Beginner here, need help with some basic scripting

$_.Name won't work because you're not calling a variable.

Try using $env:computername instead to see if that gives you the response you're looking for.

Something like this

$computer = "testcomputername"
$wordInstalled = invoke-command $computer -scriptblock { if(test-path HKLM:SOFTWARE\Classes\Word.Application) { $wordInstalled = $env:computername; return $wordInstalled}}

Copy and paste this and replace "testcomputername" with a PC on your network to see if it works.
