Help me in HTB-academy

I can’t seem to solve the first model in WINDOWS FUNDAMENTALS - Introduction to Windows.

What is the Build Number of the target workstation?
Which Windows NT version is installed on the workstation? (i.e. Windows X - case sensitive)

I tried the commands suggested by the materials provided.

xfreerdp /v:<targetIp> /u:htb-student /p:Password

and

Get-WmiObject -Class win32_OperatingSystem | select Version,BuildNumber

None of them is working! I am using the in-built instance by HTB.
