How to clear up space in System C:?

[snelso28]

Hi, I haven't been using System C: to store any files, but for some reason it's almost full and is affecting my use of programs. Anyone know what I should do to fix it?

Unfortunately, an administrator must resolve it manually by deleting user profiles that have been copied to the machine for quicker login times. If you come across a full C:/ drive, please submit a problem report noting such and please ensure the computer name is correct so that we may resolve it.
