cannot close, minimize or move windows in Vista Ultimate 32 bit OS

I too am experiening this problem. It looks like a new issue that
Microsoft has not addressed yet. Have you ever heard of a repair to
the OS? You go through the process of reinstalling, but you get to a
point where the disk searches for previous versions of Microsoft
installations and it should detect your Vista OS. It then gives you
the option to repair.

You do not have to reinstall everything. It repairs the baseline OS
system files, but keeps all of your documents and applications in
tact. You may have to reinstall Microsoft updates, but it beats hving
to backup, reinstall and restore everything.

I am an IT consultant and this has saved my butt, a few hundred
times. I plan to do this tonight. I will try to update.

I had the same problem.
go to C:\Windows\System32\en-US and search for user32.dll.mui
The file may have other similiar files such as user32.dll.mui.bak that you can use to replace it. I had to use the user32.dll.mui file from another computer running Vista.
If it won't let you rename or copy the file, you will have to take ownership first. This site shows how to do that. mydigitallife.info/2007/05/25/how-to-take-ownership-and-grant-permissions-in-windows-vista/
