删除获取管理员权限的注册表

在每句的开头加上“-”号然后再运行一次就OK了，如下：
Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\*\shell\runas]
@=”管理员授权”
“NoWorkingDirectory”=””
[-HKEY_CLASSES_ROOT\*\shell\runas\command]
@=”cmd.exe /c takeown /f \”%1\” && icacls \”%1\” /grant administrators:F”
“IsolatedCommand”=”cmd.exe /c takeown /f \”%1\” && icacls \”%1\” /grant
administrators:F”
[-HKEY_CLASSES_ROOT\exefile\shell\runas2]
@=”管理员授权”
“NoWorkingDirectory”=””
[-HKEY_CLASSES_ROOT\exefile\shell\runas2\command]
@=”cmd.exe /c takeown /f \”%1\” && icacls \”%1\” /grant administrators:F”
“IsolatedCommand”=”cmd.exe /c takeown /f \”%1\” && icacls \”%1\” /grant
administrators:F”
[-HKEY_CLASSES_ROOT\Directory\shell\runas]
@=”管理员授权”
“NoWorkingDirectory”=””
[-HKEY_CLASSES_ROOT\Directory\shell\runas\command]
@=”cmd.exe /c takeown /f \”%1\” /r /d y && icacls \”%1\” /grant administrators:F /t”
“IsolatedCommand”=”cmd.exe /c takeown /f \”%1\” /r /d y && icacls \”%1\” /grant
administrators:F /t”
