Known issues in this update
|
Symptom |
Workaround |
|---|---|
|
After installing this 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. |
This issue is resolved in update KB5041851. |
|
After installing this update, Windows Servers might affect Remote Desktop Connectivity across an organization. This issue might occur 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 administrators can track this as a termination of the TSGateway service which becomes unresponsive with exception code 0xc0000005. |
To work around this issue, use one of the following options: 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 and set the value of RDGClientTransport to 0x00000000 (0) In Windows Registry Editor, navigate to the following registry location: HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client Find RDGClientTransport and set its value to 0 (zero). This changes the value of RDGClientTransport to 0x00000000 (0). Next step: We are working on a resolution and will provide an update in an upcoming release. |
For the current status of any past Known Issue, see the Windows Server 2012 Known Issues page.
