Having odd issues with the task bar/random task bar freezing on Windows Server 2022 RDS? Or explorer.exe using around 10% of the CPU for every user that is logged in? This might save your day. This issue occurs if you have MS Teams installed on the RDS.

First of all, export the registry path HKLM\SYSTEM\Software\Microsoft\TIP\TestResults\27641370 and look at the file size. If it is around 40MB in size, then you have the same issue.

To resolve the issue, delete the key and disable the TabletInputService service (Touch Keyboard and Handwriting Panel Service). Afterwards, take ownership of C:\Program Files (x86)\Common Files\Microsoft Shared\ink\TabTip32.exe and C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe and rename both executables into TabTip32.exe.orig/TabTip.exe.orig.

After that, reboot your server.

$cert = Get-ChildItem -Path Cert:\LocalMachine\My\ | where { $_.Thumbprint -eq “thumbprint” }
