I had the same problem. The reinstallation seems too much work for me.
The following helped me:
- PowerShell: dism.exe /online /disable-feature /feature-name=SearchEngine-Client-Package, (reboot necessary).
- via Services.msc I stopped "Windows Search" and then quickly deleted the files under C:\ProgramData\Microsoft\Search.
- PowerShell: dism.exe /online /enable-feature /featurename=SearchEngine-Client-Pack, (no reboot required).
The index is as fast as it was before...
Good luck.
I did everything as described but unfortunately this didn't work for me. Curious to hear what others have to say.
Oh and if you want us to copy-paste commands into PowerShell/Terminal, please at least make sure those commands are correct. Yours include typos.
The correct commands are:
dism /online /disable-feature /featurename:SearchEngine-Client-Package
dism /online /enable-feature /featurename:SearchEngine-Client-Package
