Did you do the trusted sites thing?
Open Internet Explorer > Tools >Internet Options > Security > Click 'trusted
sites' icon >Click Sites > uncheck 'require server verification'
Then add following sites :
http://*.windowsupdate.microsoft.com
http://*.windowsupdate.com.
If that doesn't work the likely cause of those error codes is missing or corrupted files:
WINHTTP.DLL, WUAUCLT1.DLL, WUAUENG1.DLL, WUAUSERV.DLL, CDM.DLL, WUAPI.DLL,WUPS.DLL,WUCLTUI.DLL, & IUENGINE.DLL
(all in the \windwos\system32 directory)
Try uninsatlling and reinstalling Live Toolbar if you have it installed.
Also has this computer recently had a virus?? If the files in the system32 directory are owned by admin rather than by system this will stop the automatic updates. SEt the the file ownership back to system
If still not working open a command prompt as an administrator, and type the following commands. Press entter after each command:
regsvr32 wuapi.dll
regsvr32 wuaueng.dll
regsvr32 wuaueng1.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
regsvr32 wups2.dll
regsvr32 wuweb.dll
^ You may get some errors on the above.
Finally: If all eslse fails you can always runa system file check (SFC) as admin run:
sfc/scannow
However you may need to reinstall some drivers (sounds/graphics etc., after running this)
that's all from me
