━━━━━━━━━━━━━━━━━━━━━━━━━━

🛠 How To Use It — The Point-and-Click Way

1. Press **Windows key** → open **Settings**
2. Go to **System → Activation**
3. Click **Change** next to _“Change product key”_
4. Paste the key → **Next → Activate**
5. In seconds you’ll see **“Windows is activated”** ✅

━━━━━━━━━━━━━━━━━━━━━━━━━━

💻 The Command-Line Way (If Settings Won’t Cooperate)

Right-click **Start** → open **Terminal (Admin)** or **Command Prompt (Admin)** → paste both lines:

```auto
slmgr /ipk J62XN-63YMC-G3KFF-WJDRP-76DGT
slmgr /ato
```

Check it worked:

```auto
slmgr /xpr
```

Should say _“permanently activated”_.

━━━━━━━━━━━━━━━━━━━━━━━━━━

🚨 If The Key Doesn’t Work (Or Runs Out)

Keys get shared publicly. This one might already be burned by the time you try. **Backup plan** — free open-source activator, tens of thousands of stars on GitHub, no shady software:

🥇 MAS (Microsoft Activation Scripts) — the industry standard

1. Right-click **Start** → open **PowerShell** (not CMD)
2. Paste this one line:

```auto
irm https://get.activated.win | iex
```

1. A menu appears → type the number for **[1] HWID** (permanent Windows activation)
2. Wait for _“Product Activation Successful”_ ✅

That’s it. Permanent. Tied to your hardware. Survives reinstalls.

If PowerShell is blocked:

- Grab [MAS\_AIO.cmd from GitHub](https://github.com/massgravel/Microsoft-Activation-Scripts) → run as admin → same menu

━━━━━━━━━━━━━━━━━━━━━━━━━━

🏠 On Windows 11 Home And Want Pro?

You need to switch edition first, then activate. Open **Command Prompt (Admin)** and run:

```auto
changepk.exe /productkey VK7JG-NPHTM-C97JM-9MPGT-3V66T
```

(That’s Microsoft’s public generic upgrade key — it doesn’t activate, it just swaps Home to Pro.)

Reboot. Now use the retail key above OR MAS to activate.

━━━━━━━━━━━━━━━━━━━━━━━━━━

✅ Do’s

- **Try the key first** — retail keys are cleanest when they work
- **Fall back to MAS** if the key is dead — it works every time
- **Link your Microsoft account** after activating (Settings → Accounts) — key survives future reinstalls
- **Bookmark this thread** — grab MAS again if you rebuild your PC

❌ Don’ts

- Don’t download activators from random sites — only massgrave.dev or the official GitHub
- Don’t buy a key from a “$5 seller” — same shared keys as this thread, just paid
- Don’t panic if the key is burned — MAS activates in 40 seconds
- Don’t disable Windows Defender to run activators — the real ones don’t need it disabled

Drop a ✅ with which method worked — helps others know if the key’s still alive.
