Research and planning for improved PDK installer design

The PDK 1.6 installation seems to be taking a long time to install on Windows compared to 1.5

The installation took just over 4 minutes, which doesn't sound long, but when you're waiting, it seems like the install has stalled.

In particular it took 40seconds to check the package patches
