Extract with WinRAR using the password above, then run as administrator. Works on Windows 10, 11, Server & Office.

Windows upgrades and major feature updates (22H2, 23H2, 24H2) can sometimes reset the KMS license token. This is normal and takes under a minute to fix.

2
Re-run KMSPico
Download from this site, add to Defender exclusions, right-click → Run as administrator.

Verify
Run slmgr /xpr — should show expiry date approximately 180 days out.

Why activation drops after an upgrade

It's common for Windows to show as not activated right after a major feature update or an edition upgrade (say Home to Pro). The upgrade can reset the licence binding or leave the old key in place, so Windows momentarily can't match a valid licence. The install is fine — the activation state just needs refreshing.

What to try, in order

  1. Wait and let it self-heal. After a feature update, Windows often re-activates within a day once it re-checks online.
  2. Run the Activation troubleshooter. Settings → System → Activation → Troubleshoot.
  3. Re-apply KMS activation. If the licence was KMS-based, simply run KMSPico again, or repeat the slmgr commands — this re-binds the correct edition key in one step.

If you see a specific code

An upgrade can surface codes like 0xC004F200 (non-genuine) or 0xC004F210 (edition mismatch) — each links to a targeted fix, and the troubleshooting hub ties it together.

An upgrade from Windows 10 to 11 can reset the license state, especially if the hardware fingerprint changes or the edition changes. Re-running KMSPico restores activation instantly.
Sometimes. Feature updates occasionally reset the KMS token. Simply re-run KMSPico or slmgr /ato to restore activation — takes under 30 seconds.
KMS activation is not hardware-tied. Changing RAM, storage, or GPU does not affect KMS activation. Only a complete motherboard replacement may trigger re-activation (which KMSPico handles instantly).
