Windows – svchost.exe high memory usage – wuauserv

memorymemory leakssvchostwindows 7windows update

I'm running Windows 7, and I've been experiencing high memory usage from one of my svchost.exe processes.

svchost high memory

Services under that particular process are BITS, EAPHost, IKEEXT, LanmanServer, MMCSS, ProfSVC, RasMan, Schedule, SENS, SharedAccess, ShellHWDetection, Themes, winmgmt and wuauserv.

I've been able to narrow it down to a specific service by separating each services into its own process and identified wuauserv as the cause.

Stopping the Windows update service(wuauserv) stops the insane memory usage but that's not a solution.

Any help please?

I've have already tried re-naming the SoftwareDistribution folder and re-registering the Windows Update Agent. Nothing has worked so far.

Best Answer

In my experience, when wuauserv starts eating memory, the best thing to do is to wait until it finishes installing the updates and then reboot.

If you can't or aren't willing to reboot now, you can always reset wuauserv with the following BAT script (right click & run as administrator):

net stop wuauserv
net stop bits
rd /s /q %windir%\softwaredistribution
net start bits
net start wuauserv
wuauclt.exe /detectnow

Hope it helps.
