Regarding "Number of Registered Users:"　in SEPM console.

Greetings,

This section seems to count the number of total check in user by using computer account name.
In a word, it can't count check in user total number accurately. 

For instance, login to the computer A using “administrator” user account and then check in to the SEPM, and it count 1 on "Number of Registered Users:".

But, login to the another computer B using “administrator” user account and check in, It count 1 not 2.
Of course, it can get same result using another user account name and it’s not matter whether you are in the domain or in the workgroup. 

A and B have “administrator” user account name but it is not same user account. So I think it should count as another user on "Number of Registered Users:".

If there is no reason for this specification, I think this section should implement for more user friendly.
I don’t understand why SEPM has such a specification.

Thanks!
