Windows 8: Checking Activation Status

Are you a user of Windows 8 Professional or Enterprise edition and would like to check the status of activation on the local computer? Want to make sure that the computer is connected properly to the Key Management Server (KMS) or used your Multiple Activation Key (MAK) properly? Or are you a home user and just want to make sure your computer is fully activated?

Included in Windows 8 (this tool was first made available in Windows Vista, so this tip will work on earlier versions of Windows) is very useful utility that will help you check the status of activation of your computer:

• From the Start screen, type CMD and press the Enter key
• At the command prompt, type slmgr.vbs /dli and press the Enter key (for a more detailed report run slmgr.vbs /dlv).

After a few seconds you will be presented with a pop-up message with your activation status.

Note: Windows 8 supports a new command called: LICENSINGDIAG (e.g. licensingdiag.exe -report c:\output\license_report.xml -log c:\output\license.cab), that generates a report about the activation and registration data on the local computer.  This tool appears to be some type of technical support diagnostic tool based on the way it runs.
