on a Windows XP PC.  As I wrote in Windows Update: Network policy settings prevent you from using this website …, you’d often see a Windows Update error when your Corporate IT types block access on purpose.

But wait!  I’m my Corporate IT type!  What did I do to break it for myself???

Well somewhere along the line, I configured a system group policy to block access to Windows Update, and I ended up tripping over my own trap.

The solution/work-around was to delete the
HKEY_USERS\S-1-5-18\Software\Microsoft\Windows\CurrentVersion\Policies\WindowsUpdate - "DisableWindowsUpdate" key.

Once I did that, the Windows Update site worked with no errors.

You can download a .reg file which does that, and the other two registry keys I mentioned in the earlier article, right here.
