Windows activation is part of the Microsoft “Windows Product Activation” process. 
The activation differs from the installation process in that it requires a product code.
It is also different from the post-installation registry.
Instead, the goal of Windows activation is to establish a link between a licensed copy of Windows and a specific computer system.
The creation of this link, in theory, should prevent the same copy of Windows from being installed on more than one machine;
As it was possible with earlier versions of the Windows/operating system.
After installation, Windows takes information from your video display adapter, SCSI and IDE drive adapters, processor type, and serial number; 

Both the serial number of the hard disk and the network adapter of the media control address access to form a unique identity for your equipment.

Two computers should not have the same hardware signature.
When you try to install the same copy of Operating System/Windows on more than one machine and then try to activate it over the Internet or by phone, the activation will fail.


Unlike Windows XP and Vista, not activating Windows 7 leaves you with an annoying but somewhat usable system.
And if you don’t activate earlier or don’t have a Product key, it will led you in search of How to Activate Windows 7 Using Cmd.
According to a post from the Microsoft developer blog in “Microsoft Developer Network,”
If you choose not to activate Windows 7 during installation, a message “Activate Windows Online Now” will appear in the system tray.
If you do not activate, then you will see an “Activate now” message every day from day four till day 27.
From day 27 till day 30, you will get the “Activate now” message option every four hours until the 30th day.
After 30 days, you will get the option “Activate now” every hour, along with a warning that your version of Windows is not original when you open the Control Panel.
Furthermore, Windows 7 does not perform any system updates after the grace period.
Finally, Windows will automatically activate with the black wallpaper image every hour, even after you change your preference again.
This behavior continues until you successfully activate the Windows 7.
Bill Gates complained about the copy of his company’s Altair Basic software by computer fans.
