Biggest pain in the @$$ issue I have seen so far on Windows XP. You remove tons of viruses, get everything working, and then all the sudden Windows Update doesn’t work anymore, gives a dumb error. [Error number: 0x8024D007]
The first issue is that windows wont update. The second is that you start getting locked out of all kinds of things due to system administrative policy issues.
So I decide to download Microsoft’s Fix it tool for Windows Update Issues to have it fix it for me. NO SUPRISE
