For cygwin setup I have 

install for "all users"

root directory c:\cygwin

package directory c:\cygwin\pk  <-- perhaps not a default but never been an issue before or for any other packages.



Other packages install e.g. xxd installs


C:\cygwin\bin>dir ddrescue.exe
 Volume in drive C has no label.
