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.

If you see the error 0xC004F074, it means that your internet connection is unstable or the server is busy. Please make sure your device is online and try the command “ato” again until you succeed.

  1. Wow this has helped me a lot. in the whole world there is nothing for free. I tried many ways but only ms guides helped me for free.

  2. slmgr.vbs show error message every time error is: “Error 0x8004100E occurred in connecting to the local WMI provider. On a computer running Microsoft Windows non-core edition, run ‘slui.exe 0x2a 0x8004100E’ to display the error text.” and slui.exe display error: “Invalid namespace”

  3. I used the methoud 3 it was very simple and real. my windows has activated. THANK YOU…..

  4. I used the “Method 1: Manual” process and it worked flawlessly.
    Thank you so much!

    1. Did you catch the part where it says that this server “slmgr /skms s8.uk.to” may be out of date and to use ““slmgr /skms kms8.msguides.com” instead?

  7. i run the Bat file method to activate my win8 enterprise edition but on cmd prompt show windows is activated successfully, but when i open system properties they closed as eye blink lid, ? and there is nothing to show activate or not activate, why and let you tell me reason of that.

  8. Thank you. I was able to install 8.1 after a power outage killed Windows 10. I used the cmd prompt method. Everything seems fine except I can’t see any offline help files. Is that because of something about this install method? If so, you might provide some solution, if there is one.
