Introduction
By default PowerShell version 2 is available in 2008 R2 & Windows 7.
There is an document available for upgrading the PowerShell version on TechNet: https://technet.microsoft.com/en-us/library/hh847837.aspx.
There are so many reasons for upgrading the PowerShell version; we will discuss that later into this space. For Windows 2008 R2 almost the same steps can be taken for Windows 7 but Windows management framework is different for Win7. See the below link for supported OS.

Prerequisites:
- SP1-Windows 2008 R2

Here .NET framework is an important component for PowerShell version 4. Here is the link for getting to know for .NET framework version.
How to Determine Which .NET Framework Versions Are Installed
Below components are .NET 4.5.1 & WMF 4.
Installing the .NET Framework
Installing the WMF 4
Now reboot that box.
Checking the PowerShell version
Need to run powershell -version 4.0 for working with PS version 4. Check the PS version $psversiontable . You can see 4 is compatible with 3, 2 & 1
Install ISE
We now need to install the ISE for installing the version WMF 4.
If we have installed WMF 4, ISE will be installed in background.
Manual installation of ISE is not required.
