The release of Windows 10 is just two days away! It looks like Microsoft is fully focused on delivering the new operating system, as the company silenced on the new announcements in the last couple of days. But alternative sources, like famous Russian leaker WZor, still have some info about Windows 10 for us.

Namely, Wzor (whose information and leaks are mostly true) reported that you’ll be able to install and test Windows 10 even if you don’t have a license key, but only for a specific amount of time.

You probably already know that, if you’re using genuine copy of Windows 7 or Windows 8.x, you’ll be able to upgrade your current system to Windows 10 for free. But what to do if you want to install Windows 10 from scratch, or you’re using some older OS, like Windows XP? Although Microsoft didn’t confirm anything yet, it looks like it will release Windows 10 ISO files for this purpose, and as we mentioned, you won’t need a product key to install it.

Wzor posted Windows 10 release notes on Twitter a couple of days ago, and according to those notes, you’ll be able to install and run the OS without immediately needing a product key. Of course your copy of Windows 10 won’t be genuine, but it won’t affect the performance and usability of the system. But, you will have to eventually enter a product key after a specific amount of time.

If you want to install Windows 10 on the PC that already has ‘upgrade-valid’ versions of Windows, the OS will be activated automatically. But, you’ll only be able to upgrade to the same version of the system, for example Windows 7 Home/Windows 8.1 – Windows 10 Home, and Windows 7 Professional/Windows 8.1 Pro – Windows 10 Pro.
