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

A lot of people say Windows 8 or 8.1 isn’t 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.

Step 5: Activate your Windows using the command “slmgr /ato”.

Check the activation status again.

Hi there! I would like to ask you if this is a permanent activation of Windows 8.1 since many activators use the kms and it only activates for 180 days.
If I use the command in cmd.exe: slmgr -xpr
What message appears to you?
“It is activated for 180 days” or “this has a permanent activation”
Thanks in advance

  All method here will show activated for 180 days.
  Activation will automatic renew back to 180 days every seventh days when you online.

  Have you tried using the command in cmd.exe slmgr – xpr to see how long Windows is activated? In this case I ask for windows 8.1. The same would happen with the windows 10.
  If you use the command in cmd.exe: slmgr -xpr
  What message appears to you?
  “It is activated for 180 days” or “this has a permanent activation”
  Thanks in advance

The 1click.cmd method is foolproof and now I can enjoy this OS after doing the Updates but Win7 was my favorite…too bad it’s been 10 years since getting that one started and I am still learning before turning 60 in 2022.

Thank you,
It works.
However, I am concerned about security & privacy as a lot of programs found on internet contain viruses. I see we just activated windows using your kms8 server, can you please tell is your program clean and what do server part kms8 actually do in background?
also if i want my own server like this setup kms8 can you do it?
Kind Regards.

  Activation through kms8 server. Update from Microsoft just like retail version.
  If you want to run your own server, you need to contact Microsoft, buy KMS host key from Microsoft.
