***How to Remove Windows 11 home Product Key and Add Windows 11 Pro Product key with Command and Restore Back to Windows 11 Home Again

https://www.youtube.com/watch?v=BAulJJkJCrY&t=447s

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:

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

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

These articles explain how to uninstall your current Windows 11 product key and then install and activate a Windows 11 Pro product key using the command line:

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.

To swap your Windows 11 Home key for a Pro key via command line, first, open

Command Prompt as Admin, use slmgr /upk to remove the old key, then slmgr /cpky to clear the registry; next, use slmgr /ipk YOUR_PRO_KEY to install the new Pro key, and finally, restart your PC for activation to complete, potentially needing to run slmgr /dlv for status.
