If the windows10 anniversary update is still giving you a headache please go on reading... Somehow the windows10 anniversary build didn't work out for me on an older machine. (my GPU was no longer detected) So I was more than happy to use the windows roll back feature to a previous build. (btw rolling back to a previous build only works for 10-30 days,after that you need to reinstall the 1511 build) Still, soon after rolling back, windows started the update once again and I would be ending in an unfortunate endless loop. In trying to stop windows from trying to update my 1511 edition to the windows 10 anniversary build, I finally found a small but effective reg tweak. Although originally meant for preview builds it seems to work for the regular builds too. (So far so good) Check it out over here: htttp://winaero.com/blog/how-to-prevent-windows-10-from-installing-a-new-build-automatically/ A special thanks goes to Sergey Tkachenko. Hope that someday this might still help someone. Take care.
