Svchost.exe plug and play using CPU cycles only when Steam is active

[Elitehunter34]

I'm not sure if it's always been like this, but I find it strange how svchost.exe plug and play is using CPU cycles only when Steam is active. Offline mode doesn't seem to make a difference. I don't have any controllers plugged in at the moment, but I do use an Xbox 360 controller sometimes. Restarting my computer also didn't seem to make a difference. I don't remember this happening before. To be fair, it's only using 1-2% of my CPU, but I don't see why it's even active in the first place.

big picture mode works for me to, thanks alot! I will also send it to my open ticket.

This problem also happened on Castle Crashers.

Just posting this here to add another possible solution for people with issues.

Today I noticed that Steam.exe on my computer was occupying one whole CPU core as well constantly. Switching to Big Picture mode and back did not fix it for me, neither did enabling Push-To-Talk as someone had suggested. Process Explorer showed that the main thread of Steam.exe was hogging all the CPU for whatever reason.

What worked for me was switching the Library view from the Full Details view to one of the other views (list, icons) and back. Steam.exe is happily using ~0% afterwards when idle, which is how it should be.

Maybe just re-install steam, back your games up first though! Sorry I can't be more help!

This solution didn't work for me (changing to big picture and back). Plus, its not an automated solution; even, if it did work. I was able to safely do this by making a powershell script suspending two specific process threads under two different processes (steam and steamwebhelper)... in a specific order. My script runs on Windows startup (shortly after Steam launches).

There are 2 process threads that keep blindly banging away at the CPU (albeit, only consuming less than 1.5% of my fast 4.4Ghz multicore CPU) when Steam is idle. This activity appears to be "by design". Anyway, now, Steam consistently uses 0% CPU (when I'm not using the Steam app). Steam will still process updates on startup. The suspended threads will go active only when they're actually needed.

Since Its pretty clear to me that Steam developers intended for Steam to work this way; I will NOT be posting the actual code to do this. I would rather stay in good standing with Steam and Steam community. :) ...just know, there's a programmatic automated solution for this.
