Newest methods to activate Windows 8/8.1 for FREE without additional software

A lot of people say Windows 8 (or 8.1) is not a patch on Windows 7 but I don’t think so. Perhaps its Metro user interface is more difficult to use than traditional Start menu and you will have to spend hours to get the run of things. However, there is no denying the fact that Windows 8 shows outstanding performance against earlier Windows versions. Reduction of startup time is the easiest to see. Besides, if you own touchscreen computer, an upgrade to Windows 8/8.1 or Windows 10 is needed in order to make maximum use of your hardware.

In today’s post, I will show you two ways to activate Windows 8 or 8.1 for FREE without using any software. If you really want to know how it works, please try first way (manual method). Or you can follow second way (batch file) if you need save your time. The following are the detailed instructions for activating all versions of Windows 8.1 and 8.
