I mentioned in another thread that I liked and had recently bought Acronis True Image 2016 Cloud, and mentioned: "The only trouble I've with it is that it can get somehow "stuck" on backups and never complete them. Fixing this requires ending processes and rebooting. But I had similar problems with a couple of other options I did trials of, so I'm guessing it's a conflict with something else I have installed rather than a "bug" in Acronis."
I was asked to start this thread by another user who wanted to troubleshoot the problem. I really am not sure it's Acronis - I'm finding Windows 10 to be very unstable, randomly losing control over various components so that I have to reboot several times a day. Hanging on updates and restarts and installations.
