In October 2025, Microsoft officially ended free support for Windows 10. No more monthly security patches, no more fixes for newly discovered flaws. The machine on your desk still boots up, still runs your programs, still opens your bank statements — but the safety net underneath it quietly disappeared.
That matters more than most people realize. Every month that passes, attackers catalog new vulnerabilities that will never be patched. Unsupported systems become the easiest targets on the internet, and the people most affected are ordinary households running perfectly capable five- or six-year-old computers.
The obvious answer — buy a new Windows 11 PC — is also the expensive one. A capable replacement runs $800 to $1,200, and that is before you spend a weekend moving files, reinstalling software, and relearning where everything lives. Throwing away a working computer to solve a software problem is, frankly, a waste of money.
This is where PrimeDefender fits in. It is not an emergency shield bolted onto a dying machine. It is a bridge: a modern security layer that handles the things Windows 10 no longer does for you — credential leaks, phishing, tracking, unsecured networks — so your existing hardware stays useful and protected for years longer.
