I just did a test with the Live CD that I had downloaded
When logged in as "school", I attempted to open some of the partitions. Each time it asked for the root password. If I used the school password it didn't allow me to view the partition. However, if I used the root password, I could view just that partition.
If I logged out to the login stage, then the root privilege was retained and I was able to view that partition. It placed a little school symbol in green next to the directory list under the file manager.
I then rebooted and tried the test again but this time, when I opened the file manager and attempted to open one of the other partitions, I only used the school password. The system didn't allow me to view the partition.
BTW I don't have windows on my machine at all - just PCLinuxOS 2011.06 KDE
I am not sure if my testing above helps with your research. I did hear this morning that the grandchildren spent all last Sunday on the Education package. By the time they had finished, they had accumulated so many penguins across the bottom of the screen that their father had to come and photograph the screen for them. (They were working just from the Live CD so not installed).
Kind regards,
Jim
