How to get a list of Windows 2008R2 remote desktop users?

Question

Windows Server

Greetings!
There is a server with Windows Server 2008R2 Enterprise. It has more than 200 users, most of which are already inactive and blocked, but it is forbidden to delete them.
Task: get a list of "live" users.
I was able to google a lot of PowerShell solutions, but the following problem came up - most of them do not work, since I have PowerShell v.2.0 (for some reason, the update will not be released in the next 2-3 days).
I found the command Get-WmiObject Win32_UserAccount, which works on my version, but it displays the entire list. It has a -filter parameter, which, as I suspect, can potentially filter out the users I need, but alas, I can’t figure out how to set it ...
Thanks in advance to all who answered!
