They get crashes in the RDS infrastructures, black screen, hanging login, sporadic hang, and even more issues due to the patch.

A German Tech blog Born IT has claimed to fix it using KIR or Known Issues Rollback process This unofficial fix may be helpful for the users encountering problems in the RDS infrastructure because the KIR will bring the Security update back to a suitable state. Cumulative Update KB5015808 comprised a long list of bug fixes but the release badly affected RDS users with several errors. The patch addressed Serchindexer.exe, Wi-Fi hotspot, Encrypted File System (EFS), 0xc00000dd BitLocker virtual machine-based (VM) system files, and more.
RDP Errors after KB5015808 in Windows 10
Here is How to Fix RDP Errors after KB5015808 in Windows 10 –
Way-1: Through Known Issue Rollback or KIR
KIR aka Known Issue Rollback is the process that can instantly bring an impacted device back to productive use if a problem occurs because of an update. This process fixes errors through restore of a device to the previous state removing the specific problem. The most important thing about this method you don’t need to uninstall a Windows update when getting an error. Known Issue Rollback disables the problematic fix and again enables the previous code, instead of uninstalling the whole update.
According to Microsoft, they have opened different support requests (cases) related to this problem. The August 2022 security patch didn’t fix the error described above, but the company contacted them. One of those people provided a link to run Known Issue Rollback so follow the steps –
- Click on the link – KB5015808 220809_20051 Known Issue Rollback.msi to download the KIR MSI file for Windows 10 1607 and Windows Server 2016.
- Once downloaded, double-click and run the file.
- On the Known Issue Rollback Policy Definitions Setup window, click on Next.
- Select Yes from User account control prompt.
- Click on Finish.
- If you want to enable or disable this KIR from Group Policy Editor manually then go to – Computer Configuration > Administrative Templates (KB5015808 220809_20051 Known Issue Rollback).
- Double click on the folder – Windows 10, version 1607 and Windows Server 2016.
- Right click on “KB5015808 220809_20051 Known Issue Rollback” and select Edit.
- If you want to disable this rollback, click on ‘Disabled’.
- Select Apply and OK.
Way-2: Using Registry Editor
One easy solution to the errors that occur because of RDP problems goes through the uninstallation of the patch but being an administrator this is not a good idea from the perspective of security. Apart from this, the company didn’t push any update to address the RDS issues in the subsequent months. Most of all, Microsoft still says in the release note of KB5015808 that there are no known issues. Fortunately, you can try registry editor to solve the problem –
- Press Window and R.
- Type Regedit to open Registry Editor.
- Click on OK.
- Select Yes on the UAC prompt.
- Navigate to the following key –
- From the right pane, right-click and select New > DWORD (32-bit) Value.
- Name the DWORD value 254221451.
- Double click on “254221451” and change the Value data from 0 to 1.
- Press – Enter.
- Restart your computer to fix the RDP errors.
This registry modification would disable the fix out with KB5015808 and the August patch that triggered these problems.
