Hi there!

Last three flights i have experienced Win Search problem - high CPU usage. When working at notebook, all seems ok (snapshot above - while working). As soon as i afk (notebook is idle), abovementioned service starts its work, notebook's fans produce a lot of noise. When i resumes work - notebook became laggish, irresponsible for 1-1.5 minutes. Also indexing algorithms work well while notebook works on battery.

 

Win search settings:

 

WinSearch_2.jpgIf Windows Search Service stopped and disabled - everything runs smoothly, no any fan noise, no any lags (nor on plug or battery)

Win Search disabled.

 

Best regards.

Joshua

Have you tried letting it to its thing for few hours and see if it finally finishes and the CPU usage goes down?
