To clear things up this is what Microsoft states: mis-leading as it does not state what happens after one months time but I think you can go back at anytime and not spreading anything I didnt believe to be true never have and why would I now - relax

 

Can I go back to my old operating system?

Yes, there are a few different ways for you to go back from Windows 10 to a previous version of Windows:

• If it's been less than a month since you've upgraded to Windows 10, you'll be able to go back to your previous version of Windows from Settings > Update & security > Recovery.

• If your PC manufacturer provided the option, you might be able to restore your device to factory settings.

• If options to go back and restore factory settings aren’t available, you can use installation media and a product key to install a previous version of Windows.

 

30 days is how much time you have to revert to W7 or W8.1 if you upgraded. That doesn't mean you have to relinquish your old license. If you want to install W7 after you upgraded and after 30 days, then you can obviously do that.
