Not fully tested as I do not have full control over the machine I work 
on now, but something along the lines of:
- run
takeown /f c:\cygwin /a /r /d y
cacls c:\cygwin0 /t /g Administrators:F
- delete c:\cygwin in Explorer
should be a start.

1) This is for English versions of Windows only:
/d y (answer "yes") can become /d o("oui"), and perhaps /d j("ja"), /d 
"Administrators" is localized too

http://www.ss64.com/nt/cacls.html says:
"Errors when changing permissions
If a user or group has a permission on a file or folder and you grant a 
second permission to the same user/group on the same folder, NTFS will 
sometimes produce the error message "The parameter is incorrect" To fix 
this (or prevent it happening) revoke the permission first (/e /r) and 
then reapply (/e /g)"

Good night
