The following is what I have used successfully in the past and should reset

1. Open an elevated PowerShell or cmd.exe shell

2. Take ownership to Administrators group:

takeown /F "C:\cygwin" /A /R /D Y

3. Reset all file permissions:

icacls "C:\cygwin" /reset /T /C

4. Reset the file attributes:

attrib -h -r -s "C:cygwin\*" /s
