I’ve had this question a few times, and I’ve answered it as part of other tips, but I thought I’d respond to it as a stand-alone quick tip. “If I uninstall W10 to revert back to W7/8, can I upgrade to W10 again for free before 7/16?’
The short answer is yes. I actually had to do that myself once. Within the first 30 days of upgrading to Windows 10, you can choose to go back to to our previous operating system. You can then later choose to upgrade to Windows 10 again.
However if you decide to do a clean install of another OS over Windows 10, you will lose all of those files.
