Windows 10 has reached end of life, but you can continue using it by enrolling your PC into the ESU program for free.
Windows 10 support ended on Tuesday, October 14. That means Windows 10 PCs will no longer receive security updates ...
You can choose to upgrade to Windows 11 for free if your computer is compatible. You can buy a new PC that already has Windows 11 pre-installed (or opt for an alternative, like a Mac or a Chromebook).
