if you folks liked the Anniversary update (it caused more than a few headaches for Home users, as well as PRO who did the update) be forewarned in a few weeks the lastest major update Windows (10) Creators is coming.
I was bit in the ar$e by the Anniversary update (as was my wife) on our laptops. I had too much work to do to troubleshoot it, so I upgraded mine back to Windows 7.

I was able to get my wife's to finally boot up by using an Acronis Image I had luckily done prior to the Anniversary update), and then when it got applied again, it worked (my guess is the first time was buggy). But all she uses is Microsoft Office and Firefox.
I could have done the same on mine, but I would still have had to re-install a bunch of applications, many of which require authentication that doesn't take between OS upgradees (as I found out when I first upgraded my laptop to Windows 10), so I just went back to Windows 7 for now. I've re-installed everything, and I have a basic Windows 10 image I can use; however, I think I'll wait for the "Creators" update to happen, then download the ISO image, and then try the update on a clean system (since I got mine updated during the free cycle, they already have my credentials for my machine, and I can easily go back and forth between Win7 and Win10 with no consequence.
Interestingly, my HP desktop (even though old) has done just fine with Windows 10.
