How to check if Windows and Office are activated

Three quick ways to check your activation status, and what to do if Windows or Office isn't activated.

Updated 7 October 2026

01Check Windows in Settings

  1. Windows 11: open Settings > System > Activation. Windows 10: open Settings > Update & Security > Activation.
  2. Look at the Activation state line.

Another sign: an unactivated PC shows an Activate Windows watermark in the bottom-right corner, and some personalization settings are locked.

02Check Windows with a command

Open Command Prompt and run:

slmgr /xpr

"The machine is permanently activated" means you're done. For details, run:

slmgr /dlv

The Description line shows your license channel: RETAIL, OEM or VOLUME_MAK/VOLUME_KMSCLIENT. A Volume license on a home PC usually means it was activated with a shared key or an activation tool, and it may stop working. See Retail vs OEM vs Volume keys.

03Check Office

  1. Open Word or Excel and go to File > Account.
  2. Under Product Information, you should see Product Activated and the edition name, for example Microsoft Office Professional Plus 2024.
  3. If you see Product Activation Required or a yellow bar asking you to activate, click Change Product Key and enter your key.
