One Windows Command Every IT Admin Should Know

/0 Comments/in /by

Here’s a genuinely useful (and somewhat underappreciated) Windows command:

whoami /all

What it does:
Shows everything about the currently logged-in user — including:

  • User SID
  • Group memberships
  • Privileges (like admin rights, UAC elevation, etc.)
  • Logon type

Command:

whoami /all

Why it’s nice to know:

  • Great for troubleshooting permission issues
  • Quickly confirms if a user actually has admin rights
  • Helps with domain/debugging scenarios (especially in enterprise environments)
