AU Check : Windows Update and Automatic Update Fix/Reset Utility

Have trouble installing updates from Windows Update? Check out the Automatic Update and Windows Update Reset Tool (AU Check) written by Eddie Bowers of Microsoft, which resolves most of the Windows Update and Automatic Update issues by resetting the Windows Update configuration.

This tool automates the most common fixes to issues with the AU Client (Windows Update agent) and the Windows Update site. The script does the following:

• On Vista and 2008 it downloads and runs the Latest checksur
• Re-registers all WU related DLLs
• Renames the softwaredistribution\download folder
• Checks the Service Object Security for WUAUSERV and BITS
• Logs then Clears BITs Queue and BITS state files
• Restarts AU and BITS services
• It incorporates some registry checks (FilesNotToBackup) entries that can prevent BITS from starting.
• Creates an updates.htm in the C:\AULOGS directory with links to all the prerequisites for the update process.
• Creates several troubleshooting logs in C:\AULOGS in case the tool fails to fix the problem.
• Tests PROXYCFG and writes a log indicating if the WinHTTP call succeeded (c:\aulogs)
• Dumps output to detect MSXML registration problem (c:\aulogs)
• Tests WGA using the mgadial tool and writes the output to a file in c:\aulogs.

This supports Windows 2000, 2003, XP, Vista and 2008 x86 or x64.

My friend and fellow MVP Bill Castner provides more information about this tool, and also lists out the manual troubleshooting steps to fix WU/AU problems.
