How to Remove the "Activate Windows" Watermark

If there's a faint "Activate Windows — Go to Settings to activate Windows" message sitting in the bottom-right corner of your screen, you're not alone — it's one of the most common things people want gone. The good news: it's harmless, it's not a virus, and it disappears the moment Windows is properly activated. This guide explains what the watermark is, why it shows up, and the clean way to remove it for good.

What the watermark actually is

The watermark is simply Windows telling you the copy isn't activated. It appears on Windows 10 and Windows 11 when the system can't find a valid licence — for example after a clean install, a hardware change, or an edition upgrade that left the old key behind. Beyond the on-screen text, an unactivated Windows also:

• Locks the Personalisation settings — you can't change wallpaper, accent colours, themes, or the lock screen.
• Shows occasional reminder notifications.
• Otherwise keeps working normally — updates and security still function.

So nothing is broken; Windows is just waiting for a licence. Importantly, you can't remove the watermark by editing a registry value or deleting a file for long — those "tricks" come back after the next update because the watermark is a symptom, not a setting. The real fix is to activate Windows.

The permanent fix: activate Windows

Activating removes the watermark instantly and unlocks every greyed-out setting. You have a few routes depending on your situation.

Option 1 — Use a licence you already own

If you have a product key or a digital licence tied to your Microsoft account, go to Settings → System → Activation, choose Change product key (or sign in), and enter it. This is the route to use whenever you have a valid key for the PC.

Option 2 — Activate with KMS (free)

If you don't have a key — common on a fresh install or an older machine — the free route is KMS activation, the same volume-activation technology Microsoft built for businesses. The simplest tool for it is KMSPico, which installs the correct Generic Volume Licence Key for your edition, runs a local Key Management Service host, and activates Windows in one click. The watermark vanishes and Personalisation unlocks immediately. Step-by-step guides are available for Windows 11 and Windows 10.

Option 3 — Activate manually from Command Prompt

Prefer to do it yourself? Open an elevated Command Prompt (right-click → Run as administrator) and use the built-in licensing tool:

> slmgr /ipk <your-edition-GVLK>   # install the generic key
> slmgr /skms 127.0.0.1            # point at a local KMS host
> slmgr /ato                       # activate
> slmgr /xpr                       # confirm it worked

The full key list and explanation of each command is in our slmgr commands reference.

Why the watermark comes back if you only "hide" it

You'll find old tutorials that delete a file in System32 or tweak a registry key to hide the text. These can clear it temporarily, but Windows rebuilds the activation state during updates, so the watermark returns — and you've changed nothing about the underlying licence. Activating is the only approach that removes it and unlocks Personalisation, and it survives updates because the licence lives in the activation store.

After activating: confirm it's gone

Once you've activated, the watermark should disappear within a few seconds (a reboot guarantees it). To double-check the licence itself, open Settings → System → Activation and look for "Windows is activated", or run slmgr /xpr — see how to check activation status for all three methods. If activation throws an error code instead, our activation-error index has a targeted fix for each one.

Quick summary

• The watermark = Windows isn't activated. It's harmless but locks Personalisation.
• Hiding it via registry/file tricks is temporary; activation is permanent.
• Use your own key if you have one, or activate free via KMSPico / the slmgr commands.
• Confirm with slmgr /xpr and you're done.
