"My computer was working great last night [but] this morning it says, 'Microsoft Legal Agreement' with bunch of legal information and WAY at the bottom 'Accept your new Windows 10' or 'Decline,'" wrote a someone identified as scifixtion in a Friday post to Microsoft's support forum. "I hit Decline and it says, 'It will take a few moments to go back to your old Windows software,' [but] then it goes black and go[es] right back to [the] Microsoft legal agreement [and shows] 'Accept windows 10' or 'Decline.' I've hit Decline a dozen times and it won't budge."
The legal agreement that scifixtion referenced was the Windows 10 end-user license agreement, or EULA.
