Undo your worries with Windows Disk Protection
Windows Disk Protection keeps everything on the Windows disk partition from being permanently changed by users. This means every change made during a user session can easily be undone and the computer returned to its original state.
Create a consistent experience
On a shared computer, the goal is to create a consistent, uniform environment for all users. They should not be able to modify or corrupt the system. However, activities performed during a user session cause many changes to the operating system partition. Program files are created, modified, and deleted. The operating system also updates system information as part of its normal operation.
Windows Disk Protection clears all changes to the operating system partition whenever you restart the computer—or at whatever interval you specify.
How Windows Disk Protection works
When disk protection is turned on, it creates a cache file to retain all the modifications to the operating system or program directories. Histories, saved files, and logs are all stored in this cache file which has been created on a special partition of the system drive. At intervals you designate, Windows SteadyState deletes the contents of the cache and restores the system to the state in which disk protection was first turned on.
Set it and forget it
Choose the disk protection level that fits how your computer is used and whether or not your users need to save data for a specific length of time.
