Make sure your firewall is not blocking the Update site and check any pop up
stopper programs. Now check in IE tools\manage add-ons (Win XP SP2 only)
making sure that WuWebControlClass is enabled. You may also wish to check
c:\windows\Downloaded Program Files to see if anything is corrupted there.
If the above appears to be in order, try re-registering these files, by
clicking Start, Run and typing:-
REGSVR32 C:\WINDOWS\system32\wuapi.dll
REGSVR32 C:\WINDOWS\system32\wuaueng.dll
REGSVR32 C:\WINDOWS\system32\atl.dll
REGSVR32 C:\WINDOWS\system32\wucltui.dll
REGSVR32 C:\WINDOWS\system32\wups.dll
You should receive a successful message after each one.
If you need to remove the Windows Update ActiveX controls and re-install
