Nastavit System restore avtomatsko?

Kako bi lahko WinXP System restore nastavil da bi avtomatsko naredil ob zagonu ali zaustavitvi sistema Undo restore? Se pravi povrnil v stanje Restore pointa ko bi ga določil kot referenco na nek dan in uro.

To da bi imel vsakokrat ko prižgem isti PC. Iščem simpel varijanto za restor sistema na prvotno stanje. PC je za shared users. V enem postu sem vprašal drugače ampak ne zanimajo me plačani programi in hardverske nadgradnje.

Zasledil sem nekaj na enem forumu iz leta 95:

Auto-restore After Reboot is what ShadowUser does.
By putting the system into ShadowMode, the original system state is preserved. If you reboot without committing changes, then the system will revert to the preserved state.
To further clarify, when running in ShadowMode, all changes are actually written to the ShadowMode cache which is on the free space on the volume. So a restore doesn't copy any information back to the volume, it just uses the original volume information that never changed.

Samo ne vem kako si s tem pomagat. Pravzaprav moram še naštudirat za kaj se gre.
Hvala za namig Windows SteadyState, bom preštudiral.
