I am using Windows Vista Business. I installed the Microsoft "critical updates" via the Windows Update tool on September 14, 2010. After rebooting, the theme seems to have changed to the "Windows Classic" style, and all of the options I've looked at in Personalization and and Themes don't allow me to change it back. I've been using the Windows Vista "look" for more than 2 years, along with the Aero transparent window features, and now they're gone! The "Themes" menu doesn't even list any other themes besides Windows Classic.

I know about System Restore, and will probably try that if my back really gets up against the wall, but before I get to that point does anyone know of something I might try to get my regular Vista UI back that doesn't involve reversing the windows updates, reintalling windows, or buying Windows 7?

The updates I installed, specifically, are:

* Security Update for Windows Vista (KB981322)
* Security Update for Windows Vista (KB2347290)
* Security Update for Windows Vista (KB975558)
* Security Update for the 2007 Microsoft Office System (KB2288621)
* Definition Update for Windows Defender (Definition 1.89.1620.0)
* Windows Malicious Software Removal Tool - September 2010 (KB890830)
* Update for Windows Mail Junk E-mail Filter [September 2010] (KB905866)
* Update for the 2007 Microsoft Office System (KB2284654)
* Update for Windows Vista (KB2141007)

Thanks!

**More Info Added:**

I've discovered that when I go to "Performance Options", and view the "Visual Effects" tab, and select the "Custom" radio, I am unable to check either the "Enable Desktop Composition" and "Use Visual Styles on Windows and Buttons" checkboxes. When I check them and then click "OK", then reopen "Performance Options", they are unchecked again.
