    1. Windows Registry Editor Version 5.00
    2. [HKEY_CLASSES_ROOT\*\shell\runas]
    3. @="管理员取得所有权"
    4. "NoWorkingDirectory"=""
    5. [HKEY_CLASSES_ROOT\*\shell\runas\command]
    6. @="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
    7. "IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
    8. [HKEY_CLASSES_ROOT\exefile\shell\runas2]
    9. @="管理员取得所有权"
    10. "NoWorkingDirectory"=""
    11. [HKEY_CLASSES_ROOT\exefile\shell\runas2\command]
    12. @="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
    13. "IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
    14. [HKEY_CLASSES_ROOT\Directory\shell\runas]
    15. @="管理员取得所有权"
    16. "NoWorkingDirectory"=""
    17. [HKEY_CLASSES_ROOT\Directory\shell\runas\command]
    18. @="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"
    19. "IsolatedCommand"="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"

    取消管理员权限：

    6. [HKEY_CLASSES_ROOT\*\shell\runas-\command] 
    7. @="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
    8. "IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /reset && cacls \"%1\" /e /r \"%%USERNAME%%\""
