I'm at my wits end with this issue... I heard the news of a big Win10 update hitting soon and I wanted to check if I had it already. To my surprise, my system last update was the 6th of October... odd. I'm using Windows 10 Pro x64.
Error 0x80080005! I've looked what that means and it's something related to Windows unable to access some files, but I don't know what files. The same happens when using the Windows Store, I can't install anything and I just realized that because I never use the Store.
I also tried the solution given in this post with no success.
I don't know what else could I try, please help me. :(
