Look in Computer->System Properties. In the System Properties dialog, you should see a link: "Get More Features with a new Edition of Windows 7" in the Windows Edition section of the dialog. That link takes you to the Windows Anytime Upgrade page.

Also you can get the license key on-line from microsoft store or any microsoft retail store.Aloysius Jegan
