Most of my students in Xavier Technical Training Center always ask me how they could maintain their computer running smoothly, and prevent the downtime on their units. Some of them were asking how they could prevent others who also use their laptop or desktop computers from changing any settings on it, installing some programs they don't want for example. In computer maintenance solution, aside from Group Policy Editor in Windows operating system, I recommend to them to use a third party program called "Deep Freeze". Deep Freeze is made by Faronics which when installed, Freeze the current system. In other words, if your computer will be "Deep Freeze", no changes will happen on the partition it will freeze. No changes means no users could install or uninstall software, Save, Delete any files even if that files is a bootable or program files. So your computer and your files save on it are safe.
If you will use Deep Freeze especially in a computer shop, you don't need to install any anti-virus. It will be useless because as I said, when you Deep Freeze, any changes made on your computer will be revert to its current state after it will be reboot. Just Make sure you have back up your system before applying the Deep Freeze. This back up could be done either on Disk Imaging or Disk Cloning.

This is because they don't need to save anything on each units and it will be easy for them if they freeze the whole computer so they will have less monitoring on their client moves on each unit. Also, Daily maintenance will be lessen. For those who will use Deep Freeze on their personal computers, I advise them to create another partition from their hard disk drive. Then during the installation of deep freeze, just select the system partition. Leaving the other partition. This will allow the computer user to save their important files because only the system drive is freeze.
