With Windows 10, Microsoft made it quite easy for interested users to receive beta versions of the operating system. This works out in its favor, as it lets those on the cutting edge get new features as soon as they're released. In return, Microsoft gets to test new developments with a big group of guinea pigs.

Of course, not all is perfect in Insider land. Microsoft isn't giving any Insiders a free copy of Windows 10, and they have to eventually stop supporting old builds. The latter is approaching fast, as Microsoft is beginning to retire old versions that Insiders might have floating around quite soon.

To check if this will affect you, press Windows Key + R to open the versatile Run menu and type the winver command. This will open a simple window containing your currently installed version of Windows. You'll find the friendly version (1607 for the Anniversary update) and the build number.

Right above the This product is licensed under text, you might see something akin to Evaluation copy. Expires 10/31/2016 11:59 PM if you're an Insider. If this expiration date isn't far off, you'll want to head to Settings > Update & Security > Windows Insider Program to check for new builds.

While you'll also see a notification if this affects you, your system will start rebooting as it gets closer. Thus, it's in your best interest to check for sure and update before it becomes a problem.

Getting close to expiration and just updated to the latest version of Windows 10? Watch out for the big Anniversary Update issues and learn how to fix them.
