Question

I have a small application with a CheckBox option that the user can set if they want the app to start with Windows.

My question is how do I actually set the app to run at startup.

ps: I’m using C# with .NET 2.0.

Answer 1

Several options, in order of preference:

1. Add it to the current user’s Startup folder. This requires the least permissions for your app to run, and gives the user the most control and feedback of what’s going on. The down-side is it’s a little more difficult determining whether to show the checkbox already checked next time they view that screen in your program.
2. Add it to the HKey_Current_User\Software\Microsoft\Windows\CurrentVersion\Run registry key. The only problem here is it requires write access to the registry, which isn’t always available.
3. Create a Scheduled Task that triggers on User Login
4. Add it to the HKey_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run registry key. The only problem here is it requires write access to the registry, which isn’t always available.
5. Set it up as a windows service. Only do this if you really mean it, and you know for sure you want to run this program for all users on the computer.

This answer is older now. Since I wrote this, Windows 10 was released, which changes how the Start Menu folders work… including the Startup folder. It’s not yet clear to me how easy it is to just add or remove a file in that folder without also referencing the internal database Windows uses for these locations.
