Why programs launch automatically and how to stop them

When you turn on your computer, you may notice that certain programs open on their own — Spotify, Discord, Slack, antivirus software, or others you installed months ago. These programs are set to launch at startup, which means Windows or Mac has been told to open them every time you boot up. You can remove any of them from this automatic launch list without uninstalling the program itself.

Stopping a program from starting automatically frees up memory and processing power, makes your computer boot faster, and gives you a cleaner desktop when you log in. The steps differ depending on whether you use Windows or Mac, but both let you control the startup list directly from your system settings.

Key Takeaways

  • Programs set to launch at startup are listed in your system settings, and you can disable them without uninstalling anything.
  • On Windows 11, open Task Manager, go to the Startup tab, right-click any program, and select Disable.
  • On Windows 10, the process is the same: Task Manager, Startup tab, right-click, Disable.
  • On Mac, go to System Settings, General, Login Items, select the program, and click the minus button.
  • Disabling a startup program does not delete it — you can still open it manually whenever you want.

How to disable startup programs on Windows 11

Open Task Manager by right-clicking the taskbar at the bottom of your screen and selecting Task Manager from the menu. If that does not work, press Ctrl + Shift + Esc on your keyboard, which opens Task Manager directly.

Once Task Manager is open, look for the Startup tab at the top. Click it. You will see a list of all programs currently set to launch when Windows starts. Each one shows a Status column that says either Enabled or Disabled.

Find the program you want to stop. Right-click on it and select Disable from the menu. The Status will change to Disabled immediately. Close Task Manager. The next time you restart your computer, that program will not open automatically.

You can disable as many programs as you want this way. A common mistake is disabling programs you do not recognize — if you are unsure what something is, leave it alone or search for the program name online before disabling it. Some programs (like antivirus software) are meant to run at startup for your security.

How to disable startup programs on Windows 10

The process on Windows 10 is identical to Windows 11. Open Task Manager by right-clicking your taskbar or pressing Ctrl + Shift + Esc.

Click the Startup tab. Find the program you want to disable, right-click it, and select Disable. Close Task Manager and restart your computer to confirm the change took effect.

If you do not see a Startup tab, your version of Windows 10 may be older. In that case, press Windows key + R, type msconfig, and press Enter. Go to the Startup tab in the window that opens. Uncheck any program you want to disable, click Apply, then OK. Restart your computer.

How to disable startup programs on Mac

Click the Apple menu in the top-left corner of your screen and select System Settings. On older Macs running Monterey or earlier, this is called System Preferences.

In System Settings, click General in the left sidebar. Then click Login Items. You will see a list of programs set to open when you log in.

Select the program you want to stop from launching automatically. Click the minus button (−) below the list. The program disappears from the startup list. Close System Settings. The next time you restart your Mac, that program will not open.

If you want to re-enable a program later, open System Settings again, go to General > Login Items, click the plus button (+), find the program in your Applications folder, and click Add.

What happens when you disable a startup program

Disabling a program from startup does not uninstall it, delete any of its files, or change how it works. It only prevents that program from opening automatically when your computer starts. You can still open the program manually by clicking its icon, searching for it in your Start menu, or double-clicking its file.

The program will remember all your settings, passwords, and data exactly as they were. The only difference is that you now control when it launches instead of it launching on its own.

If you change your mind and want a program to start automatically again, you can re-enable it using the same steps: Task Manager on Windows or System Settings on Mac.

Programs you should think twice about disabling

Some programs are set to launch at startup for a reason. Antivirus software, Windows Defender, and security tools should usually stay enabled so they run in the background and protect your computer. If you disable them, your computer may be vulnerable to threats.

Similarly, if you use a password manager like 1Password or Bitwarden, keeping it in startup can make logging into websites faster. Cloud storage programs like OneDrive or Google Drive may need to run at startup to sync your files automatically.

Before disabling anything, ask yourself whether you want that program running in the background. If you are unsure what a program does, search for its name online or leave it enabled. You can always disable it later if you decide you do not need it.

Frequently Asked Questions

Will disabling a startup program slow down my computer?

No. Disabling a startup program will not slow down your computer — it will actually make it faster. Fewer programs running at startup means your computer uses less memory and processing power when it boots up, so you reach your desktop more quickly.

Can I disable multiple programs at once?

On Windows, you can disable them one at a time through Task Manager. On Mac, you can select multiple programs in Login Items by holding Ctrl and clicking each one, then click the minus button to remove them all at once.

What if I disable a program and my computer stops working properly?

Re-enable the program using the same steps you used to disable it. Open Task Manager or System Settings, find the program in the startup list, and select Enable or click the plus button to add it back. Restart your computer and the problem should resolve.

Do I need to restart my computer for the change to take effect?

Yes. The startup list only runs when your computer boots up, so you need to restart for the change to take effect. Simply closing Task Manager or System Settings is not enough — you must restart your computer.

Can I see what each startup program does before I disable it?

In Task Manager on Windows, right-click a program and select Open file location to see where it is stored, or search for the program name online to learn what it does. On Mac, you can search for the program name in Spotlight to find information about it.
