If you'd like to know your current user account, of course you can query environment variables like this:
PS> $env:userdomain PS> $env:username
You get a lot more information including your security identifier (SID) by using the appropriate .NET methods:
PS> [System.Security.Principal.WindowsIdentity]::GetCurrent() PS> [System.Security.Principal.WindowsIdentity]::GetCurrent() | PS> [System.Security.Principal.WindowsIdentity]::GetCurrent() | PS> [System.Security.Principal.WindowsIdentity]::GetCurrent() |
