ANSWER 1

Score 117

([Security.Principal.WindowsPrincipal] `
  [Security.Principal.WindowsIdentity]::GetCurrent() `
).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)

This retrieves the current Windows identity and returns $true if the current identity has the Administrator role (i.e., is running elevated).

ACCEPTED ANSWER

Score 70

[bool](([System.Security.Principal.WindowsIdentity]::GetCurrent()).groups -match "S-1-5-32-544")

Breaking apart what this does:

[bool] - Cast the end result to a bool.
[System.Security.Principal.WindowsIdentity]::GetCurrent() - Retrieves the WindowsIdentity for the currently running user.
(...).groups - Access the groups property of the identity to find out what user groups the identity is a member of.
-match "S-1-5-32-544" checks to see if groups contains the Well Known SID of the Administrators group, the identity will only contain it if "run as administrator" was used.

ANSWER 3

Score 66

In Powershell 4.0 you can use requires at the top of your script:

#Requires -RunAsAdministrator

Outputs:

The script 'MyScript.ps1' cannot be run because it contains a "#requires" statement for running as Administrator. The current Windows PowerShell session is not running as Administrator. Start Windows PowerShell by using the Run as Administrator option, and then try running the script again.

Your code :

invoke-command -computername cavl-ghwwsc3 -command { ([Security.Principal.WindowsPrincipal] 
  [Security.Principal.WindowsIdentity]::GetCurrent()
).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)}

is working fine but how to launch it remotely in current user session (not in powershell elevate admin rights because it return my admin isadmin value to remote computer, not current log user if this user isadmin.
