Seize Thy Os

Restoring computer to an original state that was before the fresh install of Windows is one of the worst and most tiring jobs I ever came across. I tried from making an image of my boot partition from another OS(HBCD or some more), to making backups, to making restores. But the saviour I at last found was so good and simplistic in approach that I am not able to believe it even now. Its a mere 6 MB download and it works magic. Every bit of this paid software feels paid back if you really are sick of your cyber-cafe or any computer crashing and getting viruses from other people's use. I don't want you to download it from here! ;-) This is faronics' official website. And the software is called deep freeze. It is one of the best software I've ever seen in the field of computer restoration a mere 6 MB download and it works as magic.
WIKI:

"Deep Freeze is a kernel-level driver that protects hard drive integrity by redirecting information being written to the hard drive or partition, leaving the original data intact. This redirected information is no longer referenced once the computer is restarted, thus restoring the system to its original state at the disk sector level. This allows users to make 'virtual' changes to the system, giving them the appearance that they can modify core files or even delete them, and even make the system unusable to themselves, but upon reboot the originally configured 'frozen' state of the operating system is restored."

Or in human language: it brings your computer to a steady state (you defined before), every time the computer is restarted.

*Just a warning, it shows up in the system tray and if you want to open the admin window double click the window while holding down shift.
