How do I stop a desktop app from launching every time I sign in?

Identify the app first, then look for its entry in the startup or login-items controls for your computer. Change only that entry, not several items at once. Before making a change, note the app’s name, where you found the setting, and its original state. That will help you locate it again if you need to restore it.

If the app is not in the system list, check its own preferences for an automatic-launch option. The exact location and wording can vary by app.

Windows provides startup-app controls in Settings and Task Manager. Apps placed in the Startup folder can also run when a user signs in. Review the entry and disable only the one you have identified as the app you want to stop. [S1]

A cautious sequence is:

1. Open the startup-app list in Settings or Task Manager.
2. Find the entry that matches the app’s name.
3. Check that you have the intended entry before changing it.
4. Disable that entry using the available control.

If you cannot identify an entry, leave it unchanged. If the app is not in the list, check its own preferences for an automatic-launch setting.

On Mac, go to System Settings > General > Login Items & Extensions. The list includes items that can open automatically at login. Select the intended item and use the remove control to stop it opening automatically. [S2]

If you want a temporary test rather than a lasting change, Apple describes holding Shift during login to prevent login items from opening at the next login. [S2] If the app continues to open on later sign-ins, check its own preferences: not every app-specific launch setting is necessarily managed in the system list. [S2]

Use your note to return to the same control and restore the app’s entry if the available settings allow it. The Windows guidance covers managing startup behavior but does not give one restoration procedure for every control or app. The Mac guidance describes removing an item but does not specify how to re-enable every possible item. [S1] [S2]

For example, your note could say: “App: [name]. Setting location: [Settings, Task Manager, Login Items, or app preferences]. Original state: enabled. Change: disabled. Reason: opens at sign-in.” If you need the app to launch again, use the note to find the same setting and follow the control available there. If you cannot identify the right entry, avoid changing unrelated items.

1. Identify the app and note its name.
2. Check the operating system’s startup or login-items list.
3. If it is absent, check the app’s preferences for an automatic-launch option.
4. Record the setting’s location and original state.
5. Change only the intended entry.
6. If a needed workflow is disrupted, use your note to find the same control and restore the entry where possible.

The exact controls and restoration steps depend on the app and system. The Windows and Mac instructions above describe the supported system controls, not every app-specific setting. [S1] [S2]
