I cant change window color and things like that anymore?

[Steven10090]

I have Windows Vista Home Premium x64. Instead of letting me customize transparency and color all I can do now is customize message box settings. How can I fix this?

There might be 2 reasons of this. First, either you might have disabled Aero by mistake or Second, Video driver is missing. You can fix it easily. Just click on start menu, type Aero in the search box. You will get results saying "Troubleshoot Video and Transparency" or something like that. Click on It. Click on Troubleshoot. Wait for a minute. It will trouble shoot itself and fix the issue.

If it cannot fix, than it will give your driver error. Simply download the driver and install. Thats it.
