If there is one question I could say I get the most in PowerShell, it is:
How do I check my version?
Its not a hard thing, but its not an obvious thing. We can actually check our version with a build in variable called PSVersionTable
$psversiontable.PSVersion
Major Minor Build Revision ----- ----- ----- -------- 5 1 17134 48
Hope that helps, tune in more often to get short and sweet PowerTips!
