Took the initial version and had some issues with the start menu not working and neither did the the Cortana search box, which made opening up applications a little tricky.
Also some browser issues.
Lots of gnashing of teeth for a while – a powershell script that I found (had no real idea what it was doing, just followed instructions) seemed to work, but then was undone by a further windows 10 update that was rolled out. At this point the script didn’t seem to run and it was beyond the 30 day period that you could roll back so all the files had been deleted.
With a bit more time, MS seemed to fix some of the bugs and more solutions were available online as a experience grew.
Seems OK now, not significantly faster boot up times but I am running it on an old laptop, which is the constraining factor. I’m probably putting this in the early adopter glitch rather than fundamental issue…
