Summary : Microsoft Scripting Guy, Ed Wilson, talks about understanding Windows PowerShell in Windows 7.
Microsoft Scripting Guy, Ed Wilson, is here. This morning I am sipping a cup of English Breakfast tea, with goji berries , lemon grass, and cinnamon. The taste is quite nice, and because the goji berries are sweet, I do not need to add any sugar or honey to my tea. Goji berries are not indigenous to Charlotte, North Carolina, so I use dried berries that I order with my other herbs and spices. Along with my tea, I am eating some homemade scones that the Scripting Wife made with the goji berries. They are rather lovely.
One of the more common questions I get about Windows PowerShell 3.0 runs something like this,“I have Windows PowerShell 3.0, but I do not see the Get-Disk cmdlet.” (Or words to that effect.) Part of the confusion stems from confusing Windows PowerShell 3.0 with the operating system.
Note For information about installation, refer to Install PowerShell 3.0 on Windows 7 .
For example, in Windows 7, when I install Windows PowerShell 3.0, I have access to 355 cmdlets and functions. To find this information, I first imported all of the modules, and then I used the Get-Command cmdlet to retrieve all functions and cmdlets. This is shown here:
In Windows 8, I do not need to install Windows PowerShell 3.0 because it is part of the operating system. When I import all of the modules and count the number of cmdlets and functions in Windows 8, I come up with 988. The output is shown in the following image.
Note Interestingly enough, the output from $PSVersionTable is a little different in Windows 7 and Windows 8.
Look at the modules
So, where does the difference between Windows PowerShell 3.0 in Windows 7 and In Windows 8 come from? Well, it comes from the modules. In Windows 8, many of the teams at Microsoft created modules to permit remote management of aspects of their configuration. In many cases, this took the form of wrapping various WMI classes that have been part of the operating system for a long time. Therefore, just because I am working in Windows 7, it does not mean that I am unable to use Windows PowerShell to manage it—but it will be a bit more difficult.
So what are the modules that are available in Windows 7 after I install Windows PowerShell 3.0? They are listed here:
PS C:\> Get-Module -list | select name
