Repair Windows Updates After Removing Fake Anti-Virus in XP

After removing a fake Anti-virus the XP PC would not do any Window’s Updates. Found this on the web:

Open C:\Windows

Show hidden files and folders

Open C:\Windows\inf

Right click au and select install (extension hidden by default, should be only file named au)

After install complete may ask for restart, if not restart anyway

Hide hidden files and folders

Windows updates should now work


MS now makes a great Fixit Utility that should fix all Windows Updates issues

    I am having this problem now and when I try to fix it with your advice, I am having yet another problem. When clicking install under au, I get this message:

    “The file ‘wuapi.dll’ on Windows Professional Service pack 3 is needed. Type the path where it is located and click ok”

    Any suggestions on how to fix this?

  • Hello Brandon,

    I found this on MS site. Try it and see what happens. If it does not help let me know. Thanks, Steve


  • Hello Steve,

    I didn’t find any contact info so I’m writing here. My name is Michael and I run http://deletemalware.blogspot.com. I write about malware, mainly rogue antivirus products, Trojans and adware. I would be really happy if could a link to my blog to your websites. I updated my block at least a couple of times a week, sometimes daily. I thought that maybe some of your visitors may find my blog useful. Thank you in advance. P.S. feel free to contact me if you have any questions.

    Best regards,
