Just as an aside ... 12 months ago I upgraded to Windows 10 from Windows 7 64, and W 10 refused to work properly for weeks ... contacted Microsoft and spent hours with them trying to resolve ... they eventually accepted defeat..... they admitted upgrades
were not always successful and they would return me to W 7.
This they also tried, but as they could not recognise W 7 Product Code attached to my PC ( despite emailing a photograph to them) this meant a download to USB stick ( on another computer ) and a re-installation of W 7.... which then worked !
So now I can't re-install W7, as I have no Product Code that works on either .. and have error code 80248015 which still isn't, or looks like being, corrected.
Not going to Windows 10 to only get the same problems, can't update anything on Windows 7 ... where next ... Apple ?
