Who created KMS Online?

You will be amazed to know that it was originally introduced by Microsoft engineers.

Why did they create it?

What was the benefit of this?

Let’s see.

In a huge computer lab which has 1000 computers.

All of them use the Windows operating system.

The owner of that lab has to purchase Windows licenses in bulk or a volume license.

It will be very difficult for him to activate every Windows one by one.

Here comes KMS.

He will use this activator tool to activate all the windows at once.

On a large number of computers, Windows crashes frequently.

So it should be reinstalled.

And after every reinstall, it needs to be activated again.

This activator is 100% free from any antivirus detection.

It activates Windows and Office for 180 Days.

It applies Instant Global Activation in Windows 8.1 and later versions.

It means that the edition of Windows will be changed after activation.

This tool automatically activates Windows over the internet.

You can use the ‘Create Renewal Task’ option for permanent activation.

But once every 6 months it needs to be connected to the internet.

Renewal Task creates a weekly scheduled task to renew KMS Servers.

It stores required files in the C\Windows\Online_KMS_Activation_Script directory.

The system will be deactivated if the date of the system is behind 6 months.

But it will be reactivated if the date is corrected.

The main advantage of this tool is that it is 100% clean from AV detection.

While KMSPico and other activator tools have AV detection issues.
