How to Turn On Aero Glass after Windows Vista Disables It
From time to time, Vista concludes that it just can’t handle Aero Glass anymore. Sometimes Vista decides there's just not enough memory to handle it, or a program you run doesn't agree with Aero Glass. Whatever the reason, you need to know how to turn on Aero Glass after Windows Vista disables it.
You know you have a problem if you receive a Windows message to the effect that some visual elements have been turned off. But even without the message, you might notice that the glass effect has simply gone away. Typically, Vista will just drop Glass when it encounters an error, but occasionally it’ll drop way back to the Vista Standard shell.
If Vista drops Aero Glass, you first need to correct the problem. Close the offending program and see if you can download an update to the offending program that will agree with Vista. Alternatively, you can set the program to run in compatibility mode set to whichever version of Windows the program was designed for.
Once you've cured the problem or quit the program, you need to go back in and tell Vista that it's okay to display Aero Glass again.
Right-click an empty spot on the desktop and choose Personalize. Then click the Window Color and Appearance link.
Vista will show you one of two dialog boxes.
If you see the Appearance Settings dialog box, select Windows Aero and then click OK.
Once you've done this, repeat Step 1 and then continue to Step 3.
When you see the Window Color and Appearance dialog box, check the box marked Enable Transparency and click OK.
X out of the Personalize Appearance and Sounds dialog box.
Your display should be back to normal.
