wuauserv causing svchost memory usage to explode
To be honest, I started out investigating the wrong thing. This all started because I would have errors in Chrome. The Aww, Snap or It's Dead Jim errors, etc. Or Chrome would just crash and I would relaunch and restore. I did normal Chrome things like check the shockwave and flash files, disable extensions, and finally created a new user profile. But I still got application exception errors after that.
Then I saw it.
I had Task Manager open and saw one of the svchost instances jump from a normal 22,988 K to 995,688 K!!! And then saw it go higher! And at the bottom of task manager, my Physical Memory was at 86% instead of it's normal 30-40%.
So first I looked at which services were associated with that svchost process. The services were: BITS, Browser, IKEEXT, iphlpsvc, LanmanServer, ProfSvc, Schedule, SENS, ShellHWDetection, Themes, Winmmt, & wuauserv.
Of those, the only one I knew exactly what it was associated with was wuauserv. So I stopped that service. As *SOON* as I stopped it, the memory for svchost dropped back down to normal.
So I left wuaserv stopped and set startup to Manual.
About 15 or 20 minutes later, something started it back up and memory exploded to the same levels again. So I stopped it and again, memory usage dropped back down. This time I set wuauserv startup to Disabled.
So, I guess what I am looking for is suggestions on what to troubleshoot or clear or cleanup so that I can start wuauserv without the excessive memory usage causing exception errors and causing Chrome to crash.
