Windows 7 ah System file te bangci phiat ding

Open an administrator command prompt by typing cmd into the start menu search box, and hit the Ctrl+Shift+Enter key combination. (Run as administrator)

To take ownership of the file, you’ll need to use the takeown command. Here’s an example:

takeown /f C:\Windows\System32\en-US\winload.exe.mui

That will give you ownership of the file, but you still have no rights to delete it. Now you can run the cacls command to give yourself full control rights to the file:

cacls C:\Windows\System32\en-US\winload.exe.mui /G zocia:F

Note: zocia pen nangma' user name tawh laih ding
