Changing or viewing remote computer’s description, name and other options related to Win32_WmiObject and class Win32_OperatingSystem is relatively easy with powershell. Just type in new script in PoweShell ISE or in notepad and save it as .ps1 file.

$OSValues = Get-WmiObject -Class Win32_OperatingSystem -ComputerName "remote_computer_name"
$OSValues.Description = "remote_computer_description"

You can as well display current description and other options by typing:

Get-WmiObject -Class Win32_OperatingSystem -ComputerName "remote_computer_name" | Select description
