Aside from these basic limitations, your Windows 10 system will continue to work forever.

There are no nag prompts aside from the watermark, you’ll get all the system updates, and everything else is completely functional.

However, an unactivated version of Windows 10 doesn’t have many restrictions.

With Windows XP, Microsoft actually used Windows Genuine Advantage (WGA) to disable access to your computer.

In the Store, you can purchase an official Windows license that will activate your PC.

The Home version of Windows 10 costs $120, while the Pro version costs $200.

It’ll keep working for the foreseeable future, with only a few small cosmetic restrictions.
