Could not delete folder on Win7

I had the same problem on Win 7 and this worked for me in command prompt.

Solution 1:

RD/S pathname

 

example:

RD/s C:\Users\Username\Downloads\Music

 

this will delete all files and sub-folders in the folder, including the root folder itself.

 

Solution 2:

 

Run cmd, navigate to C:\ (or other disk, if you have installed it in different path).

step 1: 

takeown /r /d y /f cygwin  　　 　　//This command takes ownership recursive of the folder, without asking anything

step 2: 

icacls cygwin /t /grant Everyone:F   　　 //This command gives Full Access to Everyone recursively in the folder

step 3:

rmdir /s /q cygwin　　　　　　　　　　　　//And finally, the command which deletes it all and removes Cygwin
