Windows Automatic Startup Locations - gHacks Tech News (2024)

The Windows operating system ships with options to run custom files or programs on startup.

That's good on the one hand as it enables users of the operating system to select programs that they want to start with Windows. It is also required for some programs, for instance security software as it is usually necessary that these programs start as early as possible.

But it is also a big nuisance as programs can be added to the startup during installations or even on start.

Since this is often not communicated properly to the user, may not only delay system start but also mean that programs that may not be needed all the time are run all the time.

While you can use a program like the excellent Autoruns to manage all startup locations, you sometimes may need direct access to them, for instance when you want to add a program of your own to the startup.

First time users may be overwhelmed by the sheer number of autostart locations -- both as folders on a drive and in the Windows Registry -- and it may take a long time to go through the listing the first time you open it.

Part of why the system is quite complex is the fact that Windows maintains autostart entries for individual users and all users on the system, and if a 64-bit version of Windows is used, another exclusive for 64-bit versions.

Windows Automatic Startup Locations can be divided into the three groups folders, Registry and scheduled Tasks for the most part even though you may also use the Group Policy to add autostart programs to the system (which are reflected in the Windows Registry however).

Windows Automatic Startup Locations: Folders

The following locations are ideal when it comes to adding custom programs to the autostart. Also, it is rather easy to remove program and shortcuts from those autostart folders.

To make things easier, Microsoft has added keywords for the folders which help you open them quickly. The locations / keywords open the same folder.

Autostart folder of the current user

• shell:startup
• %appdata%\Microsoft\Windows\Start Menu\Programs\Startup
• C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Autostart folder of all users

• shell:common startup
• %programdata%\Microsoft\Windows\Start Menu\Programs\Startup
• C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp

Windows Automatic Startup Locations: Registry

The bulk of autostart locations is found in the Windows Registry. You probably know how to load the Registry editor but if you don't, here is how it is done:

1. Tap on the Windows-key, type regedit.exe and hit enter.
2. Confirm the UAC prompt that is displayed.

• HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce (runs the program/command only once, clears it as soon as it is run)
• HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnceEx (runs the program/command only once, clears it as soon as execution completes)
• HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices

Run keys (machine, all users)

• HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
• HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run (only on 64-bit systems)

• HKLM\System\CurrentControlSet\Services
• HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
