Verhoogde rechten in batchbestanden

Verzoeken om verhoogde bevoegdheden in een snelkoppeling

Veel taken vereisen verhoogde rechten. U kunt gebruikersrechten naar beheerdersniveau brengen voor uw batch-runtime met een snelkoppeling:

1. Druk op alt + en het batchbestand naar een geselecteerde map om een snelkoppeling te maken.

2. Klik met de rechtermuisknop en selecteer "Eigenschappen".

3. Selecteer het tabblad "Snelkoppeling".

4. Klik op "Geavanceerd".

   

5. Schakel "Als administrator uitvoeren" in.

   

6. Klik tweemaal op "OK".

Verhoogde rechten aanvragen tijdens runtime

In het volgende batchbestand verschijnt een UAC-prompt waarmee u verhoogde beheerdersrechten voor de batchsessie kunt accepteren. Voeg uw :usercode aan :usercode van de batch, zodat ze met verhoogde rechten worden uitgevoerd.

@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    

Runtime verhoogde rechten aanvragen zonder UAC-prompt

Als vorig voorbeeld vraagt dit script om verhoging indien nodig. We vragen de gebruiker om inloggegevens om de UAC-prompt te vermijden.
