I have never been able to install KB 2919355 on my Windows 8.1 system. Contacting MSFT has only been frustrating as they want to charge me money to install their update. I currently have 8.1 installed. My solution is to downgrade to 8.0, and then upgrade to 8.1, which already has the 8.1 Update in it. All that being said, what do you think is the best way to get back to 8.0? I have already backed the system up. Should I format the hard drive with a win 7 disk, and then install win 8.0 on top of it? Or if I use the 8.0 media, will it install 8.0 over 8.1? Just looking for a process here that someone knows will work. The point of all this is that the free upgrade to Win 10 is not eligible if you don't have 8.1 Update installed.
Thanks for any help!
