Autostart, or startup programs, are applications, services and scripts set to run automatically when the system boots or a user signs in. They register themselves in places such as the Windows Startup folder, Task Manager's Startup tab, macOS Login Items or Linux autostart entries and systemd services.
Why it matters
Every autostart entry consumes memory and processor time and lengthens the time before the computer is ready. Many installers add chat clients, updaters or launchers without asking. Reviewing the list is one of the most effective ways to speed up an older machine. Autostart locations are also used by malware to survive reboots, so unfamiliar entries should be checked.
Example
On Windows 11, open Task Manager, go to Startup apps and sort by Startup impact. Disabling a "High" entry such as a game launcher can shave seconds from boot without uninstalling it. On macOS, go to System Settings, General, Login Items. On Linux with systemd, systemctl disable bluetooth stops that service starting at boot.
Common mistakes
- Disabling security software, drivers or touchpad utilities that need to run at startup.
- Assuming "disabled" means removed; the app still sits on disk.
- Forgetting that many apps re-enable their autostart entry after updating.
