Activate Windows 11 & 10 for Free — 2026

The watermark that never leaves

An unactivated Windows installation works, but nags you forever: the "Activate Windows — Go to Settings to activate Windows" watermark sits on your desktop, personalization is locked (no wallpaper, colors or themes), and a notification keeps pushing you to buy a key.

Microsoft's own volume-activation technology, KMS, is the shortcut companies use to activate entire offices without typing keys one by one. KMSPico brings that same mechanism to your PC.

One click, watermark gone

The activator installs a local KMS server on your computer. Windows connects to it, validates as a volume-licensed copy, and immediately: the watermark disappears, personalization unlocks, and the system reports itself as activated with a digital license.

A small background task renews the activation automatically every 180 days, so Windows never falls back to the unactivated state.

Step by step

• Download the package above and extract with the password 123456.
• Pause the antivirus for a couple of minutes (every activator triggers a false positive — expected behavior).
• Right-click KMSPico → Run as administrator.
• Press the red button and wait for the confirmation. Check the desktop — the watermark is gone.
