I'm pulling a xls into a $var with import-excel. Storing a 2-digit column name in var $OSV

This Works: $var | Where-Object -Property $OSV -Match 'Windows'

This Doesn't: $var | Where-Object {$_.OSV -Match 'Windows' }

I've tried using single/double quotes, tried -like, verified the value I'm using shows up when I pipe $var| gm as the correct property name. I've tried little changes in the formatting of that section of the command and everything I do that doesn't generate an error takes the same time to run thru the array it just never outputs anything. The ideal end result will be something like:

$var| Where-Object {$_.OSV -Match -'Windows -and $_.OSV -Notmatch 'Server'}

Update: $var | Where-Object {$_.$OSV -Match 'Windows' } This Works.
