Howdy,

 

Like the title says...on my Dell XPS 13, 25% of the processing power is often being taken up by svchost.exe (with increasing frequency and duration), and it's burning my lap. If I look at the services using (being used by?) the process in task manager, it's a short list:

 

Appinfo

AeLookupSvc

Browser

LanmanServer

wuauser

Winmgmt

 

I also see MMCSS and ProfSvc, but I'm pretty sure those aren't always running when this is happening.

 

Is this normal behavior? Antivirus and antimalware find nothing. Is there a way to see specifically which service is doing this?

 

Thanks!

I took a guess and killed the Windows Update service. It was a good guess. Now, why is Windows Update running out of control?

 

Found a relevant thread on StackExchange, which lists several updates that might fix the problem:

So for anyone with the same problem, there's your answer. As long as you're okay installing the poorly documented "convenience rollups" that Microsoft started putting out in June, you probably don't have this issue.
