... Your computer will search/download for Windows 10 even if your computer has been off a month! ...
Indeed it will, and take about a month doing it . . . well, ok, several hours during which time the computer is almost completely useless

I have an old Windows 7 laptop which I use very little. Switching on after a week or so I found it was very slow so I checked the resource monitor which showed 98-100% CPU time devoted to Windows Update services. Having discovered that cancelling only meant that it started again . . . from the beginning, I left it to play with itself and went to bed. On checking the Windows log in the morning I found it had finally finished around 1-30am, and it told me there were updates ready to download, so after all that time it hadn't even downloaded them apparently

I daresay the MS terms and conditions allow them to update/upgrade your system so I assume, like Brian, we'll all eventually have Windows 10 whether or not we asked for it. I actually rather like it once I've disabled all the 'special features' but I sometimes wonder if even that will be overridden in the future and we'll be forced to use Edge, Mail, Cortana, etc. When that day comes I will most likely switch permanently to Linux
