I do hope this is the right forum to ask this question. I built my PC back in February. It runs Win7 Professional and I have messed around with all of the default services to try and optimize performance here or there.
However, I discovered a very strange issue when my PC disconnects from my network. I am connected through Ethernet to my AT&T modem. Occasionally, the modem decides to restart itself, temporary kicking me off of the network. Upon doing so, my computer will freeze to a near halt, where the mouse cursor will freeze and be extremely laggy. I've tracked it down to a single process, svchost.exe. Even when my computer is reconnected to the network, this svchost.exe will continue eating up more and more memory as well as my CPU. After awhile (10+ minutes), it will eventually start dropping again and my computer will not hit the speed it should be at unless I do a reboot.
This svchost.exe pertains to these services:
EDIT: WinHttpAutoProxySvc seems to have removed itself after I posted this...?
I am not sure if one of these are the actual cause of all of this. I can completely replicate my issue by just unplugging my Ethernet cable. Is there a way for me to find out through Process Explorer?
Another note, I can actually kill this svchost.exe and my PC runs better than ever. The process does not get restarted by my usual applications (Chrome, Dolphin emulator + netplay, etc.). This means I must kill it upon startup though.
I should also add, the WinHttpAutoProxySvc seems to have been added by something else I believe since the path is entirely in lowercase while the others seem to popular capitalization for the folders. I am probably wrong but I am pointing this out regardless.
This is also a legit svchost.exe as far as I am aware. It starts up in the right place and is never detected by any scanners I have used in the past (MBAM, Avira).
