So I have an interesting problem that a council has presented to our organisation. Libraries and community centres offer computers that are locked down for end users. Lately there has been a trend to offer PCs for creative use which requires the use of PCs with higher levels of access privileges. The council wants to enable users more privileges on these PCs as well as enable them to save files during the session. Then upon reboot / signout the PC would be restored back to an original state and wipe all data. They have tried using system restore but it would seem that it's not always reliable and lacks control. They are looking at software like Deep Freeze, Shadow Defender etc... Anyone here have experience with these two or any others and can recommend. Any pitfalls?
