# systeminfo The Windows systeminfo command displays *a lot* of information! Use [[findstr]] to filter its output: ```powershell systeminfo | findstr /B /C:"OS Name" ` /C:"OS Version" ` /C:"System Type" ``` This can be used to semi-reliably determine if a machine is part of a domain. ```powershell systeminfo | findstr Domain ``` (Non-AD joined machines will almost always use WORKGROUP for the `Domain`, while AD-joined machines will often use a fully qualified DNS domain here.)
