Windows Update high CPU usage fix

I have recently experienced a problem with Windows Update (wuauserv) peaking out the CPU - it hit 50% and that almost freezes the PC. The process that shows using the CPU is (svchost)

Process Listing

After searching the internet I have found one script that seemed to work well. Please follow these simple steps outlined below:








1) Copy code listed below and save as windowsupdate.bat on your desktop


2) Run it just by double-clicking the file


net stop wuauserv
net stop bits
net stop cryptsvc

deltree /Y %systemroot%\SoftwareDistribution_Old
ren %systemroot%\SoftwareDistribution SoftwareDistribution_Old

regedit /s "WSUSReset.reg"

REGSVR32 /s WUAUENG.DLL
REGSVR32 /s WUAUENG1.DLL
REGSVR32 /s ATL.DLL
REGSVR32 /s WUCLTUI.DLL
REGSVR32 /s WUPS.DLL
REGSVR32 /s WUPS2.DLL
REGSVR32 /s WUWEB.DLL

net start wuauserv
net start bits
net start cryptsvc

wuauclt.exe /resetauthorization /detectnow
