After installing the July 9, 2024, Windows security update, you might see a BitLocker recovery screen upon starting up 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. Because of this issue, you might be prompted to enter the recovery key from your Microsoft account to unlock your drive. |
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 signing into the BitLocker recovery screen portal with your Microsoft account. Detailed steps for finding the recovery key are listed in Finding your BitLocker recovery key in Windows. We are investigating the issue and will provide an update when more information is available. |

Windows Servers might affect Remote Desktop Connectivity across an organization if legacy protocol (Remote Procedure Call over HTTP) is used in Remote Desktop Gateway. Resulting from this, remote desktop connections might be interrupted. This issue might occur intermittently, such as repeating every 30 minutes. At this interval, logon sessions are lost and users will need to reconnect to the server. IT admins can track this as a termination of the TSGateway service which becomes unresponsive with exception code 0xc0000005. |
Option 1: Disallow connections over pipe, and port \pipe\RpcProxy\3388 through the RD Gateway. This process will require the use of connection applications, such as firewall software. Consult the documentation for your connection and firewall software for guidance on disallowing and porting connections. Option 2: Edit the registry of client devices, by removing a key related to RDGClientTransport Important: This article contains information about how to modify the registry. Make sure that you back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, see How to back up and restore the registry in Windows . Open the Windows Registry Editor and navigate to the following registry location: Find the registry key titled ‘DWORD’ and set the ‘Value Data’ field to ‘0x0’. Next steps: We are working on a resolution and will provide an update in an upcoming release. |
