These two new strings simply map to the original two strings, i.e. no duplication of code paths etc

Actually the Windows API is using a reverse naming system, so I would propose the following changes:
* MY and ROOT become marked as deprecated in both, the source code and all documentation, so in future there won't be any confusion anymore what store these actually do access.
* Following the Windows naming system and make the syntax more logical, I propose the new store names are `Windows:LOCALMACHINE/MY` , `Windows:LOCALMACHINE/ROOT`, `Windows:CURRENTUSER/MY` and `Windows:CURRENTUSER/ROOT`. The colon is commonly well-understood as a separator between schemes and names, and the slash is commonly understood as a path separator. So this new syntax makes usage much cleaner.
