> Now, Click on "Enter" to run the command
> The next thing to do is to set the KMS machine address;
  1. Use "slmgr /skms" or "slmgr /skms" to connect to my KMS server
  2. Finally, activate your windows by running the "slmgr /ato" in CMD
If you see the error 0x80070005, it means the server is busy. Please try the command “ato” again until you succeed.
Now recheck your activation status 😎

I'm happy to announce that I've found a way you can activate your Windows 8 or 8.1 without using the command prompt or a Kms client key.

This approach is the best if you ask me because you don't have to start trying multiple activation keys or hoping for the cmd prompt to work. It automatically activates your Windows permanently once you run the software on your PC.

Here's the best part, it also activates any Microsoft Office packages installed on your PC plus it is an offline activation process. However, for copyright reasons, I won't advise you to use this tool for commercial and long-term purposes.

The name of the tool/software is the KMSPico 8.1 activator tool. Without wasting much time, let's get started.

  1. Download the KSMPico Windows 8.1 activator tool
  2. Now, turn off real-time protection by opening Settings > Virus and Threat Protection > Manage Settings > Turn off real-time protection. You must do this, or else the antivirus will see the program as a threat and delete it.
  3. Next, go to your downloads, unzip the file, and run the program as an administrator.
  4. Once inside the app, Click on the "Activate" button and wait for some seconds.
  5. This should activate your Windows alongside other Microsoft packages. However, you can confirm this by typing the below prompt into your CMD.
  6. Open your CMD from the search icon  > run as administrator > and type this "slmgr /xpr" then ENTER.

That's all about activating your Windows 8/8.1 without activation code or software.

If the above tool doesn't work then you should reach out to us on WhatsApp since we've got an alternative app that should do the job.
