Following a discussion started here, I am releasing this Product Policy viewer.
It can read both an online and offline registry.
It will parse the following key : SYSTEM\CurrentControlSet\Control\ProductOptions\ProductPolicy.
What is good for?
Check enabled/disabled features on your windows (depending on which version you have).
I am asking the modos over here if adding a write feature to this tool would be considered as encouraging illegal activities.
Note that I did not check yet is writing to an offline registry is actually an option.
