The announcement earlier this year the Windows would be giving free upgrades of Windows 10 to Windows 7 and 8 users, sparked my interest enough to download the preview on two of my machines. I was weary if I should back them prior, so I decided to update my laptop first then after a few updated I upgraded my main computer. Don’t get me wrong, there is still a chance something may go wrong so always back up.
Yesterday the Windows blog gave a release date of June 29 for the actual free upgrade and not just a preview.
