Eu acho que você tem que ter o direito de administração embora! Eu acho que a melhor maneira de fazer isso é clicar com o botão direito do mouse em cmd
e Run as administrator
!
To start off, you need an elevated command prompt which is simply a command prompt opened as administrator. In Windows 8 you can open that by right-clicking the bottom left corner of the screen and selecting Command Prompt (Admin). In Windows 7 and previous, search the main menu for cmd, right-click it and select Open as administrator.
You need two commands now: one to actually take ownership of the file or folder and one to grant yourself access rights. These are the two commands you will want to use:
For folders, use:
takeown /f folder_name /r /d y icacls folder_name /grant username_or_usergroup:F /t /q
For files, use:
takeown /f file_name /d y icacls file_name /grant username_or_usergroup:F /q
The commands basically only differ in a few switches that make the folder procession run recursively. If you want to edit only one folder instead of the whole recursive lot, remove the /r and /t switches from the commands. For more info on the commands, simply enter takeown /? or icacls /? into the command prompt.
If I wanted to take control of my Program Files folder, I'd need to enter the following:
takeown /f "C:\Program Files" /r /d y icacls "C:\Program Files" /grant christian:F /t /q
