Schools often use this program to keep information and other student's property safe, and removing it would be ill-advised.
nice software

This is part of the DeepFreeze software that communicates to the server it's status, for example if the software is in a thawed state (any changes can be made), frozen state (no changes will be saved when computer reboots), offline (powered down or not communicating) or updating windows. These are typicially installed on educational/government places but can be installed in large corporations that does not want to have users installing/saving onto the main hard drive. I don't believe there is a home user version so if you have it on your computer, it's either a work computer or one you purchased from a second hand place. If the latter, I would recommend a complete install.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time.
