Policypak offers a software whitelist option which helps us to answer the Windows 10 question of 'what to do with the Microsoft Store' issue. This alone was a major point for my company.
Much of what is done in Policypak can be done through native Group Policy, however it would take consistent staff, training, manpower and trial & error to make this happen as well as a lot of doing to make some of the things PolicyPak does naturally in order to work. Policypak gives you a very nice GUI based product that is simple, the management is where it shines - often using Item Level Targeting (ILT) in creative ways that are not available in native Group Policy. It's worked magic in the sense that it can rework group policy to an almost new-like product. A product much easier to work with, you spend your time coming up with meaningful policies and where to apply them instead of just figuring out how to make those policies actually work and apply as they are supposed to. I want to re-iterate here, crossing over computer/user policies is very much a thing in PolicyPak and yes you can do those things in native GP often, it can take hours to make a policy work properly to do that, where it takes minutes and is very straightforward in PolicyPak.
Boiling down group policy into gui-driven simplicity greatly simplifies the building, testing, and management of group policies. Team up with AGPM and it becomes a great powerhouse.
It is often updated. A lot, every 1-2 weeks or so. And it would be best to keep up to date.
I've taken the GP Master class which delves into Group Policy, and PolicyPak and appreciate the product a little more after taking the class. As a new AD Administrator I was on the right track, but avoided even having to learn painful things because PolicyPak's administration is so much simpler. It would be difficult and incredibly painful to administrate our company as a single admin with hands-on without the product and I've come to appreciate that.
*Trainings - The PolicyPak people are consistently releasing webinars/videos, and they are available for a signup on a weekly basis. They are largely the same ones, but they will get you started. Some things you will have to ask, or check the fleshed out forumn or knowledge base which is available to customers and a wealth of resources. Review collected by and hosted on G2.com.
