Rollback RX is the best for home/personal use! Bought this laptop with win 8 pre-installed, so Rollback RX wouldn't install, because it is not compatible with GPT on 64 bit. But hey who needs GPT on a PC for personal use? Tried first Deep Freeze but the downsides were 1) Hibernation doesn't work; 2) it can not test and keep at the same time, so first one has to test in frozen state then reinstall in thawed mode. And Shadow Defender's got this big status image at top on desktop and is not so easy as RR to use. Returnil includes scanner etc. of no interest. With Rollback RX you can keep a baseline with first installation and updated drivers. From thereon you can just rollback to last snapshot and do upgrades. It's clean. And there's no need for virus scanner. It works best ofc. if system and features/other apps are kept on separate drives, because then there's only need to rollback when a new driver fails or to update on the latest snapshot. So you have to move programs/data, which has the benefit of keeping the system clean and faster and when you want to ditch the computer you can very easily take the programs/data on to another.
