Förhöjda privilegier i batchfiler

Begär höjda privilegier i en genväg

Många uppgifter kräver förhöjda privilegier. Du kan höja användarrättigheterna till administratörsnivå för din buntkörningstid med en genväg:

1. Tryck på alt + och batchfilen till en vald mapp för att skapa en genväg.

2. Högerklicka och välj "Egenskaper".

3. Välj fliken "Genväg".

4. Klicka på "Avancerat".

   

5. Aktivera "Kör som administratör".

   

6. Klicka på "OK" två gånger.

Begär förhöjda privilegier vid Runtime

Följande batchfil kommer att visa en UAC-promp så att du kan acceptera förhöjda administratörsbehörigheter för batch-sessionen. Lägg till din uppgiftskod i :usercode , så att de körs med förhöjda privilegier.

@echo off
setlocal EnableDelayedExpansion
:: test and acquire admin rights
cd /d %~dp0 & echo/
if not "%1"=="UAC" (
    >nul 2>&1 net file && echo Got admin rights || (echo No admin rights & ^
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute("%~snx0", 'UAC', '', 'runas', 1);close();"))
:: re-test admin rights
echo/ & >nul 2>&1 net file && (echo Got admin rights & echo/) || (echo No admin rights. Exiting... & goto :end)

:usercode
:: add your code here
echo Performing admin tasks
echo Hello >C:\test.txt

:end
timeout /t 5 >nul
exit /b    

Begär förhöjda runtime-privilegier utan UAC-prompt

Som tidigare exempel begär detta skript höjning om det behövs. Vi ber användaren om referenser för att undvika UAC-prompten.
