Windows 10 updated my desktop computer without my permission and installed its browser Edge which will not open. I have to redirect everything to Internet Explorer. Edge is a joke, as is 10.
Be sure to disable Cortana or you will have the Start button not working and the inability to right click on the program buttons on the taskbar along with the wifi not working.
