A funny thing just happened to me on my way to Windows 10!
Not sure if I mentioned this but I actually blew up the first Acer N4620g ( I think it was ESD when I refitted a disk:mad: )! Then, like a real sucker, I went and bought another one because I need to do some experiments with online digital photo storage - but that had a WIN 7 Pro key (when I finally got it out of the supplier, and that's a story in itself!) but no actual OS installed.
After a lot of wasted time (loaded from non-SP1 disk, and it really did not want to fully update and kept reverting to the original installation level - so finally had to load all the 200+ updates in batches of 10 after WSUS offline update did not want to play ball) I eventually got 7 Pro installed and running steadily today. So I then decided to try to upgrade it to 10 Pro - on the assumption that I would have to use the "assistive technologies" workaround to get it activated. However, after a long and protracted automated installation procedure (from a USB key) it all loaded up and so I had a look at the Activation tab in Control Panel Systems - and it tells me that it IS already activated without me doing anything!
Wonder how long this will last, has someone been giving duff info on the need to use the workaround - or has Microsoft finally, but quietly, made the upgrade free and without strings? (And I also noticed that there are a huge number of WIN 10 licences available on ebay - and probably elsewhere - for only a few quid).
