Dear Glentech,
The KB5065426 update, released as part of the September 2025 Patch Tuesday rollout, has been associated with several issues on Windows 11 24H2 systems, including:
Crashes in legacy applications like Remote Desktop
Inconsistent update reporting in wusa.exe, especially on ARM-based devices
SMB and network credential disruptions
Here areRecommended Steps
1. Verify Update Installation via DISM Sometimes wusa.exe may not reflect updates installed via cumulative packages. Try checking with DISM:
cmd
dism /online /get-packages | findstr KB5065426
If listed, you can attempt removal using:
cmd
dism /online /remove-package /PackageName:<exact package name>
2. Use System Restore (if available) If the issue began immediately after the update, consider restoring to a previous system state:
Go to Settings > System > Recovery > Open System Restore
Select a restore point prior to the KB5065426 installation
3. Check for App Compatibility Updates Microsoft may release compatibility fixes for ARM-based systems. Visit the Windows Release Health Dashboard to monitor updates related to Remote Desktop and KB5065426.
4. Temporary Workaround If mstsc.exe continues to crash, consider using Remote Desktop Web Access or Remote Desktop from another device until a patch is released.
