Yeah, different answers for sure. In one respect, a response like that could indicate that those who maintain and take care of their computers to ensure no problems arise would run those commands regularly. On the flip side, I am an avid enthusiast and IT professional with many years of experience...so I really take care of my computers as well, and I find no need to run these types of commands regularly. So, I don't feel my lack of running these commands indicates in any way that I am not managing my computer.
i take images from time to time as well of my machine. But I never have problems with Windows updates, so I don't do images regularly before an update. i can understand why some may want to do these types of proactive backups, but my experience with updates has been quite smooth.
