more likely to face this issue if you have the Device Encryption option enabled in Settings under Privacy & Security -> Device encryption. Resulting from this issue, you might be prompted to enter the recovery key from your Microsoft account to unlock your drive.
Resolution: This issue was resolved by Windows updates released August 13, 2024 (KB5041592), and later. We recommend you install the latest update for your device as it contains important improvements and issue resolutions, including this one.
If you install an update released August 13, 2024 (KB5041592) or later, you do not need to use a workaround for this issue. If you are using an update released before August 13, 2024, and have this issue, your device should proceed to start up normally from the BitLocker recovery screen once the recovery key has been entered. You can retrieve the recovery key by logging into the BitLocker recovery screen portal with your Microsoft account.

Updates to Edge browser version 123.0.2420.65, released on March 28, 2024, and later, might incorrectly install a new package (MSIX) called ‘Microsoft chat provider for Copilot in Windows’ on Windows devices. Resulting from this, the Microsoft Copilot app might appear in the Installed apps in Settings menu.
It is important to note that the Microsoft chat provider for Copilot in Windows does not execute any code or process, and does not acquire, analyze, or transmit device or environment data in any capacity.
This package was intended to prepare some Windows devices for future Windows Copilot enablement and was not intended for all devices. Although the component installed as part of this issue can cause the Microsoft Copilot app to be shown as part of the Installed apps, this component does not fully install or enable Microsoft Copilot.
Note: Edge browser version 124.0.2478.51, released on April 18, 2024, contains a change by which the chat provider for Copilot in Windows will not continue to be installed on every device.
Resolution: This issue is now resolved with Edge browser updates released on April 26, 2024, and June 13, 2024. Edge version 124.0.2478.67 was released on April 26 and removed the package ‘Microsoft chat provider for Copilot in Windows’ from all servers affected by this issue. Edge version 126.0.2592.56 was released on June 13, 2024, and removed the same package from all Windows client versions affected by this issue. The ‘Microsoft Copilot’ entry will not show in the Installed apps list in the Settings menu once the Edge browser is updated.
Affected platforms:

Devices attempting to install the January 2024 Windows Recovery Environment update (KB5034440) might display an error related to the size of the Recovery Environment's partition. The Windows Recovery Environment (WinRE) is used to repair or recover from issues affecting Windows.
Resulting from this error, the following message might be displayed.
- "0x80070643 - ERROR_INSTALL_FAILURE"
Important: If your Windows device does not have a recovery environment configured, you do not need this update (KB5034440). In this case, the error can be ignored.
To determine whether your device has a recovery environment configured, inspect the WinRE status by following these steps:
- Open a Command Prompt window (cmd) as admin.
- To check the WinRE status, run reagentc /info. If the WinRE is configured, a "Windows RE status" field will appear in the output, with value "Enabled". If WinRE is not configured, this field will have the value "Disabled".
Resolution: Automatic resolution of this issue won't be available in a future Windows update. Manual steps are necessary to complete the installation of this update on devices which are experiencing this error.
The WinRE partition requires 250 megabytes of free space. Devices which do not have sufficient free space will need to increase the size of the partition via manual action. For guidance on making this change, review the following resources:
- A code script can be used to extend the partition size. A sample script has been provided in the documentation for adding an update package to WinRE. See Extend the Windows RE Partition.
- Guidance to manually change the WinRE partition size can additionally be found in KB5028997: Instructions to manually resize your partition to install the WinRE update.
Completion of these manual steps will allow the installation of this update to succeed.

The correct default currency might not display or be used in Windows devices which have locale set to Croatia. This can affect applications which retrieve the device's currency for purchases or other transactions.
Earlier this year, Croatia joined the Eurozone, changing its currency from the Kuna to Euro. Windows Locale data for Croatia will be updated for this change in the short term.
Workaround: Changing the currency in Windows can help. This can be accomplished via the Windows Control Panel.
- Open the "Windows Region" settings. This can be done in one of the following ways:
- Open "Control Panel" from the start menu and select "Change date, time, or number formats" under "Clock and Region"
- On your keyboard, press and hold the Windows key, then press the letter R. This will open the "Run" window. Type INTL.CPL into the Open field,
- In the Region settings, choose one of the 2 locales for Croatia:
- Croatian (Bosnia & Herzegovina)
- Croatian (Croatia)
- In this same window, click the "Additional settings" button. Once there, click the "Currency" tab.
- Change the currency symbol from "KN" to Euro, "€"
Additional information can be seen here: Currency formatting - Globalization | Microsoft Learn.
Manually changing currency might also be an option in some applications. Although this won't change the device’s default currency, this could allow usage of the application with the desired currency preference. Some applications might not allow this manual change. Please view the settings and documentation for your applications.

Intel and Microsoft have found incompatibility issues with certain versions of drivers for Intel Smart Sound Technology (Intel SST) on Intel 11th Gen Core processors and Windows 11. Windows 11 devices with the affected Intel SST driver might receive an error with a blue screen. The affected driver is named Intel® Smart Sound Technology (Intel® SST) Audio Controller under System Devices in Device Manager and is found with the file name 'IntcAudioBus.sys'. If this file is version 10.29.0.5152 or 10.30.0.5152, this issue can occur.
Only devices with both an Intel 11th Gen Core processors and an Intel SST driver version of 10.29.0.5152 or 10.30.0.5152 are affected by this issue.
To safeguard your upgrade experience, we have applied a compatibility hold on Windows 10 devices which have Intel SST driver versions 10.29.0.5152 or 10.30.0.5152. This will prevent those devices from being offered any version of Windows 11. If your organization is using Update Compliance, the safeguard IDs are:
- Windows 11, version 21H2: 36899911
- Windows 11, version 22H2: 41291788
- Windows 11, version 23H2: 49561482
Resolution: Devices which are encountering this issue will need to install newer versions of the Intel® SST Audio Controller drivers prior to updating to Windows 11. The issue is resolved by updating the Intel® Smart Sound Technology drivers to version 10.30.00.5714 and later, or 10.29.00.5714 and later. Please note that later versions of this driver might refer to only the last part of the version number. For the purpose of addressing this issue, 10.30.x versions are not newer than 10.29.x versions.
For most users, updated drivers can be installed via Windows update by checking for Windows updates on your device. This is the preferred method of installing these and other drivers. If your device still encounters this safeguard hold 48 hours after updating your drivers, it's possible drivers for this Audio Controller haven't been developed for your specific device hardware configuration. In this case, you will need to contact your device manufacturer (OEM) for more information on the necessary drivers. Microsoft works to make the latest compatible drivers available under Windows Update whenever developers have released them.
IT admins in organizations where devices are managed can refer to the following resources to deploy drivers using one of these tools:
- Windows Update for Business customers: Deploy drivers and firmware updates - Windows Update for Business deployment service
- Intune: Learn about Windows Driver updates policy for Windows 10 Windows 11 devices in Intune
- Autopatch: Manage driver and firmware updates - Windows Deployment
Once you have updated to a compatible version of the Intel® Smart Sound Technology drivers, you should be able to upgrade to Windows 11. Please note, if there are no other safeguards that affect your device, it can take up to 48 hours before the upgrade to Windows 11 is offered. We recommend that you do not attempt to manually upgrade using the 'Update now' button or the Media Creation Tool until you have performed the necessary driver updates.
Affected platforms:
- Client: Windows 11, version 23H2, Windows 11, version 22H2; Windows 11, version 21H2
