WindowsUpdate_80004002 Error in Windows Vista Ultimate - It has been running flawlessly for years until now.
I have tried the following:
Re-register the required dll's (from another thread)
Fixit
.Net Framework Cleanup tool
along with several other recommended fixes with no luck.
When I try Windows Update I get: Error Found Code 80004002 Windows encountered an unknown error. Most recent check for updates: Updates were installed: Never
Before trying some of the fixes as stated in the Microsoft forums I was getting the same update over and over and it would successfully install over and over. I would tell you what it is but I can't even see any updates that were installed on my comp when you go through Windows Update Installed Updates. All of my update problems started January 16 11:46pm and it's only getting worse.
Alex Microsoft Trebek, I'll take "What is Unknown Code 80004002?" for the win.
