Word of warning, I forced a download of 1709 which I believe is the fall creators update. After doing so my fan control software Corsair 4 stop showing my system temps and the status of all my fans. I called Corsair but they were no help after two calls. At one point as I tried to diagnose my problem i got in to a routine of re booting my machine but with every reboot more and more problems appeared. It finally stop booting into windows. When I did some DOS commands for DIR I could not get drive C: to appear. It appeared as drive X: and could not figure out what to do so I reloaded my original Win10 pro. After a week of reloading my files and all of the associated downloads my system appears to be stable again and Corsair is running as it should. I have to say that I am deathly afraid of my system downloading the Fall creators update as I don't want to spend all that time once again reloading everything. How can I make sure my system does not download and install 1709?
