When I first heard about a friend having this problem I didn’t think much about it. Then I started having problems as well.
Windows Search Index / SearchIndexer.exe is a Windows service that indexes files allowing for a faster search. Some argue that it slows down your computer because it requires additional space and resources, and some benchmarks have shown that it might be so on low end computers.
There seems to be a few problems with the indexer, and I’ve noticed two problems.
1. Search on Windows 8 / Windows 8.1 suddenly stops working. On Windows 8.1 it works in the Apps mode, but I want to search files
Open Task Manager ( Ctrl + Alt + Delete => select Task manager or right click on toolbar and select Task Manager)
Select Microsoft Windows Search Index and right click, End task
2. Windows Search Index / SearchIndexer.exe stops working
Delete following folders (Folders might be hidden, select View in Explorer and select show hidden):
If you have a different fix, let me know I’ve installed all updates and fixes, and I’m running the Windows 8.1 Preview – but had the same problem on the Windows 8 (but not so frequent)
