Fix Personalization Control Panel Error

Error: When accessing personalization in windows vista, it says, "Personalization control panel error," 

When i go to personalization in windows vista, it says, "Personalization control panel error,"  and below that, it says, "there was a problem loading a pre-set color."

Why do you think this happens? How can i fix it?

The exact solution is possible only after knowing How are you trying to access Personalization? Does this happen when you try to access Personalization from desktop or from Control panel. If this happens when you are accessing from Desktop, you have to try from the Control Panel. And if it is otherwise, try the other other option if you are still getting the problem.

And if you make any recent changes to the computer prior to this issue, the simple fix would be to use system restore to restore your computer to a much earlier date and try if that works.

If you are still stuck some where, You can try the following steps and check.

Step 1: You can try running the Windows Aero Fixit and check if it helps:
