Glancing back, I've posted a few things about Windows Vista. Haven't said much about Windows 7 (which was an awesome OS, still using it at work). Now here comes Windows 10.
First impressions:
1) Takes an outrageous amount of time to upgrade 8.1 to 10 (both with access to high speed WiFi connection). Tablet took around 4 hours. Brand new laptop, only 10 minutes out of the box took most of 6 hours (and a dozen reboots, but I sort of quit counting).
2) Upgrade breaks stuff, even though both devices were OK's for an upgrade. On the tablet it took another 30 minutes to get the Mail, Start menu and desktop back to an usable state. The laptop's touch pad stopped working and had to download a new drive from the Toshiba web site.
Not "deal breakers" but more an annoyance. I was reminded that the times involved were much better than previous Microsoft upgrade experiences (Win 3.1 to Win 95, Win 95 or 98 to Windows ME, etc). Point taken.
