How could I transfer my retail digital license windows 10 pro to a new pc and upgrade to windows 11 pro?

Step 1: Confirm your license type

First, check that your Windows 10 Pro license is transferable (Retail, not OEM). On your old PC, open PowerShell or Command Prompt and run:

slmgr /dli

Look for the Description line:

• If it says Retail, it's transferable.
• If it says OEM, it's tied to the original hardware and cannot be transferred.

Step 2: Unlink or deactivate the license on the old PC

If your license is Retail:

1. Sign out of your Microsoft account (optional, but helps).
2. Deactivate the license:

      slmgr /upk
      slmgr /cpky
   

   • /upk uninstalls the product key.
   • /cpky clears it from the registry (prevents accidental reuse).

This effectively frees the key for activation elsewhere.

Step 3: Find your product key (if you don't already have it)

Still on the old PC, run:

wmic path softwarelicensingservice get OA3xOriginalProductKey

or, if that doesn't return a key:

slmgr /xpr

If you bought Windows 10 Pro digitally via Microsoft Store, the key might be linked to your Microsoft Account instead — check underhttps://account.microsoft.com/devices

Step 4: On the new PC (Windows 11 Home)

Option 1 — If you have a product key

1. Go to Settings → System → Activation → Change product key
2. Enter your Windows 10 Pro key
3. Windows 11 will automatically upgrade from Home → Pro, then activate online.

Option 2 — If your license is linked to your Microsoft Account

If your Pro license was linked to your Microsoft account (digital entitlement):

1. Sign in to Windows 11 Home with the same Microsoft account used on the old PC.
2. Go to Settings → System → Activation → Troubleshoot
3. Choose I changed hardware on this device recently.
4. Select your old PC from the list → This is the device I'm using right now.
5. Windows will reassign the Pro license and automatically upgrade and activate.

Step 5: If Automatic Upgrade Fails

If the product key doesn't immediately upgrade:

1. Open Command Prompt (Admin) and run:

      changepk.exe /productkey XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
   

2. Reboot → the upgrade process should start.
