Update it to the version found at https://github.com/Microsoft/Windows-classic-samples , which is in an MIT licensed repo, and add the LICENSE file (edited to remove the SIL Open Font LICENSE part since that doesn't apply). Some modifications have been made to reduce the diff/stop git complaining (not including any file that wasn't in the previous version and removing the related header includes in streams.h, and fixing some but not all of the whitespace issues).
