I am currently finding an alternative to Deepfreeze because a program that i want to use does not work properly if Deepfreeze is installed. So someone suggested Shadow Defender. So far i like it. my program that is not working properly on DF works fine with SD. BUT why does my OS (XP) show the improper shutdown menu when i Hard reset/shutdown my PC? In Deepfreeze when i do the same thing. there is no improper shutdown menu, as if nothing has happened... I am now thinking Shadow Defender MAY not be as ROCK SOLID as Deepfreeze. And I am afraid that in a couple of months, with "many" improper shutdown my OS or my Primary partition will be corrupted. SD will be installed (as soon as i am sure if it is as ROCK solid as DF) on an internet cafe so i am expecting around 5-10 hard reset/shutdown per day... so far with Deepfreeze there has been NO problem... comments?
