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。

#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"
}

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).

工作示例
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. End! pause>nul goto :eof :requirePrivilegies set guid=%random%%random%-%random%-%random%-%random%-%random%%random%%random% mkdir %WINDIR%\%guid%>nul 2>&1 rmdir %WINDIR%\%guid%>nul 2>&1 IF NOT %ERRORLEVEL%==0 ( echo ########## ERROR: ADMINISTRATOR PRIVILEGES REQUIRED ########### echo # This script must be run as administrator to work properly! # echo # Right click on the script and select "Run As Administrator" # echo ############################################################### pause>nul exit ) goto :eof
本页中四个看似最兼容的方法的集合。第一个真的很天才。从XP开始测试。令人困惑的是,没有标准的命令可以检查管理权限。我猜他们现在只是专注于PowerShell,这对于我自己的大部分工作来说都是无用的。
我把这个批处理称为“exit-if-not-admin”。Cmd `可以从其他批中调用,以确保如果没有给定所需的管理权限,它们不会继续执行。

#check for local role
$identity = New-Object Security.Principal.WindowsIdentity($env:UserName)

Write-Host "IsInRole('$Role'): " $principal.IsInRole($Role)

whoami /groups在一种情况下不起作用。如果你已经完全关闭了UAC(不仅仅是关闭了通知),并且你从一个管理员提示开始,然后发出:
runas /trustlevel:0x20000 cmd
你将运行非提升,但发出:
whoami /groups
会说你升职了。这是错误的。这就是为什么它是错误的:
当在这种状态下运行时,如果IsUserAdmin (https://msdn.microsoft.com/en-us/library/windows/desktop/aa376389(v=vs.85).aspx)返回FALSE并且UAC完全禁用,并且GetTokenInformation返回TokenElevationTypeDefault (http://blogs.msdn.com/b/cjacks/archive/2006/10/24/modifying-the-mandatory-integrity-level-for-a-securable-object-in-windows-vista.aspx),那么进程不是在运行elevated,但是whoami /groups声称它是。
实际上,从批处理文件中做到这一点的最好方法是:
net session >nul 2>nul
net session >nul 2>nul
echo %errorlevel%
你应该做两次net session,因为如果有人事先做了at,你会得到错误的信息。
@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
