Windows 10 began to introduce a new way of legal authorization - digital license activation. Its most obvious feature is that it does not need the traditional product keys or activation codes. Instead, it uniquely identifies a user by recording and comparing the hardware information (HWID) of the user's current computer, thereby is able to automatically reactivate Windows 10 after reinstalling system in the future. The advantage is obvious: the user does not have to remember his Windows product key or activation code any more; and as long as your hardware is unchanged, you can always quickly, automatically and permanently reactivate your Windows 10 with ease.

Windows Loader (AKA: Windows 7 Loader By Daz, Windows 7 Activator) is a very popular and perfect (due to its pretty high success rate, good stability and strong ability to correct mistakes) universal activator for full series of and all editions of Windows Vista/7/2008 (R2)/2012 (R2) (including both 32-bit and 64-bit and all languages), developed and maintained by Daz from My Digital Life forum. Additionally, it also supported simulating specific computer brands to perform system activation.

Digital license is a simpler and more efficient way of activation/authorization newly adopted by Windows 10, which only relies on the configuration information of your computer hardware. After activating system for the first time, as long as you don't change the CPU and other devices connected to the mainboard, you can feel free to connect to Microsoft server to repeatedly, automatically and permanently activate your Windows 10 at any moment, without having to input the product key again and again every time you install the system.
