Deleting unnecessary files of all the local users

[Bickyz]

I have a network with 1 w2k server and 20 w2kp clients. All the users are students. All the users login to system using local user accounts of each pc. The username are userpc01, userpc02, userpc03........userpc20. So basically these users doesnt login to domain. All users has created several files and saved in local hard drive of each pc, now i want to delete all these files coz its not needed anymore. These users has saved their files in following locations of each pc:
-Desktop
-My Documents

Now is there any script or easiest way of deleting these files rather than me going to each pc, login and deleting one-by-one.

Would there be a problem if you deleted the profile of the local users? That might be the simplest solution.
