Microsoft made a few quiet but great changes to its kid-proofing SteadyState tool for Windows 7, changing the name to Guest Mode
This nearly-hidden feature called Guest Mode that is primarily aimed at shared consumer PCs that need to be returned to their original running state after being used by a child or guest. The feature can be enabled on individual user accounts; when user logs off or the PC reboots, those accounts are wiped clean and returned to their original configuration. Guest Mode is useful for small classrooms, libraries, and other shared computing scenarios, but is really designed for home use, where parents may want to configure the feature for their children.
Guest Mode was originally called PC Safeguard. Its features:
-Prevents system setting changes. Any attempts to change the system while running under a safeguarded account are prevented.
-Prevents the installation of applications and other software. Once you've enabled Guest Mode, it is impossible to install or permanently configure already installed software applications.
-Prevents the user from writing to the disk outside of their user profile.
-Data saved inside of the user profile is deleted when the user logs off.
To find Guest Mode, open Control Panel, User Accounts and Family Safety, and then User Accounts. (Shortcut: Open the Start Menu and click your logon picture in the top right.) Then, click on Manage another account. From the list shown there, select the account for which you'd like to add Guest Mode. Or, if you don't have an account for this purpose, create one first.
