Disk Quota Utility in Windows Vista not working

I’ve had this HP Pavilion notebook for about a year. I recently upgraded from Vista Home Basic to Vista Business, although that did not alter the behavior I’m going to describe here.

In the Properties menu on the hard drive, one of the option tabs is “Quota”. When I click on that, it gives a brief description of what disk quotas are and there’s a button you can click on to view or change the quotas. I click on it, and am prompted for admin confirmation which I give. But then, instead of doing anything, it just re-pastes the “Quota” tab window, complete with the button described above. If I click on the button, it simply pastes the window a third time, and this can go on and on until my screen is full, or memory runs out, or whatever.

I used to share this computer with my wife, who recently got her own computer. Therefore I want to be sure that there isn’t an undue amount of disk quota associated with her username. The actual disk space she used was very little.
Has anyone else run into this issue with Windows Vista (or any other version of Windows)?

Don’t worry: in any event, the disk quota is the maximum amount that she can use, not the amount set aside for her.

I’ve got Home Premium and after I pass UAC I get a tab saying Quota Settings for (C:) and various options.

A probable reason is your drive is formatted as FAT32 instead of NTFS. FAT32 does not support disk quotas.

No, this is an NTFS disk.

What do you mean “after you pass UAC”?

Hmmm…

UAC is what prompts you to confirm when you try to access an admin function. It’s a right pain. You are logged in as an admin, aren’t you?

That’s correct. I go through the admin confirmation prompt the first time, after which it just repaints the “Quota” window. If I click the button a second time it just paints it a third time without asking for confirmation.

Clicking that button should bring up a new window. Is the new window possibly hidden behind something else?
