I don't think customers running windows 10 actually know that a build upgrade is actually a new version of windows each time. Unlike previous versions it's not just an update but the core o/s stays the same. People are already bad at backup, but now every 6 months they are at risk of losing everything to a failed build upgrade. I have several occasions where the upgrade failed and the user profile is nowhere to be found having to resort to R-studio data recovery software to recover it. So now it is even more important then ever to have good backups because if ransomware doesn't get you, then a build upgrade probably will.
I would like to say windows 7 will be the last windows I ever use, but I know it won't be. My main pc at home is still windows 7 but it is a 2nd gen intel I5 and in need of an upgrade soon so will have to eventually bite the bullet and upgrade to 10. I wouldn't mind switching to Apple, but I'm not going to overpay for hardware I can't fix myself because they have it locked down so tight. Ok that's my little rant before I start my weekend.
