To remove a Windows 11 Home product key and add a Pro key using the command line, follow these steps in

Command Prompt (Admin):

1. Remove Current Product Key 

Use these commands to uninstall the current key and clear it from the registry: 

• slmgr /upk — Uninstalls the currently installed product key.
• slmgr /cpky — Removes the product key from the Windows registry to ensure it is completely cleared. 

• 
  

2. Add New Windows 11 Pro Key 

You can install your new Pro key directly using the following command:

• slmgr /ipk <Your-Pro-Product-Key> — Installs the new 25-character product key.
  • Example: slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX 

• • 
    

3. Trigger Activation

After installing the key, force Windows to communicate with Microsoft's servers to activate: 

• slmgr /ato — Attempts to activate the installed product key online. 

• 
  

Troubleshooting: Upgrade via Generic Key 

If the Pro key is rejected because the OS is still in "Home" mode, you may need to force the edition upgrade first using a generic Microsoft upgrade key: 

1. Run changepk.exe /productkey VK7JG-NPHTM-C97JM-9MPGT-3V66T.
2. Wait for the system to process the upgrade and restart.
3. Once restarted, use the slmgr /ipk command from Step 2 to enter your purchased Pro key for final activation. 

3. 
   

Note: Always ensure your device has an active internet connection before running the activation (/ato) command.

Thinking

Searching

Yes, you can typically recover or restore your Windows license after running

slmgr /upk (uninstall product key), as the command only removes the key from the active operating system. 

Recovery depends on your original license type: 

1. OEM (Pre-installed) Licenses 

If your computer came with Windows from the factory (Dell, HP, etc.), the key is embedded in the motherboard's BIOS/UEFI firmware. The /upk command does not erase this hardware-level key. 

• How to recover: Open Command Prompt as Administrator and run:
  wmic path softwarelicensingservice get OA3xOriginalProductKey.
• To Reactivate: Restarting the computer or clicking "Troubleshoot" in Settings > System > Activation often triggers Windows to find this hardware key and reactivate automatically. 

• 
  

2. Digital Licenses (Linked to Microsoft Account) 

For Windows 10 or 11, if your license is linked to your Microsoft Account, it is stored on Microsoft's servers rather than just as a local key. 

• How to recover: You do not need the physical 25-character key. Sign in to your Microsoft Account on the PC, then go to Settings > System > Activation and use the Activation Troubleshooter. 

• 
  

3. Retail Licenses (Bought separately)

If you bought a retail box or a digital key from a store, slmgr /upk removes it from the software environment. 

• Digital Purchase: Check your Microsoft Account Order History or the confirmation email from your purchase to find the 25-character key.
• Third-Party Tools: Before restarting or reinstalling, tools like ShowKeyPlus (available on the Microsoft Store) or NirSoft ProduKey may still be able to retrieve key fragments from the registry or firmware. 

• 
  

Summary of Important Commands

• slmgr /dlv: Check your current license status and identify the "Licensing channel" (OEM, Retail, or Volume).
• slmgr /ipk <Your-Key>: If you found your key, use this command to reinstall it manually.
• slmgr /ato: Use this to force Windows to attempt online activation after reinstalling a key.

To remove your Windows 11 Home license using the command prompt, run Command Prompt as an administrator and use

slmgr /upk to uninstall the key, then slmgr /cpky to clear it from the registry, effectively putting Windows in an unlicensed state, which is useful for transferring retail licenses or troubleshooting activation.
