Technet has a nice article (Windows PowerShell for Windows Server 2012 and Windows 8) listing a myriad of PowerShell cmdlets available on the latest OSes. Often there are easy (or not so easy:-) ways to backport some of those to earlier OSes. In particular I am interested in installing the MSMQ cmdlets in Windows 7. Can this be done and if so how? My searches thusfar have drawn a blank.
I don't think this is an option. I believe it's specific to PowerShell 4 on Server 2012 / Windows 8. I couldn't find a separate installation for the MSMQ PowerShell module, but when I selected the MSMQ Server feature on my Server 2012 box and installed it, the MSMQ module became available.
