My friends have you heard of deep freeze? It is a software the helps eliminate PC damages as what the site claim. What it meant that its going to protect your computer no matter what by restarting to a former working state. It reboots to how you configured your computer and any new files or programs installed the "Freeze mode" computer would be automatically deleted the next reboot. Many internet cafes here uses this program but this concerns me.. Does it really protect the PCs? I mean if it does protect them then why do they always do reformats and some internet cafes I've been with some units crash into blue screen or most. Does deep freeze take up memory space?
