I have had a windows7 PC for a couple of years, quite happy with it
I saw on facebook a pal of mine said they upgraded to windows10 in 5 hours, downloading/ sorting out/ everything so I thought I would give it a try
You press a small windows icon bottom right of your screen, this does not upgrade you, it does put you "in the queue" though
To avoid 'the queue' there are guides out there that show you what to do, if you're in a hurry you can just "sort it" yourself allegedly
Anyway, I stayed "in the queue" and within 7 days I noticed a blue 4" x 4" panel appeared by the windows icon saying "COME ON DOWN" well it didn't say that but basically you're UP!!
so from there to Windows 10 it was literally 2 or 3 hours - job done, pretty happy with it AND everytime you start the computer now, you get a choice "WINDOWS7" or "WINDOWS10" so if you don't like it.....
pretty impressed! no mishaps, no errors, no problems
they did a good job !! HOW DID YOU GET ON? (oh and LOGII works fine!!)
