The legitimate way to remove the “Activate Windows” watermark is to activate Windows with a valid digital license or product key. Do not use Registry hacks, scripts, KMS emulators, or activation-crack utilities to hide the watermark without a valid license.
Check activation status
- Open Settings.
- Select Update & Security.
- Choose Activation.
- Read the Windows edition and activation status.
If the PC should already be licensed
A hardware change, edition mismatch, or account/licensing problem can prevent activation. Use the Activation troubleshooter when Windows provides it, and sign in with the Microsoft account associated with a digital license when applicable.
If you have a product key
Use Change product key on the Activation page and enter the legitimate 25-character key. The key must correspond to an edition it can activate.
Avoid watermark-removal utilities
Tools that promise to remove activation messages without licensing Windows can modify system files or licensing services and may contain unwanted or malicious software. They also do not create a legitimate Windows license.
Windows 10 normal support ended October 14, 2025. Activating an existing installation may still be necessary, but activation does not restore normal security support.
