JohnC, since I don't follow the Windows 10 forum, though intend on asking the question there, I don't know yet how widespread this is at the time, if it shipped with the latest version, or anything other than I found an answer that allows to check TRIM on ReFS. Yet go to the bottom of this page & note all 10 NTFS features offered that ReFS doesn't.
For now, the 2nd set of commands was how I was able to enable TRIM support for ReFS in W10.
I may just roll that PC (Dell Optiplex 780 Desktop Edition) back to W7 until EOL with the last backup image taken (after a secure erase of the SSD) & then install the current Linux Mint LTS on it, don't care for these experimental file systems, and the SSD is a Samsung 840 Pro, back when these were more expensive than now & with half the warranty support (5 years) over the 850 Pro, which I'm running on this very PC.

I'll deal with the rest of my W10 installs one at a time when I boot into these, if the ReFS is on there, will roll back to the previous OS. The folks at Microsoft are pure idiotic, here they are losing customers, have for the first time in at least 15 years dropping below 90% usershare, and here comes along an unproven leader that doesn't know jack crap, yet putting his hands on everything (to include purchasing a top seat with the Linux Foundation). Until he was named as successor to Steve Ballmer, only those at Microsoft knew of Satya Nadella. The raw numbers suggests that Steve Ballmer was a better leader, and at least Linux users knew where he stood, Ballmer never retracted his statement & stood his ground. Nadella seems to be hopping on the latest trend of the moment, and thankfully so for Linux users, as we've made huge gains since he's been at the helm of Microsoft & it's only just begun.
Come EOL for W7 (still by far Microsoft's most popular OS), many will have a decision to make. I suspect that a fair share will defect to Linux & Mac, because they could have had W10 for free & refused acceptance. In fact, there's still a back door open for those that needs 'assistive technologies' to upgrade, and it even says on the bottom of the page in fine print that the need for these technologies are not required.
Under the 3rd FAQ's asked:
We are not restricting the free upgrade offer to specific assistive technologies. If you use assistive technology on Windows, you are eligible for the free upgrade offer.
It's a desperation move on the part of Microsoft, for best experience, one needs to use IE for the download, if desired. Link didn't work with Google Chrome for me.
Yet what good is this if they're going to screw their customers over time & time again?
While I'm not a Puppy Linux expert, would rather learn it than run W10 as my daily OS, if Linux Mint were to fold, though feel that I'm safe for a while, when the founder walks away, someone hand picked by him will take over. Still, I use FatDog64 to diagnose computers, because it loads very fast & can diagnose 64 bit hardware in a matter of minutes.
Faster than any OS that I've ever ran, even on slow or low spec hardware, as long as it's 64 bit.
