Windows 10: How many Windows Servers can be activativated with one MAK key?

Not so far ago my company buy 4 Open Licenses for 4 new instances of Windows Server 2019 Standard 16 core.

In private cabinet I see only one new license with 1 MAK key for Windows Server 2019 Standard which has 45 activations.

My question is - I can use this key only for activation of this 4 new servers, or I can use it for activation of much more new servers at the same time, up to 45 in total without license violation?

Mak Key Enterprise question

Just for clarification, MAK keys are Multi Activation Keys, and are "not" VL keys. They don't activate via KMS. They are a special key used in leu of a KMS Key for testing purposes.

For example, normally Enterprise cannot be activated with a Retail Key, its VL only. As part of my Visual Studio Enterprise subscription, I get MAK keys for Enterprise to let me install and activate it for testing without having to setup a KMS server.

Its also a one time activation, like a Retail key. VL keys have to recheck / reactivate at set intervals with the KMS server. They will time out and fail activation if they can't connect to that specific KMS server to reactivate.

There is a limit on how many times a MAK can be used. That info is a bit fuzzy as Microsoft doesn't really say what that limit is? In any case my subscription is a NFR, Not For Resale. Those keys should never reach consumers or be resold in any way. They are part of your subscription.
