Prepare computers for mom to use

I spent some time to set up my laptop computer so that my mom can use it anywhere she wants in the house during her one month staying. I set up an account for her, change the user interface so that everything is display in big Traditional Chinese characters, and then have a Traditional Chinese version of portable Firefox set up with her email account and some Chinese newspaper web site so that she can access them at ease. I also installed Ad Block Plus and NoScript in order to minimize her possibility of getting virus or spyware attact. And for the worst case scenario, I have the boot partition backup so that I can wipe the whole machine up and restore the system at ease.

However, I also realize that when I am not at home, my mom may enjoy using my desktop computer with a 24 inch and 20 inch monitor instead of looking at the 13 inch laptop screen. Problem is that there's a lot of important information that I stored on my desktop, and I don't know my mom to have them accidentally wipeout.

And that was the time when I realized that the Group Policy mechanism provided by Windows 7 does not give me an option to hide and block certain drive for certain specific user. Luckily, there is still a way to prevent my mom from accidentally messing things up. All I need to do is select property of each drive. Under the Security tab, I put in my mom's user name, and then deny her access on that drive.
