Best practice for installing Office 365E3

@Nuno Silva forgot to answer your question:

Yes even if it is not a shared computer.

Here's what is the Thread stating:

In Microsoft 365 Apps version 1910 and later, we made the following improvements:

• Users can install Microsoft 365 Apps on a new device without being prompted to deactivate it on another device. If a user has more than 10 devices with Microsoft 365 Apps activated, then the device that hasn't been used for the longest amount of time is automatically deactivated.

• When Microsoft 365 Apps on a device has been deactivated, either from the portal or because a license has been removed, a new user on that device can activate Microsoft 365 Apps without an error.

• When a user activates Microsoft 365 Apps on a device and a second user signs on to that device, both activations are now displayed in the activation report in the Microsoft 365 admin center.

So if I am correct, I can use my account to install the app. After that anyone with the licence can log in with his own AD account and activate his licence.

Finally, It seems that the sysprep cleans up my licence because in does not appears in my activated licences. 

Am I doing OK like that?

Cheers
