[Error number: 0x8024800C] running Windows update

Trent Here,

I recently ran into a problem on some machines that were failing to run windows update. The web service would fail with the following [Error number: 0x8024800C]

 I found several posts related to connection errors between a proxy server and firewall settings however none of these applied to my scenario. Looking at the windowsupdate.log file didn't help much either:

I was able to find the following: http://technet.microsoft.com/en-us/library/cc720442(WS.10).aspx on the Windows Update Agent Result codes

Data Store
0x8024800C WU_E_DS_LOCKTIMEOUTEXPIRED The data store section could not be locked within the allotted time.

So the "Data Store" is actually C:\Windows\SoftwareDistribution\DataStore. Interesting.  http://support.microsoft.com/kb/971058.

The article was not identicle to what I was seeing but gave me some good ideas


From a command line - net stop "Automatic Updates" 

del C:\Windows\SoftwareDistribution\

net start "Automatic Updates" 

After that I simply ran windowsupate again and it worked perfectly.

    In Windows 7, change "Automatic Updates" to "Windows Updates". I made that minor modification and your tip worked perfectly. Thank you!

    Thanks!  Fix worked great on my Win 7×64 laptop.  Should note that it can take extra long to run the updates right after the fix, but that is small price to pay to get things working again.
