Before this problem, Windows was behaving oddly in various ways, so I restarted the PC, which seemed to fix things. The Windows Update window still showed 5 important and 2 optional updates to be done (as it had before the restart). I ran the Microsoft

Security Essentials update through that program, not the Windows Update. After that, the 5 important updates and the other optional update had disappeared. Windows Update said it was "up to date...there are no updates available for your computer." When

I checked the update history, it only showed the MSE update as done today (and it had had no time to run the others anyway). Closing the Windows Update window and rerunning it gets the same lack of reults. They do not show up as hidden updates either.

The 5 important updates that disappeared were:

Security Update for Windows Vista (KB2393802)Security Update for Windows Vista (KB2676562)Security Update for Windows Vista (KB2799494)Update for Windows Vista (KB2679255)Windows Internet Explorer 9 for Windows Vista

The optional one was:

Windows Internet Explorer 9 for Windows Vista, a different one it said was published 5/31/2011.

I have had 1 update do a similar disappearing act previously, so today I did "copy details" for all of today's updates before updating MSE, which is how I know what disappeared.

But how do I get them back on the Windows Update window so that I can do these 6 updates? And how do I prevent this problem in future?

Thank you for any help you can give me.
