Тормоза в сервере терминалов 2022 и реестр

Server 2022 and Teams Bloats HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\TIP\TestResults\

Hi, has anyone else deployed MS Teams on Server 2022 and noticed bloating of the registry key:
We need to clear this daily to prevent slow downs. 


I have a 2022 RDS Server and was beating my head with issue for about 3 months now! The issues were random lag and slowness and more so when switching between apps. Tried so many troubleshooting it was crazy. It wasn’t until I stumbled across this post that after implementing the changes, users have now reported no issues with lag or slowness (implemented 6 days ago and no issues since)!

What lead me to this was finding out explorer.exe was randomly sitting at 12%-20% CPU for some users. If I restart explorer.exe for that user, it would fix temporarily but then another user would have the same issue. CPU would also spike overall to 70%-99%.

My changes:

  1. The HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\TIP\TestResults reg key when I exported it was 42MB in size! That shows how massive it was. I deleted all subkeys under that
  2. Disabled the TabletInputService service (Touch Keyboard and Handwriting Panel Service)
  3. Took ownership of C:\Program Files (x86)\Common Files\Microsoft Shared\ink\TabTip32.exe and renamed it (to prevent it from starting up and adding to TestResults key)
  4. Took ownership of C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe and renamed it (to prevent it from starting up and adding to TestResults key)
  5. Rebooted server

After the changes, Explorer.exe no longer has high CPU usage. CPU overall is good, and users are happy and not reporting any lag or slowness. Such a random and odd issue. Glad I’ve found this and thank you everyone for sharing.

Here is what I’ve been running when I hit this issue now:

taskkill /f /IM tabtip.exe
taskkill /f /IM tabtip32.exe

takeown /F «C:\Program Files\Common Files\microsoft shared\ink\tabtip.exe»
cacls «C:\Program Files\Common Files\microsoft shared\ink\tabtip.exe» /T /E /P Administrators:F
cacls «C:\Program Files\Common Files\microsoft shared\ink\tabtip.exe» /T /E /P SYSTEM:F
ren «C:\Program Files\Common Files\microsoft shared\ink\tabtip.exe» tabtip.exe.old

takeown /F «C:\Program Files (x86)\Common Files\microsoft shared\Ink\tabtip32.exe»
cacls «C:\Program Files (x86)\Common Files\microsoft shared\Ink\tabtip32.exe» /T /E /P Administrators:F
cacls «C:\Program Files (x86)\Common Files\microsoft shared\Ink\tabtip32.exe» /T /E /P SYSTEM:F
ren «C:\Program Files (x86)\Common Files\microsoft shared\Ink\tabtip32.exe» tabtip32.exe.old

Reg Delete HKEY_LOCAL_MACHINE\SYSTEM\Software\Microsoft\TIP\TestResults\ /f
