如何检查当前批处理脚本是否具有管理权限?
我知道如何使它调用自己与runas,但不知道如何检查管理权限。我所见过的唯一解决方案是粗糙的黑客工作或使用外部程序。好吧,其实我不在乎这是不是一份苦差事,只要它能在Windows XP或更新版本上运行就行。

我有两种检查特权访问的方法,这两种方法都非常可靠,而且几乎在每个windows版本上都非常可移植。
1. 方法
set guid=%random%%random%-%random%-%random%-%random%-%random%%random%%random%
mkdir %WINDIR%\%guid%>nul 2>&1
rmdir %WINDIR%\%guid%>nul 2>&1
IF %ERRORLEVEL%==0 (
ECHO PRIVILEGED!
) ELSE (
ECHO NOT PRIVILEGED!
)
这是最可靠的方法之一,因为它很简单,而且这个非常原始的命令的行为不太可能改变。这不是其他内置CLI工具的情况,比如可以通过管理/网络策略禁用的net session,或者像fsutils这样在Windows 10上改变输出的命令。
*适用于XP及以后
2. 方法
REG ADD HKLM /F>nul 2>&1
IF %ERRORLEVEL%==0 (
ECHO PRIVILEGED!
) ELSE (
ECHO NOT PRIVILEGED!
)
Sometimes you don't like the idea of touching the user disk, even if it is as inoffensive as using fsutils or creating a empty folder, is it unprovable but it can result in a catastrophic failure if something goes wrong. In this scenario you can just check the registry for privileges. For this you can try to create a key on HKEY_LOCAL_MACHINE using default permissions you'll get Access Denied and the ERRORLEVEL == 1, but if you run as Admin, it will print "command executed successfully" and ERRORLEVEL == 0. Since the key already exists it have no effect on the registry. This is probably the fastest way, and the REG is there for a long time. * It's not avaliable on pre NT (Win 9X).
*适用于XP及以后

清除临时文件夹的脚本
@echo off :main echo. echo. Clear Temp Files script echo. call :requirePrivilegies rem Do something that require privilegies echo. del %temp%\*.* echo.

@echo off

set ADMDIR=C:\Users\Administrator
dir %ADMDIR% 1>nul 2>&1
echo [%errorlevel%] %ADMDIR%
if "%errorlevel%"=="0" goto main
:: further checks e.g. try to list the contents of admin folders
:: wherever they are stored on older versions of Windows
echo You need administrator privileges to run this script: %0
echo Exiting...
exit /b

echo Executing with Administrator privileges...
下面尝试在Windows目录中创建一个文件。如果成功,它将移除它。
copy /b/y NUL %WINDIR%\06CF2EB6-94E6-4a60-91D8-AB945AE8CF38 >NUL 2>&1
if errorlevel 1 goto:nonadmin
del %WINDIR%\06CF2EB6-94E6-4a60-91D8-AB945AE8CF38 >NUL 2>&1
:admin
rem here you are administrator
goto:eof
:nonadmin
rem here you are not administrator
goto:eof
请注意,06CF2EB6-94E6-4a60-91D8-AB945AE8CF38是今天生成的GUID,假定它与现有文件名不太可能冲突。
这里有另一个添加到列表中;-)
(尝试在系统位置创建文件)
CD.>"%SystemRoot%\System32\Drivers\etc\_"
MODE CON COLS=80 LINES=25
IF EXIST "%SystemRoot%\System32\Drivers\etc\_" (
DEL "%SystemRoot%\System32\Drivers\etc\_"
ECHO Has Admin privileges
) ELSE (
ECHO No Admin privileges
)
MODE CON重新初始化屏幕,并在没有权限写入系统位置时压制任何文本/错误。
PowerShell有人吗?
param (
[string]$Role = "Administrators"
)
#check for local role
$identity = New-Object Security.Principal.WindowsIdentity($env:UserName)
$principal = New-Object Security.Principal.WindowsPrincipal($identity)
Write-Host "IsInRole('$Role'): " $principal.IsInRole($Role)
#enumerate AD roles and lookup
$groups = $identity::GetCurrent().Groups
foreach ($group in $groups) {
$trans = $group.Translate([Security.Principal.NTAccount]);
if ($trans.Value -eq $Role) {
Write-Host "User is in '$Role' role"
}
}
