Microsoft kindly installed Windows 10 on my computer on night, I had Windows 7 with which I was happy! With the Windows 10 surprise installation, not knowing how to correct it, I stuck with it, my big mistake, Windows 10 is dreadful, Windows Live mail was gone, Edge does not allow other toolbars, getting program icons on my desktop is now impossible, w10 wants them all on the task bar. Now the system is asking for Windows’ 10 to be ACTIVATED, I found the activation finally in settings, but windows did not activate, asking for Activation Key, which I did not have, nor ever had. So whereas the Windows 10 anniversary update is asking to be installed, the system refuses to be activated. Where do I get an activation key for software Microsoft installed without my actual permission, and which I am now stuck with! Microsoft themselves are NOT helpful at all!
