Hello, i disabled indexation but when computer's on screensaver, i hear the fan firing up and when unlocking session, i see temperatures are up to 70C° and quickly drop down to 55C°. What's causing this?

Hi,
Well it will at least confirm you have the updates that have been curing high cpu usage installed
Then we can go from there after you try and see if you're missing any other important windows updates.

I indeed had WU update issue. But not anymore, still CPU is used while idling on lockscreen.
