Mastering Slmgr: Your Guide to Effective Windows License Management
The Software Licensing Management Tool (Slmgr) is an integral part of Windows, enabling users to manage their licenses with efficiency. This guide will take you through the process of using Slmgr to install, uninstall, activate, view, or extend your Windows license.
Detailed Instructions for Using Slmgr
Step 1: View Your Windows License Information
To see your license details, launch the Command Prompt in elevated mode. Execute the following command:
slmgr /dli
This will provide a brief overview of your license, including the Partial Product Key. For in-depth information, use:
slmgr.vbs /dlv
Running:
slmgr /xpr
will indicate whether your license is active or will expire soon.
Pro Tip: Make sure to run Command Prompt as an administrator for proper access.
Step 2: Activate or Deactivate Your Windows License
To activate your Windows, you have the option of either online or offline methods:
For online activation, run:
slmgr /ato
For offline activation, use:
slmgr /dti
If you wish to activate using an Activation ID, execute:
slmgr /atp <Activation-ID>
To deactivate Windows, the command is:
slmgr /upk
Pro Tip: Keep your Activation ID accessible for offline activations.
Step 3: Install and Uninstall Your Windows Product Key
If installing a new product key, you must first uninstall the current one:
slmgr /upk
Next, to remove the corresponding registry entry, run:
slmgr /cpky
Now, you can install the new Product key with:
slmgr.vbs /ipk <Product-Key>
Step 4: Extend Your Windows License
To extend the rearm of your Windows license, execute these commands in sequence:
slmgr -rearm slmgr -dlv slmgr -ato
Pro Tip: Extending licenses generally applies when not using a product key, as Windows 10/11 can function without one.
Step 5: Activate Windows Using Slmgr
To activate your system with your valid Product key, execute:
slmgr.vbs /ipk <Product-Key>
Ensure you have your Product key available beforehand.
Step 6: Remove Your Windows License with Slmgr
To uninstall your current product key and deactivate your license, simply use:
slmgr /upk
Don’t forget to delete the associated registry entry afterwards:
slmgr /cpky
Extra Tips for Slmgr
