Where is the v2.0 and v3.0 folder for PowerShell?

Question

On my box, I installed PowerShell 2.0, but the $PSHome varialbe always return the path below：

C:\Windows\System32\WindowsPowerShell\v1.0

So, where is the v2.0 or v3.0 folder?

Answer 1

Just like how 64-bit system files in Windows are in System32, all versions of Powershell install into the path that says v1.0. One of the things that MS doesn't seem to learn from. Didn't you wonder that Powershell script files have the extension ps1, psm1 etc?
