is KMS-Digital-Online_Activation_Suite safe valid and genuine to activate windows 10?

Posted on


I bought Windows 10 Pro Key online through Lazada, the seller gave me a product key but upon activation it failed to activate the system.

I asked the seller for some help and then he gave me a link to download some files and open it to automatically activate the system.

I read the ReadMe.text file and found this line This tool is the fork of mephistooo2 KMS-Digital-Online_Activation_Suite. I started to think if he is tricking me because as far as I know, using KMS to activate windows is illegal.

Anyway, I downloaded the file and run a security scan and the result is 0 threat found.


KMS is a standard Windows activation mechanism used for “volume” licenses. That is, instead of performing a permanent activation bound to the computer, it’s a license server that issues 120-day activations for all PCs on a corporate network.

So KMS itself is not illegal – but the illegal part that you’re describing comes from installing a fake KMS server to provide licenses that you don’t actually own. (I don’t know the specifics of MS licensing, but selling ‘real’ KMS activations off a real server to third parties is most likely not permitted either.)

The attached archive appears to do something very similar. The script mostly just runs some built-in Windows tools and configures a generic product key that tells Windows to use KMS, but it does not install a local fake KMS server nor does it configure any specific remote KMS server to be used (e.g. over the Internet).

However, the included slc.dll is unsigned, suspiciously short, and consists mostly of functions which do nothing. In other words, it has been patched to always generate a “successful KMS activation” ticket without ever contacting a KMS server at all. So I’m 99% sure that you were sent a crack.

Although this doesn’t imply that the license key you’ve bought is garbage, it’s very likely to be.

Key Management Service (KMS) is used to activate Microsoft products on clients using generic keys against a Volume Activation Service, hosted on a remote server. Legally owned volume licenses are installed on the server and activation is required typically every 180 days to keep the products activated on client machines.

Hacking tools using KMS activation emulate a fake KMS server on the local computer and trick Microsoft products to activate against it. Products activated this way have temporary valid license and when installing such hack tools, a task is often created to automatically renew it every 60 days.

In my opinion, Lazada has taken your money and gave you a hacking tool,
which by itself is dangerous to use as it might install unknown software
on your computer.
The product key you received is probably for KMS activation, so cannot be
used by itself for normal Windows activation.

I’m afraid your money is lost.
I recommend looking for a legitimate seller of Microsoft licenses.
