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.

Thank you so much! We were struggeling so hard because of that. It took us about 6 months and several new installed servers now. Finally fixed! 🙂
Glad I could help!
FYI: it affects also Server 2019 – I’ve covered it within this blog post – a crowded registry key seems the culprit – no idea, what populates the keys. I’ve reported it the Microsoft’s developer.

Good to know, thanks for the information!
Disabling the Touch Keyboard and Handwriting Panel Service updates the auto start registry key but will change back to Manual Trigger start within 15m and will not last a reboot (Disabled gets changed back to Manual Trigger). I also can’t manually stop the service, nor rename the TabTip.exe files.
I’m having to resort to scripting a manual deletion of the 27641370 key every hour.
Any ideas to properly disable?
Have you tried killing the process in task manager and renaming the file? Otherwise make a scheduled task that runs every hour.
Thank you so much, this really helped me out. Registry Key seems to have disappeared in the latest update though, so hopefully no one else has to suffer through this…
Nice to know, thanks !
this was an absolute god send, spent half a year tearing my hair out trying to figure out what this issue was. thank you very much.
I agree with the comments wholeheartedly. This solution is nothing short of a miracle. I suffered for almost three months trying to figure what the issue was. No one at Azure could identify the problem. I told them it’s not an Azure issue, but rather a Windows issue. Instead of connecting me with the Windows team, i never heard back from anyone. Damn Microsoft! I came close to migrating my client to AWS. Fortunately, i found this article with luck. Thank you very much AJNI.
thanks man, really appreciate it! glad this could save your infinite search!
i am curious. This appears to be a known issue for Windows 2022 & 2019. If that’s the case, why doesn’t Microsoft publish a patch? Is it because they’re afraid they’d break something else while trying to fix this problem?
Just rolled out server 2022 and had slow explorer and slow laggy menus/window dragging. This has helped. How did you find this solution?
I had to google a lot to find this issue it was a pain
Can you just uninstall Teams?
