Windows: Fix VerifyVersionInfo calls

Browse Source 
- Fix the VerifyVersionInfo calls, which we use to test for the OS major
version, to also test for the minor version as well as the service pack
major and minor versions.

MSDN: "If you are testing the major version, you must also test the
minor version and the service pack major and minor versions."
