XP USER Account Restrictions

Hello,

I've set-up a new account that's under the "Limited account" type so guest users can log in without my worrries that they'll mess up my configurations and settings. Problem is, after creating the new account, I tried loggin it to it, and found out I could still access the registry and install some programs. I mean I don't know how my brothers and sisters do it but they manage to fubar my desktop on a regular basis! So I created them their own account with limited rights. So

1) Isn't there a way for me to log onto their account and from there log in as admin to make system changes? Or could I set restrictions to their accounts ONLY via my own admin account?

2) I'm toying with GPEDIT.MSC because I want them to have VERY limited access to most things, I.E. desktop settings, taskbar changes, all programs except their games, etc.

Because I couldn't figure out question 1, I change their accounts to admins so I could run gpedit from their logon thinking the changes I made to the "user configuration" would only affect the user that gpedit was running under (in this case the Kids' acct).

Well, I disabled MANY things like the run comand or the folder options and control panel but then when I logged in to my own account the same restrictions applied to me too!

Jam it back in, in the dark.

Thank Duminas, Yup I have recovered from the restrictions I set on myself. While your tip on the registry restriction is handy, its just one ofthe hundred settings I'd like to control... I dont think I have the time to set up that Active Directory stuff...

There's nowhere I can't reach.
