Get PowerShell Version?

How can I find out the powershell version to find out if it's RC or
Final?

[ydroam]

Found Windows PowerShell under Windows XP - Software Updates. It would
say RC if it was right?

I put this in my profile:
function Ver { get-host | select version }

I was thinking this as well. There should be some text field beyond version
that would explicitly show (CTP1, Beta1, Beta2, RTM, etc). The build
numbers don't mean much as you have to track them down and figure it out
each time.

Even better ;p

function Ver { $host.Version }

OK since someone brought this up. Which is the more important/useful
version number and in which context?

24> $host.Version
Version
-------
1.0.0.0

25> (gcm "$PSHome\PowerShell.exe").FileVersionInfo.ProductVersion
6.0.5430.0

Hi,

I wish a very Happy and Prosporous New Year to you all !!

Most installers use fileversion while updating a binary (as part of a QFE).
For example Windows update updates a binary only if the fileversion in QFE
is greater than the one on disk :-

1. Lets say an assembly (x.dll) with fileversion 2.0.0.0 is installed on a
machine.
Lets say there are 2 QFEs available for x.dll binaray:- QFE1 x.dll's
fileversion is 1.1.0.0 and QFE2 x.dll's fileversion is 2.1.0.0

Only QFE2 will update x.dll on the machine since its fileversion is greater
than the one on the disk.

For managed(CLR) assemblies there are 2 version numbers: AssemblyVersion and
FileVersion. Assembly version is used by the CLR loader / linker.
Installation technolgies might use both or just FileVersion.

Which one is most important:

It depends on the product you are working with and the scenarios. For
PowerShell, you may never need to know the fileversion number. To
distinguish between RC2 and RTM builds of Powershell use the following
registry information:

To check if PowerShell is installed use:

HKLM\Software\Microsoft\PowerShell\1 Install ( = 1 )

To check if RC2 or RTM is installed use:

HKLM\Software\Microsoft\PowerShell\1 PID (=89393-100-0001260-00301) -- For
RC2
HKLM\Software\Microsoft\PowerShell\1 PID (=89393-100-0001260-04309) -- For
RTM
