So i have to start saying i'm a 17yo girl, not a very experienced user, nor a native speaker, so please be gentle. Having read all different kinds of reviews about DeepFreeze, ATI etc.. i don't quite know which one would do the best job for me.. I soon have to reinstall my XP-again- and i'm so not looking forward to it that i decided to do something to prevent that from happening in the future.. Now most of the apps have powerful tools and all, but i'm a humble user let's say, with minimum requirements.. I would like to keep my primary partition, c:\ -with all the programs (and configs) i frequently use already installed- and get back to that fresh state when it all becomes slow and messy.. Deep Freeze seemed pretty interesting but i do tend to install little programs quite often, so i'm looking for the easiest and fastest way to 'defreeze' the system, preferably without rebooting. Also, which is the easiest way to resize c:\ without losing any data from the partitions and what would be the recommended size, given the 500+80 HDD? And probably my last question- Is it possible to hide entire partitions from other users(with limited accounts) without having to lock and unlock them everytime i need to access the files? I would greatly appreciate it if you could answer my questions, and i'll keep reading tutorials so i can make something of your awaited answers.
