How to determine Windows Agent version

Hello!

We are trying to identify the Windows Agent version(s) in our environment so that we can upgrade any below v7.3 prior to implementing AM 8.4, per the Read Me.

Our SCCM team used this thread to create a collection, but it only came back with a handful of results from 1 specific OS, which I don't think is correct. https://community.rsa.com/thread/196921

I created a case and was asking what is the best method for determining agent version and was told either manually 1x1 (Which we can't do) or using that thread I supplied. So I just wanted to get additional verification that this is still the best process since I don't believe our results are accurate.

Thanks!
