new KMS and WIN10

How many clients have already contacted KMS server? You need to have at least 25 workstations or 5 servers for KMS host to start activating endpoints.

ok, where can I check this ?

I also have installed VAMT.

You need to issue slmgr /dlv command on KMS host and look for current count figure.

Hello,

here is the screenshot.

So your current count is 8 endpoints. You still need some more for KMS  server to start activating.

ok, I see.
But I have installed several KMS licenses.
I have installed WIN2016 and WIN10 licenses.

I want to check all installed licenses with this CMD -> slmgr /dli all
A window pops up but I cannot scroll down.
How to see all licenses here ?

According to this MS thread it is possible to copy&paste content of slmgr /dli all command using ctrl+c and ctrl+v

Thanks , that helps a lot.

From the command slmgr /dlv all , I cannot find my WIN10 KMS key...
what happens here because I have installed the key.

I can see all my Server KMS keys but not my WIN10 key.

I tried again to enter my WIN10 Enterprise KMS key to VA Services.

But this failed always. Can you help me out please ?

My KMS Server is WIN2016.
I think I cannot install here WIN10 KMS key right ?

You don't need to. The KMShost for WS2016 should activate KMSclient for Win10 without issue.
As I pointed earlier for now your current count for KMS clients is not enough for KMS host to start activating clients. You need at least 25 clients contacting host. Also pls ensure that all your clients have correct KMS key as per this MS article:

ok,
in the past I have issued MAK keys.
Is it possible to change from MAK to KMS ?
I have seen in VAMT tool I can install a new key, can I do it with this VAMT ?

is it possible to increase the current count ? Do you have some recommendations ?

ok I solved it with VAMT tool.
I choosed 25 old WIN7 machines and installed the new kms host key on it.
The second staep was the activation.
Now the count is 25 and my system are all activated and licensed.

Big thanks to all here. :-)

Hi,

glad I was able to help. Regarding your last comment - I hope you installed on those old WIN7 machines new KMS client not KMS host key.
