The scope of this is unknown at this point, but it appears to be rather large.
We currently use native Windows API calls defined in the windows-pr gem. Unfortunately, an FFI version of windows-pr was never released, and therefore the calls we directly make use of are not FFI'd. As such they will need replacement in preparation for x64.
A more exhaustive scan needs to be performed, but for certain, we make direct use of:
Furthermore, there are a number of other gems that rely on `windows-pr`, including
It's possible that newer versions of these gems can be used that no longer rely on the old version of `windows-pr`, but some more work will need to be done to verify.
Fortunately, the windows-pr dependency has been removed from the following gems in the versions mentioned below, so upgrading to these versions and verifying against our tests should take care of the dependencies.
