Getting started with PowerShell in Windows 7 SP1
Since we need PowerShell to do this quick little upgrade, and PowerShell comes baked into any version of Windows since Windows 7 SP1, make sure you’ve upgraded the operating system at least that far. In other words, just run Windows Update and install whatever it wants you to install (if anything).
