Win7 Activator for All 32 Bit and 64 Bit Win7 OS Activation Service
While Windows is typically set to activate automatically when you install it, you may find a time when you need to manually activate it. Activating Windows verifies that your copy of Windows is only being used by your computer hardware, which helps prevent piracy. If you’ve just upgraded your computer, or you weren’t able to get online after installing Windows, you’ll probably need to activate your copy manually.
With this activator, no need provide product key. Just unpack it to your desktop, then double click to run it. Your OS WIN7 will be activated after reboot
