How to run a program automatically as admin on Windows 7 at startup

Question

I created my own parental control app to monitor my kids activity  The app s only GUI is a task bar icon  The program is installed as admin  I d like this program to be started up automatically as admin user on Windows startup  so that standard users cannot kill it from task manager    I can create a registry key at   HKLM Software Microsoft Windows CurrentVersion Run   to make it run automatically when Windows starts up  The problem is that the program is started as the logged in  standard  user   How can I make it run in an elevated mode  Is this possible at all in Win7

Setting compatibility of your application to administrator  Run theprogram as an administrator     Plug it into task scheduler  then turn off UAC

This is not possible  However  you can create a service that runs under an administrative user   The service can run automatically at startup and communicate with your existing application  When the application needs to do something as an administrator  it can ask the service to do it for it   Remember that multiple users can be logged on at once

You should also consider the security implications of running a process as an administrator level user or as Service  If any input is not being validated properly  such as if it is listening on a network interface  If the parser for this input doesn t validate properly  it can be abused  and possibly lead to an exploit that could run code as the elevated user  in abatishchev s example it shouldn t be much of a problem  but if it were to be deployed in an enterprise environment  do a security assessment prior to wide scale deployment

You can do this by installing the task while running as administrator via the TaskSchedler library  I m making the assumption here that  NET C  is a suitable platform language given your related questions   This library gives you granular access to the Task Scheduler API  so you can adjust settings that you cannot otherwise set via the command line by calling schtasks  such as the priority of the startup  Being a parental control application  you ll want it to have a startup priority of 0  maximum   which schtasks will create by default a priority of 7   Below is a code example of installing a properly configured startup task to run the desired application as administrator indefinitely at logon  This code will install a task for the very process that it s running from      Copyright    2017 Jesse Nicholson   This Source Code Form is subject to the terms of the Mozilla Public License  v  2 0  If a copy of the MPL was not distributed with this file  You can obtain one at http   mozilla org MPL 2 0            lt summary gt      Used for synchronization when creating run at startup task       lt  summary gt  private ReaderWriterLockSlim m runAtStartupLock   new ReaderWriterLockSlim     public void EnsureStarupTaskExists         try               m runAtStartupLock EnterWriteLock              using var ts   new Microsoft Win32 TaskScheduler TaskService                             Start off by deleting existing tasks always  Ensure we have a clean current install of the task              ts RootFolder DeleteTask Process GetCurrentProcess   ProcessName  false                   Create a new task definition and assign properties             using var td   ts NewTask                                  td Principal RunLevel   Microsoft Win32 TaskScheduler TaskRunLevel Highest                     This is not normally necessary  RealTime is the highest priority that                    there is                  td Settings Priority   ProcessPriorityClass RealTime                  td Settings DisallowStartIfOnBatteries   false                  td Settings StopIfGoingOnBatteries   false                  td Settings WakeToRun   false                  td Settings AllowDemandStart   false                  td Settings IdleSettings RestartOnIdle   false                                      td Settings IdleSettings StopOnIdleEnd   false                  td Settings RestartCount   0                                      td Settings AllowHardTerminate   false                  td Settings Hidden   true                  td Settings Volatile   false                  td Settings Enabled   true                  td Settings Compatibility   Microsoft Win32 TaskScheduler TaskCompatibility V2                  td Settings ExecutionTimeLimit   TimeSpan Zero                   td RegistrationInfo Description    Runs the content filter at startup                        Create a trigger that will fire the task at this time every other day                 var logonTrigger   new Microsoft Win32 TaskScheduler LogonTrigger                    logonTrigger Enabled   true                                      logonTrigger Repetition StopAtDurationEnd   false                  logonTrigger ExecutionTimeLimit   TimeSpan Zero                  td Triggers Add logonTrigger                       Create an action that will launch Notepad whenever the trigger fires                 td Actions Add new Microsoft Win32 TaskScheduler ExecAction Process GetCurrentProcess   MainModule FileName    StartMinimized   null                        Register the task in the root folder                 ts RootFolder RegisterTaskDefinition Process GetCurrentProcess   ProcessName  td                                                     finally               m runAtStartupLock ExitWriteLock

A program I wrote  farmComm  may solve this  I released it as open-source and Public Domain   If it doesn t meet your criteria  you may be able to easily alter it to do so   farmComm    Runs at boot-up under a service  which continues when users log in or out   In Session 0 Under the user  NT AUTHORITY SYSTEM    Spawns arbitrary processes  you choose    Also in Session 0  Invisibly   or without showing any user interface GUI With access to graphics hardware  e g  GPUs   Responds to the active session  even if it changes  including the Secure Desktop  This is how it  Only spawns processes after a user is idle for 8 5 minutes Terminates spawns when a user resumes from idle    The source scripts are available here   https   github com r-alex-hall farmComm

You need to plug it into the task scheduler  such that it is launched after login of a user  using a user account that has administrative access on the system  with the highest privileges that are afforded to processes launched by that account   This is the implementation that is used to autostart processes with administrative privileges when logging in as an ordinary user   I ve used it to launch the  OpenVPN GUI  helper process which needs elevated privileges to work correctly  and thus would not launch properly from the registry key   From the command line  you can create the task from an XML description of what you want to accomplish  so for example we have this  exported from my system  which would start notepad with the highest privileges when i log in    lt  xml version  1 0  encoding  UTF-16   gt   lt Task version  1 2  xmlns  http   schemas microsoft com windows 2004 02 mit task  gt     lt RegistrationInfo gt       lt Date gt 2015-01-27T18 30 34 lt  Date gt       lt Author gt Pete lt  Author gt     lt  RegistrationInfo gt     lt Triggers gt       lt LogonTrigger gt         lt StartBoundary gt 2015-01-27T18 30 00 lt  StartBoundary gt         lt Enabled gt true lt  Enabled gt       lt  LogonTrigger gt     lt  Triggers gt     lt Principals gt       lt Principal id  Author  gt         lt UserId gt CHUMBAWUMBA Pete lt  UserId gt         lt LogonType gt InteractiveToken lt  LogonType gt         lt RunLevel gt HighestAvailable lt  RunLevel gt       lt  Principal gt     lt  Principals gt     lt Settings gt       lt MultipleInstancesPolicy gt IgnoreNew lt  MultipleInstancesPolicy gt       lt DisallowStartIfOnBatteries gt false lt  DisallowStartIfOnBatteries gt       lt StopIfGoingOnBatteries gt false lt  StopIfGoingOnBatteries gt       lt AllowHardTerminate gt true lt  AllowHardTerminate gt       lt StartWhenAvailable gt false lt  StartWhenAvailable gt       lt RunOnlyIfNetworkAvailable gt false lt  RunOnlyIfNetworkAvailable gt       lt IdleSettings gt         lt StopOnIdleEnd gt true lt  StopOnIdleEnd gt         lt RestartOnIdle gt false lt  RestartOnIdle gt       lt  IdleSettings gt       lt AllowStartOnDemand gt true lt  AllowStartOnDemand gt       lt Enabled gt true lt  Enabled gt       lt Hidden gt false lt  Hidden gt       lt RunOnlyIfIdle gt false lt  RunOnlyIfIdle gt       lt WakeToRun gt false lt  WakeToRun gt       lt ExecutionTimeLimit gt PT0S lt  ExecutionTimeLimit gt       lt Priority gt 7 lt  Priority gt     lt  Settings gt     lt Actions Context  Author  gt       lt Exec gt         lt Command gt  c  windows system32 notepad exe  lt  Command gt       lt  Exec gt     lt  Actions gt   lt  Task gt    and it s registered by an administrator command prompt using   schtasks  create  tn  start notepad on login   xml startnotepad xml      this answer should really be moved over to one of the other stackexchange sites  as it s not actually a programming question per se

I think that using the task scheduler to autostart programs is not very user friendly  and sometimes it has had side effects for me  e g  tray icon for a program is not added    To remedy this  I have made a program called Elevated Startup that first relaunches itself with administrator privileges  then it launches all files in a directory  Since Elevated Startup is now elevated  all the programs it then launches is also given administrator privileges  The directory is on the start menu next to the classic Startup directory  and works very much the same   You may encounter one UAC dialog when the program relaunches itself  depending on your UAC settings   You can get the program here  https   stefansundin github io elevatedstartup

I think the task scheduler would be overkill  imho   There is a startup folder for win7   C  Users miliu AppData Roaming Microsoft Windows Start Menu Programs Startup  Just create a shortcut for your autostart Applicaton  edit the properties of the shortcut and have it always run as administrator    Your kids could close it of course  but if they are tech-savvy they always find a way to keep you out  I know i did when i was younger   Good luck
