Its working principle is: to cheat Windows activation service by injecting a SLIC (System Licensed Internal Code) table into the system before Windows starts, which makes Windows falsely take the computer for a legitimate OEM PC. Windows Loader is well known for the capability of bypassing Microsoft’s WAT (Windows Activation Technologies) and is considered to be the safest Windows activation tool for Windows 7. Additionally, it also supported simulating specific computer brands to perform system activation. 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.
