Tips for solving Windows 7 system can't delete folder

Windows
7The reason why you can't delete the folder is that you don't have the Administrator permission, you need permission from Administrators to change this folder. The problem: I want to delete some folders today, the results can not be deleted. I tried other folders, some could be deleted, and some could not be deleted. A lot can't be deleted.

Operation steps

1, select the file or folder you want to delete, right click on the folder-->properties--> switch to " ;Security"tab-->click the "Advanced" button--> at the bottom right to switch to "Owner" tab-->Click the "Edit" button--> In the "Change owner to " box, click on your current username, change the owner of the file to the current username, such as Administrators, and check the "Replace subcontainer and object owner" ; options (folders), all the way to determine, so that you have ownership of the folder.

2, back to the "Security" option in the "group or username" in addition to the Administrators three other options to delete, all clicks OK, ok.
