Laptop screen — checking Windows activation status

Seeing an “Activate Windows” watermark or wondering if a second-hand PC has a genuine Windows license? Here are three quick ways to check if Windows is activated and genuine — plus how to fix it if it isn’t.

🎯 Quick Answer:

Go to Settings → System → Activation. If it says “Windows is activated” (ideally “with a digital license”), you’re genuine. If not, a real Windows 11 Pro key from GenuineKeys365 fixes it in minutes.

1️⃣ Check via Settings (easiest)

  1. Press Windows + I to open Settings.
  2. Go to System → Activation (on Windows 10: Update & Security → Activation).
  3. Read the Activation state. “Windows is activated with a digital license” or “…with a digital license linked to your Microsoft account” means you’re genuine.

2️⃣ Check with Command Prompt (slmgr)

For a definitive answer, use the built-in licensing tool:

slmgr /xpr

Shows whether Windows is permanently activated or when the license expires.

slmgr /dli

Shows the license edition, part of the product key, and activation status.

Open Command Prompt (or Windows PowerShell), type the command and press Enter. A pop-up reports the status. “The machine is permanently activated” is what you want to see.

3️⃣ Look for the Watermark

An unactivated Windows shows a persistent “Activate Windows — Go to Settings to activate Windows” watermark in the bottom-right corner, and personalization options (wallpaper, accent colors) are greyed out. No watermark plus full personalization is a good sign your copy is activated.

🔎 Genuine vs Activated — the Difference

“Activated” means Windows accepted a valid key. “Genuine” means that key was legitimately issued and hasn’t been blocked. A copy activated with a cracked or abused key can later be flagged as not genuine. That’s why the source of your key matters — always use a real, legitimately-sourced license.

🛠️ Windows Not Activated? How to Fix It

  1. Go to Settings → System → Activation → Change product key.
  2. Enter your 25-character genuine key and click Next.
  3. Windows verifies the key with Microsoft and activates within seconds.

❓ Frequently Asked Questions

How do I know if my Windows 11 is genuine?

Open Settings → System → Activation. “Windows is activated with a digital license” confirms a genuine, verified license. You can also run slmgr /xpr for confirmation.

Why does my activated Windows now say “not genuine”?

This usually means the key was blocked (often a cracked, shared, or misused key), or a major hardware change de-linked the digital license. Entering a real, legitimately-sourced key resolves it.

Does the “Activate Windows” watermark harm my PC?

It doesn’t damage anything, but personalization is locked and you miss some updates. Activating with a genuine key removes the watermark and unlocks all features.
