I got lucky and managed to get hold of one of the last "genuine" Fd_ISR last year. I am very happy with this program and would not want to be without it on my own prime pc. There are a few other pc (all XP) that I use and I would like to install a similar program on these. The main purpose of this would be able to install software and software updates (like XP3) and evaluate if they cause any issues. I know that rescue software also has security/ malware implications but as these other pc are not heavily used, that is not a big issue. Also, while I love the multiple snapshots and particularly archives in the original Fd_ISR version, for these pc I don't need this. What is required though is a reboot ability, so programs like Returnil won't be useful. Simply put, I would be happy with a System Restore that actually worked. I know that there are many threads touching on this subject but doing a search right now, I could not find what I was looking for. I suspect some of the relevant issue is hidden in some of the super threads with 300 postings.
