As I knew that the Cortana process always respawns, I killed the Cortana task from Task-Manager. Surprisingly it didn't restart by itself.
Now I have the following problems
- My start menu takes ~1.5 Seconds to show up every time!
- I could type stuff in the start menu and it would start searching. Doesn't work anymore.
- The Cortana and Search-Settings are gone from the control panel! I can search for it with the search bar and it will show me "Cortana & Sucheinstellungen" as a result, but clicking on the result won't take me to the Cortana settings.
How do I solve (at least) the first two problems?
How do I start the Cortana process again?
(A restart doesn't fix this!)
I found SearchUI.exe in
C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy and executed it, but that didn't work.
Edit 2: It turned out that I had a trojan. Windows Defender removed it for me and after a restart Cortana is back again.
