Heck, some people even use MS-Backup by their own volition...
This is good news. Not only because more people will have patched Win10 until 2026, but also, because now the ESU gets to common folk, more SW companies (specially SW companies that deal with consumer SW) will be incentivized to support their software on ESU.
Remember that until Win7, ESU was restricted only to enterprised, and therefore, only enterprise software companies were incentivized to match the ESU support timelines. More mainstream consumer software was incentivized to drop the old OS shortly after the support for consumers dropped.
BTW, I was(I'm still) gifted with a MS-Office family subscription... That includes a 1TB Drive subscription, may as well activate MS backup (currently I backup to a Synology) and get done with it. At least it will be a different backup path.
