It's not a Windows specific thing. You get exactly the same effect on 
Unix if you install a new system and end up with a different userid 
number for an old user name.

Well, you can just use Cygwin's chown and chmod. They update Windows 
file ownership and permissions perfectly well. If you need to handle 
aspects of the Windows permission system that don't map well to the 
simpler Unix one, you can look into getfacl/setfacl, but if you're only 
trying to get the permissions right from Cygwin's point of view, that 
shouldn't be necessary.
