Win8系统和win7一样，默认没有内置的系统管理员权限，导致很多用户在使用或访问应用程序时提示“需要管理员权限才能访问”。那么如何打开系统管理员权限呢？
如何打开Win8系统的管理员权限？
1.首先，创建记事本，将下面的代码复制到记事本中，保存为。reg格式，并双击注册表获取管理员权限。
Windows Registry Editor Version 5.00
[-HKEY类根/*/shell/runas]
[HKEY _ Class _ Root/*/Shell/Operation Mode]
@="获得超级管理员权限"
" Icon "=" C://Windows//System32//imageres。dll，-78 "
"Non-working directory"=""
[HKEY类根/*/shell/runas/命令]
@=" cmd。" exe/c takeown/F/" % 1/" icacls/" % 1/"/grant administrator s:F "
“隔离命令”=“cmd。" exe/c takeown/F/" % 1/" icacls/" % 1/"/grant administrator s:F "
[-HKEY class root directory/directory/shell/running mode]
[HKEY _ Class _ Root/Directory/Shell/Run Mode]
@="获得超级管理员权限"
" Icon "=" C://Windows//System32//imageres。dll，-78 "
"Non-working directory"=""
[HKEY class root directory/directory/shell/operation mode/command]
@=" cmd。/F/" % 1/"/r/d y icacls/" % 1/"/grant administrator s:F/t "
“隔离命令”=“cmd。/F/" % 1/"/r/d y icacls/" % 1/"/grant administrator s:F/t "
[-HKEY类根/dllfile/shell]
[HKEY类_根/dllfile/shell/runas]
@="获得超级管理员权限"
" HasLUAShield"=" "
"Non-working directory"=""
[HKEY类根/dllfile/shell/runas/command]
@=" cmd。" exe/c takeown/F/" % 1/" icacls/" % 1/"/grant administrator s:F "
“隔离命令”=“cmd。" exe/c takeown/F/" % 1/" icacls/" % 1/"/grant administrator s:F "
[-HKEY class root directory/drive/shell/running mode]
[HKEY _ Class _ Root/Drive/Shell/Operation Mode]
@="获得超级管理员权限"
" Icon "=" C://Windows//System32//imageres。dll，-78 "
"Non-working directory"=""
[HKEY _ Class _ Root/Drive/Shell/Operation Mode/Command]
@=" cmd。/F/" % 1/"/r/d y icacls/" % 1/"/grant administrator s:F/t "
“隔离命令”=“cmd。/F/" % 1/"/r/d y icacls/" % 1/"/grant administrator s:F/t "
2.删除管理员权限。按照上面的步骤复制代码创建一个新的记事本并粘贴到记事本中，另存为。reg格式，双击删除管理员权限。
