Hi, folks: Up until mid of last year, I used FD-ISR ; two different sanpshots with different security setups, and it worked very well for me. And later of that year, I uninstalled FD-ISR, replaced it w/ DeepFreeze, it works very well for me too. Now, I am contemplating an idea to pair them up. I like DF-ISR being able to provide me two different setups(just like having two PCs) and DF being able to supply me a solid sense of security. Has someone had similiar experience and like share it w/ us? (any virtualization app, such power shadow or shadowuser etc?). Any downside do you know? Thanks.
