How to stop apps from opening on startup

Apps that start when you sign in slow down startup and use memory in the background. Turning them off does not uninstall anything: you can still open them yourself, and turn them back on at any time.

Time
A few minutes
Level
Easy
You need
Nothing. Some entries can be changed only from an administrator account.

Before you start

  • Keep your antivirus and anything you use every day (cloud sync, password manager) turned on.
  • If you do not know what an entry is, leave it on and look up the name first.

Windows 11

Steps written for Windows 11 24H2, 25H2 and 26H2.

  1. Open the Startup settings

    Select Start > Settings > Apps > Startup.

    Settings, Apps, Startup with the list of startup apps and their On/Off switches
    Each app has its own switch and its startup impact. Screenshot: Windows 11 26H2
  2. Turn apps off

    Set the switch of each app you do not need at sign-in to Off. Use Sort by to put the apps with the highest impact first.

  3. Or use Task Manager

    Right-click Start, select Task Manager, then Startup apps. Select an app and select Disable. Task Manager shows the same list with more detail, such as the publisher.

    Select an app, then Disable. Screenshot: Windows 11 26H2
  4. Restart to check

    Restart the PC. The apps you turned off no longer open by themselves.

What the startup impact means

ImpactMeaning (Microsoft)
HighMore than 1 second of CPU time or more than 3 MB of disk reads at startup.
MediumBetween 300 milliseconds and 1 second of CPU time, or between 292 KB and 3 MB of disk reads.
LowLess than 300 milliseconds of CPU time and less than 292 KB of disk reads.
Not measuredNo data yet; the app is turned on.
NoneThe app is turned off.

If an app is not in the list

Apps that are not registered with Windows can start from the Startup folder. Right-click Start, select Run, type shell:startup (your account) or shell:common startup (all accounts) and press Enter. Delete the app's shortcut from that folder; the app itself stays installed.

If an entry reads We couldn't find this app, the program was removed or sits on a drive that is not connected. Reinstall it, or remove the leftover entry.

If an app keeps coming back

Some apps turn their own startup back on. Look for an option such as start with Windows or open at login in the app's own settings and turn it off there. If you do not need the app at all, uninstall it: Uninstall a program or app in Windows. If you never installed it, check it for unwanted software: Remove a browser extension On 2-Spyware.
