How to Transfer Your Windows License to a New PC (2026 Guide)

Whether you’ve built a new PC, bought a new laptop, or replaced a dead machine, one question comes up fast: can you bring your existing Windows license with you, or do you have to buy a new one? The answer depends entirely on what type of license you have and getting it right can save you the cost of a new key, or save you hours of frustration trying to move a license that was never transferable in the first place.

This guide explains exactly which licenses can move, how to transfer them step by step, and what to do if yours can’t be transferred.

First: Find Out What Type of License You Have

This is the make-or-break question. There are two main consumer license types, and only one of them is transferable.

To check which type you have, open Command Prompt as administrator and run:

A small window pops up showing your license type. If it says RETAIL channel, you can transfer it. If it says OEM channel, you can’t. (You can also run slmgr /dlv for more detail.)

How a Digital License vs a Product Key Affects Transfer

There’s a second layer to understand: how your license is stored.

• Product key: A 25-character code. If you have the key written down and it’s a Retail key, you can type it into a new PC to transfer the license.
• Digital license: Newer activations are stored as a “digital license” linked to your hardware and, optionally, your Microsoft account. If a Retail digital license is linked to your Microsoft account, you can transfer it by signing in to that account on the new PC and using the Activation Troubleshooter.

The best-case scenario for transferring is a Retail digital license linked to a Microsoft account, that combination makes the move almost automatic.

How to Transfer a Retail License: Step-by-Step

Step 1 – Deactivate the License on the Old PC

A Retail license can only be active on one PC at a time. Before moving it, remove it from the old machine to avoid activation conflicts.

1. On the old PC, open Command Prompt as administrator.
2. Run: slmgr /upk (this uninstalls the product key).
3. Then run: slmgr /cpky (this clears the key from the registry for safety).
4. The old PC is now deactivated. It will show the “Activate Windows” watermark, which is expected — you’re moving the license away from it.

Step 2 – Note Your Product Key (or Confirm Account Link)

If you have a physical/email Retail key, have it ready. If your license is a digital license linked to your Microsoft account, make sure you remember which account it’s tied to — you’ll sign in with it on the new PC.

Step 3 – Install Windows on the New PC

Install Windows 11 on the new machine if it isn’t already (our USB clean install guide walks through this). During or after installation, you’ll activate with your transferred license.

Step 4 – Activate on the New PC

If you have a product key:

1. Go to Settings → System → Activation.
2. Click Change product key.
3. Enter your 25-character Retail key.
4. Click Activate. Done.

If you have a digital license linked to a Microsoft account:

1. Sign in to the new PC with the same Microsoft account.
2. Go to Settings → System → Activation.
3. Click Troubleshoot (appears if Windows isn’t activated).
4. Select I changed hardware on this device recently.
5. Choose your old PC from the device list, then click Activate.

What If Your License Is OEM (Can’t Be Transferred)?

If your check showed an OEM license, the license stays with the old PC, there’s no workaround that’s legitimate or reliable. Your options are:

• Buy a new Retail license for the new PC. This is the clean solution, and a Retail key has the bonus that it can be transferred to future PCs (unlike OEM). A Windows 11 Pro Retail key is $15 at Software Kings.
• Check if the new PC came with its own license. If your new PC is also a pre-built machine, it likely came with its own OEM Windows license already, in which case you don’t need to transfer anything.

Transferring a License After a Hardware Upgrade (Same PC)

A related scenario: you didn’t buy a new PC, but you replaced major components (especially the motherboard) and Windows deactivated itself. The fix depends on your license type.

Retail license: Use the Activation Troubleshooter (Settings → System → Activation → Troubleshoot → I changed hardware recently) and sign in with your Microsoft account. Retail licenses are designed to survive hardware changes.

OEM license: A motherboard replacement typically kills an OEM license permanently, because OEM keys are bound to the original motherboard. You’ll usually need a new license. This is one of the biggest practical reasons to choose Retail over OEM if you build or upgrade your own PCs.

Common Transfer Problems and Fixes

If you’re stuck, Microsoft also offers phone activation: run slui 4 from the Run dialog to get the phone activation flow, which is useful for license transfers that the automatic system flags.

Does Transferring Windows Also Transfer My Office License?

No — Windows and Office are completely separate licenses. Transferring Windows to a new PC doesn’t move Office, and vice versa. Office Retail licenses can also be transferred to a new PC following a similar process: deactivate on the old machine, reinstall and reactivate on the new one.

If your Office license is also OEM (pre-installed), it can’t be transferred either. A fresh Office 2024 Pro Plus license or the Windows 11 Pro + Office 2024 bundle covers both at once if you’re setting up a new PC from scratch.

Frequently Asked Questions

Can I transfer my Windows 11 license to a new PC?

Only if it’s a Retail license. Retail licenses can be deactivated on the old PC and activated on a new one. OEM licenses (which come pre-installed on store-bought PCs) are locked to the original motherboard and can’t be transferred.

How do I know if my Windows license is Retail or OEM?

Open Command Prompt as admin and run slmgr /dli. A window shows your license channel, “RETAIL” means transferable, “OEM” means not. You can also run slmgr /dlv for more detail.

Can I transfer an OEM Windows license to a new computer?

No. OEM licenses are permanently tied to the first PC’s motherboard. There’s no legitimate way to move them. You’ll need a new license — ideally a Retail key, which can be moved to future PCs.

Do I need to deactivate Windows on my old PC before transferring?

Yes, for a clean transfer. Run slmgr /upk and slmgr /cpky on the old PC to remove the key. This prevents “key already in use” errors on the new PC.

Will my digital license transfer automatically?

If it’s a Retail digital license linked to your Microsoft account, you can transfer it using the Activation Troubleshooter on the new PC after signing in with the same account. OEM digital licenses don’t transfer.

What happens to the old PC after I transfer the license?

It becomes unactivated and shows the “Activate Windows” watermark. If you’re keeping or selling it, you’ll need a separate license for it. If you’re recycling it, that doesn’t matter.

Can I transfer my license to multiple new PCs?

No. A Retail license activates one PC at a time. You can move it from PC to PC sequentially, but it can never be active on two machines simultaneously.

My motherboard died – can I move my license to a new motherboard?

If it’s a Retail license, yes, use the Activation Troubleshooter and sign in with your Microsoft account. If it’s OEM, a motherboard change usually voids the license permanently, and you’ll need a new one.

Does transferring Windows transfer my files and apps too?

No. Transferring a license only moves the activation rights. Your files and apps don’t move with the license, you’ll need to back them up and reinstall separately, or use a migration tool.

Is it cheaper to transfer a license or buy a new one?

Transferring a Retail license is free (you already own it). But if you have an OEM license that can’t transfer, buying a new Retail key at $15 is the only option, and it’s inexpensive enough that it’s not worth the hassle of trying to work around OEM restrictions.

Final Recommendation

Transferring a Windows license comes down to one question: Retail or OEM. If you have a Retail license, the transfer is straightforward, deactivate on the old PC, activate on the new one, done. If you have an OEM license, it stays with the original machine, and you’ll need a fresh license for the new PC.

The lesson for the future: if you upgrade or replace PCs regularly, always buy Retail. It’s the difference between moving your license for free every time versus buying a new one. At Software Kings, every Windows 11 key is a Retail license for exactly this reason $15, transferable, with activation support included.
