Where do you find full list of Windows PowerShell MVPs? Turns out that if you go to the Microsoft MVP Awardees page PowerShell is not in the category list. The trick is to pick the Windows Server – Admin Frameworks specialization – and here you’ll find all the PowerShell MVPs.
As of today there are 24 MVPs in the list. It is hard to tell whether they all are PowerShell folks or there are other MVPs to fall under the category (e.g. MMC). Maybe you just need to look through the biographies in the profiles to learn more. But at least 24 is not too big of a number to find who you need.
