svchost.exe high memory usage – wuauserv

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.
