Day 4 with W10.
Stability in general is good. Have had a few issues with Edge hanging on some sites, seems to be always to do with embedded videos. Which is funny, as some things that didn't go well in IE11 on W7 work fine in Edge on W10 and vice versa.
On the downgrade, I read you have 30 days from upgrade to perform this if you wish to go back. But I don't see any reason to realistically, people who say I don't like the UI experience should try driving European cars for a change with the control stalks reversed
