I had bought a cheap Dell Inspirion touch-screen PC for home, somewhere in the last year. I got it from Best Buy, and it was a “return” unit. It had Windows 8.1 on it, which I was not enamored by. I did note that the unit would often go to the “Blue Screen of Death” and I had thought that the unit probably had some bad memory which was causing this. So, I had left the unit off for months, just sitting there collecting dust.
Then over the weekend, I decided to start it up again, and then it came to me to see if I could get the free Windows 10 upgrade. I found the upgrade request site and put my email address in. At some point the little Window icon appeared on my Task Bar, and when I opened up the window from it, it said that Windows 10 was downloading in the background and it would notify me when I could start the Upgrade process.
Last night, I finally saw that the files had finished downloading and I started the Upgrade to Windows 10 process. I think it took less than an hour, and when it was through I started using Windows 10.
Windows 10 seems to start up quicker, and I have been pleasantly surprised by the interface. Enough like Windows 7, which I still use at work, and yet combining the Windows 8 interface.
ADDENDUM [8/15/15]: I have continued to be happy with Windows 10. I haven’t had a “blue screen of death” since I installed W10. I installed Snagit successfully yesterday. I’ve modified the background screens.
