Windows  Automatic Update or Microsoft Update web site getting Error 403 - Access Forbidden

When using Automatic Update or the Windows/Microsoft Update web site, you might received the error "403 - Access forbidden - You do not have permission to view this directory or page using the credentials that you supplied."  We are seeing many reports of people getting this error since yesterday.

This appears to be caused by a corrupted update to a Windows Update Agent file.

The Windows update log file is in "%windir%\Windowsupdate.log".

In the log file it might say:
FATAL: Update required for C:\WINDOWS\system32\wuweb.dll: target version =
7.2.6001.788, required version = 7.4.7600.226 

What Should You Do Now

To reinstall the Windows Update Agent, download the relevant file from the appropriate links provided in the article above and save it to a drive.
