Windows update not working after SP3
So, a while back, more specifically when Microsoft pushed XP Service Pack 3 onto Windows Update we started experiencing some problems. After SP 3 had been sucessfully installed, all attempts to update via Windows Update failed. A couple of friends that works in other organizations reported the same problems.
After some extensive research I found out that Microsoft had upgraded Windows Update in SP 3, which to me seemed like a plausible source of the problem.
I checked my version only to find that I ran the old one; something wasn’t right. So, after deep diving into my %systemroot%\system32\ folder I spotted the dll file for the new version, wups2.dll. Since it had not been loaded properly I decided to engage in some trial and failure.
Suspecting that the installation of Windows Update 2 had failed at some point I took a shot in the dark and tried to register the dll so Windows would reckognize it. And voila, it worked!
I am aware that there are fixes available from Microsoft for this issue, but if you’d like to save yourself some time try this little hack (it requires administrative rights on the machine you’re fixing):
Hit start, run and type cmd to bring up a command line prompt.
First you’ll have to stop the Windows Update service. Type “net stop wuauserv” and press enter.
Second, and this is the magic, register wusp2.dll. Type “regsvr32 %systemroot%\system32\wups2.dll” and press enter.
If all goes well you’ll now be able to restart Windows Update with “net start wuauserv”.
Hooray!
