if uts only been a few days, it could be initial scans and updates for defender.With the latest version of W10 my SP3 is running a lot hotter and the fan is blasting pretty much full speed even when just browsing. Under 8.1 it almost never ran at all.
Anyone else? The thing that seems to be running a lot and using up CPU is Windows Defender but I'n not running any virus scans at all. Why would Defender be running so hard?
P.S., Just noticed that Defender is in fact running a virus scan. Weird. I didn't tell it to do that and none were scheduled.
I actually find running avg to be easier on the system than running stoc defender
