Performance Settings Not Being Saved

About two weeks ago Windows 7 (64-bit) stopped remembering my preferred Performance Settings (My Computer > Properties > Advanced System Settings > (Performance) Settings). For example, I want to enable "Animate windows when minimizing and maximizing." I can check this option in the Performance settings, but the duration that Windows will remember this setting is arbitrary.

Sometimes, the setting will be kept until the next time I reboot, but at other times the setting will only be in effect for a random length of time - minutes to hours - before it reverts to being disabled. I cannot determine any specific set of circumstances that might be causing this.

I have tried to gain ownership of the key located here in the Registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects\AnimateMinMax thinking that there may be a permissions problem, but I had no success. I can't take ownership of the key, nor can I change its permissions.

I would greatly appreciate any help that can be offered. Thanks!

It sounds to me like your not Admin of the PC

My user account is an admin account. Should I login to the *real* admin account and make the change from there? Will that even apply to my usual user account?

Here's another question - since I set up my user account to be an admin account, but I can't make changes that an admin would - what is wrong with the account?

If its any consolation, this problem seems to afflict many.

You can try some of the steps suggested in these threads. Also, try updating the graphics driver.

If nothing works, try running an sfc scan or a repair install.
