A Windows activation key is a unique 25-character code that is used to activate and verify the authenticity of a copy of Microsoft Windows operating system. When you purchase a new computer or install a fresh copy of Windows on your PC, you will need to enter an activation key to activate your operating system.
Without a valid activation key, you will be limited to a trial version of Windows, which will expire after a certain period of time, typically 30 days. During the trial period, you may also encounter restrictions such as being unable to personalize your desktop or access certain features of the operating system.
To activate your copy of Windows, you will need to enter your activation key during the installation process or after the installation is complete. The activation key can usually be found on a sticker on the computer itself or in the documentation that came with your PC.
It is important to note that using a pirated or counterfeit activation key is illegal and can lead to serious consequences, including fines and legal action. Therefore, it is always recommended to obtain a legitimate activation key from a reputable source.
In summary, a Windows activation key is a crucial component in activating your copy of Microsoft Windows operating system, and it is important to obtain a legitimate activation key from a reputable source to avoid any legal consequences.
