Feature of Windows Steadystate is disk protection. This can be accessed by clicking the 'Protect the Hard Disk' option on the main screen: use it to wipe out any changes made by users so user accounts start in the same state each time they're accessed. Select the On option, wait for the required cache file to be created and restart when prompted. Now choose between removing changes evelY time Window is restalted or w1til a specific date. Note that disk protection will remove any new documents saved in the My Documents folder, so use it with great care. To avoid this, documents must be stored in a different partition - see the Masterclass in the last issue for more information on partitions.
