Windows 8 Activation using Desktop Control Panel

With the first public available Windows 8 releaseWindows Developer Preview I had the chance to see how easy is Windows 8 activation.

Although you might have some difficulty to find the right Control Panel screen to activate Windows 8, you might get surprised that Microsoft Windows 8 has already been activated by the new operating system Action Center.

What is Windows 8 Activation ?

Let's start with What is Windows Activation for a Windows 8 setup.

Please note you should activate Windows 8 within the given 30-days period after installation date using either online activation or using phone activation. Automatic online activation will activate Windows 8 copy after 3 days later the new operating system software is used.

First display the Windows 8 Start screen where the tile theme is active and click the pinned by default Control Panel tile on the screen.

If your Windows 8 installation has not been yet activated automatically, or your Windows 8 computer does not have internet connection you will see the Activate Windows screen on display when the new Control Panel is running.

how to activate Windows 8 automatically

Windows is unable to detect a network connection right now. Establish network to complete activation.
The easiest way to activate is to connect to the Internet. Once you're connected, activation will happen automatically.

In order to activate Windows 8 using phone just like previous Windows OS (Windows 7 or Windows Vista), click on Activate by phone button shown on above screenshot. You can check the Windows activation by phone details here.

If your Windows 8 activation is completed you can see details again using the Control Panel. But this time you should switch to Desktop Control Panel which is the control panel we are used to than the new Windows 8 Control Panel.

When the new tile theme Control Panel is displayed on Windows 8 screen, scroll down on the left side of the Control Panel screen till you see "More sttings" option.
Click on "More settings" to display the Windows Vista or Windows 7 style Control Panel, called as Desktop Control Panel in Windows 8.
