Windows 7: "Fade or slide menus into view" fails to save on non-Administrator

I am running Windows 7 Home Premium 64-bit on my laptop and Windows 7 Ultimate 64-bit on my desktop. I have two user accounts on each: one Administrator account and one User account that I have for everyday use. I am experiencing this issue with both computers.

The issue I am getting is that, on the User account only, the "Fade or slide menus into view" checkbox in the "Advanced System Settings" window fails to save after I log out or reboot. The state of the checkbox is saved on the Administrator account though. I have followed the "manual" portion of this guide using regedit.exe in both elevated and standard modes. The "MenuShowDelay" registry key is set to "5" (which is the number I chose per the tutorial) in both elevated and standard modes of regedit.exe even after a reboot (this indicates the registry is not being overwritten or reverted after I change it).

I am currently at a loss about where to proceed from here. I wouldn't be surprised if this is a really stupid and petty fix, but I'm really out of ideas...

EDIT: I guess I should add that this seems to be affecting most (if not, all) of the checkboxes in the "Advanced System Settings" window and not just the one.

Start with this link and see if that helps.

I mentioned in the OP that I have already done the "manual" portion of that tutorial.
