Uninstall Windows Product Key Before Selling PC - A Guide

Transferring Your Windows License to a New PC
Are you planning to sell an older computer while retaining the ability to utilize your existing Windows license on a new machine? A lesser-known command within Windows provides a method for accomplishing this.
Understanding License Transfer Regulations
It's important to acknowledge that the permissibility of transferring your Windows license is governed by a complex interplay of agreements between Microsoft and your Original Equipment Manufacturer (OEM).
Proceeding with the following instructions is done at your own discretion. Familiarize yourself with the relevant legal terms before attempting a license transfer.
Verifying Your Product Key
Prior to initiating the transfer process, ensure your product key remains linked to your current PC or original installation media.
If the key is not readily accessible, a quick online search will reveal methods for its recovery. Confirming key availability is a crucial preliminary step.
This ensures a smooth transition and avoids potential activation issues on your new computer.
Successfully completing these checks will prepare you to move your Windows license effectively.
Removing Your Windows Product Key
Initially, obtaining the activation ID is necessary. To accomplish this, launch a command prompt with administrative privileges and execute the following command:
slmgr /dlv
A message box from Windows will appear, displaying details regarding your PC’s license status. Carefully record your activation ID from this information.

The process of removing your product key requires the utilization of the /upk switch, in conjunction with your specific activation ID.
slmgr /upk 507660dd-3fc4-4df2-81f5b559467ad56b

Successful execution of this command will result in a confirmation message indicating that the product key has been successfully uninstalled.

Confirmation of uninstallation will be provided upon correct execution of the command.

Product Key Installation
The process of installing your product key on a new personal computer is straightforward. It requires only the activation of an administrative command prompt and the utilization of the /ipk switch.
Upon successful execution, and if the provided key is valid, a confirmation message will be displayed indicating that the key has been successfully installed.
This completes the installation procedure.
Detailed Steps
The installation is achieved through a simple command-line operation. Ensure you are running the command prompt with administrative privileges for the process to function correctly.
The system will verify the entered product key. A successful verification will result in a notification confirming the key’s installation.
No further action is typically required after receiving this confirmation.
The process is designed to be quick and efficient, allowing you to promptly activate your software.
