Can You Transfer a Windows 11 Pro Key to a New PC?

Yes — you can transfer a Windows 11 Pro key to a new PC, but only if you have a Retail license. OEM keys are permanently tied to the original hardware and cannot be moved. Knowing which type you have takes about 30 seconds to check.

💡 Quick answer: Retail keys are transferable. Deactivate on the old PC, then activate on the new one. OEM keys are not transferable — they’re bound to the original machine’s motherboard. If you need a transferable license, see our Windows 11 Pro Key Retail.

Step 1 — Check your current license type

Before anything else, confirm you have a Retail license. Open an elevated Command Prompt (right-click → Run as administrator) and run:

slmgr /dli

A dialog box appears. Look at the License Type line:

  • Retail — transferable, proceed with the steps below
  • OEM — not transferable; you need to purchase a new key for the new PC
  • Volume — a MAK or KMS key; not transferable in the standard sense

Step 2 — Check if your license is linked to a Microsoft account

If you linked your Windows 11 key to a Microsoft account, the transfer process is simpler — Windows can reactivate automatically on the new hardware if you sign in with the same account.

Check: Settings → System → Activation. If you see “Windows is activated with a digital license linked to your Microsoft account,” you’re set for the easy transfer path.

How to transfer a Retail key — two methods

Method A: Digital license linked to Microsoft account (easiest)

  1. Set up the new PC and sign in with the same Microsoft account used on the old PC
  2. Go to Settings → System → Activation → Troubleshoot
  3. Select “I changed hardware on this device recently”
  4. Sign in with your Microsoft account and select the new device from the list
  5. Windows reactivates — no product key entry required
✅ Link your key now: If you have a Retail key that’s not yet linked to a Microsoft account, go to Settings → System → Activation → Add a Microsoft account. This makes future transfers much easier.

Method B: Enter the product key manually

  1. On the old PC: open Settings → System → Activation → Change product key. Remove the key (or simply note it — it’s the 25-character code from your purchase email)
  2. Install Windows 11 on the new PC — skip the key entry step during setup
  3. Once Windows is running on the new PC: Settings → System → Activation → Change product key
  4. Enter your 25-character Retail key and click Next → Activate
⚠️ Deactivate first: Microsoft’s activation servers track how many machines a Retail key is simultaneously active on. If you activate on the new PC without deactivating the old one, you may hit an activation error. Deactivating on the old machine first avoids this.

How to deactivate Windows 11 on the old PC

There is no built-in “deactivate” button in Settings. The reliable method is via Command Prompt:

slmgr /upk
slmgr /cpky
  • slmgr /upk — uninstalls the product key from the current machine
  • slmgr /cpky — clears the key from the registry so it’s not stored locally

After running these, Windows on the old PC goes to an unactivated state. The key is now free to activate on the new machine.

What if activation fails on the new PC?

If you see an activation error after entering the key on the new machine, try phone activation — it bypasses the online server check and works for legitimate transfers:

  1. Open an elevated Command Prompt and run: slmgr /dti — this generates an Installation ID
  2. Call Microsoft’s automated activation line for your region (US: 1-888-352-7140)
  3. Enter the Installation ID when prompted — receive a Confirmation ID in return
  4. Run: slmgr /atp [Confirmation ID]

If an agent answers, explain you’re transferring a legitimate Retail license from an old machine to a new one. Microsoft handles this routinely.

Can you transfer a MAK key to a new PC?

No. MAK (Multiple Activation Key) activations are consumed permanently — once a machine uses one activation count, that count is spent even if you stop using the machine. MAK keys are designed for stable business fleets, not machines that rotate. See our MAK key guide for a full explanation of how activation counts work.

Frequently asked questions

Do I need to uninstall Windows from the old PC before transferring?

No. You just need to deactivate the key using slmgr /upk and slmgr /cpky. The old PC will still have Windows installed — it just won’t be activated. You can leave it, reinstall, or wipe it as needed.

Can I transfer to a PC with a different Windows edition?

No. A Windows 11 Pro Retail key only activates Windows 11 Pro. You cannot use it to activate Windows 11 Home on the new PC. The edition must match.

Does replacing the CPU count as a new PC for activation purposes?

Generally no. Microsoft’s hardware fingerprint is primarily based on the motherboard. CPU, RAM, and storage changes typically don’t trigger a reactivation requirement. Replacing the motherboard does.

I lost my product key. Can I still find it?

Yes — check your original purchase email from MyLegitKeys. Alternatively, on the old PC while it’s still activated, tools like ShowKeyPlus (free, from Microsoft Store) can retrieve the installed key. slmgr /dlv will also show partial key information.

What if the new PC already has a different Windows version installed?

You can enter your Retail key over any existing activation. Go to Settings → System → Activation → Change product key and enter your key. If the existing install is the wrong edition, you may need to run the installer fresh. See our guide on activating Windows 11 after a clean install.
