Windows Update and limited account problem?

Well, the problem is it doesn’t work. I’ve checked the settings and they’re set at “download updates for me, but let me choose when to update”. But it doesn’t do that. I have to login on the admin account to make it work.
I don’t get any error messages, it just doesn’t simply work with my limited account.

Ok, maybe it’s not possible to get updates with limited account (I just found some sites saying so, but not why). But is it impossible to fix so that I at least get that popup that there are new updates? If the Antivirus can work (even download and apply updates) why can’t WU work?

I’m running WinXp Pro SP2.

Well, I solved it. Seems in Group Policy (gpedit.msc) you can change a lot about Windows Update. Found a option for exactly my problem.

Now I’ll get a popup at least when there’re updates.
