When you say latest version i assume you mean ePO 4.6.
In which case there's a 'Applied Policies by Policy Name' report that you can run.
Go to reports and filter by 'policy' and it should be near the top.
It will give you a list of all the policies in ePO and you can drill down to view all the machines that are assigned the policy.
Sorry, this is my shoddy wording,
Yes, it's ePO 4.6, but it's client tasks I'm looking for rather than policies. I found there's a similar report for tasks, so thanks.
