Activate Windows 7 using an Internet connection
created by ares, 20. 02. 2012
You must activate Windows within 30 days of installation. Activation helps verify that Windows on your computer is genuine and hasn't been used on more computers than the Microsoft Software License Terms allow. In this way, activation helps prevent software counterfeiting.
To activate online, you'll need your Windows 7 product key. You can find your product key on the computer or inside the Windows package—or in a confirmation e‑mail if you purchased and downloaded Windows 7 online. Go to the Microsoft website to see examples of product key stickers.
If you can't find your product key, you might need to buy a new one.
