Off the top of my head, what you could do is this: - Generate an /etc/passwd entry for your old user SID by hand. Make sure to use an arbitrary weird UID like 98765. - Exit and start an elevated shell. - find . -uid 98765 | xargs chown <newuser name or UID> Analog for the group if necessary. Alternativaly there are tools in the wild to change the SID of a file. But those *might* break Cygwin POSIX ACLs.
