I've been running under Windows 7 for several years now. For at least a year) I've been getting those incessant pop-ups encouraging me to upgrade to Windows 10! Yesterday, I finally relented! Although I wasn't watching the clock, my guess is that it took 2 1/2 to 3 hours before I got a login screen – really not so bad! Except for a few glitches, everything went fairly well. In fact, my perception was that Windows 10 was a little faster! At the end of the day, I shut the system down and went to bed..
the trouble started this morning. When I turned the system on, I got a login prompt. After logging in, the system went to a light blue screen and started blinking. I rebooted the system several times, but never managed to get another login screen! Fortunately, I create a backup of the disc image every night. So, after 3 to 4 hours, I managed to restore the Windows 7 partition!
I was wondering whether I made a mistake trying to upgrade from Windows 7 directly to Windows 10! All of the prompts were telling me that my environment met the requirements. Additionally, until I shut the system down yesterday, the Windows 10 environment appeared to be functioning satisfactorily.
Although I don't do any real work in them, I have both Windows 8.1 and Windows 10 running in virtual machines. Other than adversely affecting performance, neither environment gives me much trouble.
I wouldn't mind upgrading my "production" environment to Windows 10, but I don't know whether I have the fortitude to go through another day like I had today. Did I make a mistake going from 7 directly to 10?
On a side note, I noticed that after installing Windows 10, my APC battery backup started misbehaving.
