To stop a registered app from opening automatically when you sign in, go to Start > Settings > Apps > Startup and switch it off. You can also disable it in Task Manager > Startup apps, where you can review its startup-impact rating. If it is missing from both lists, check the Windows Startup folders. These steps control automatic launch at sign-in; they do not necessarily stop an app from doing other work in the background.
Choose the right control for the problem
Windows has separate controls for apps that launch when you sign in and apps that perform background activity when you are not using them. If an app opens by itself after sign-in, change its startup setting. If it does not open but continues to sync, update, or send notifications, look for a background-permission setting instead. Disabling startup does not automatically revoke an app’s background permissions, and changing a background permission is not the same as preventing sign-in launch.
The built-in startup controls apply to Windows 11 and Windows 10. Microsoft ended Windows 10 support on October 14, 2025; after that date, Microsoft says free Windows Update software updates, technical assistance, and security fixes are no longer provided for Windows 10. That support status does not change the startup steps below.

Turn off an app in Windows Settings
Use the Startup list
- Open Start, then select Settings.
- Go to Apps > Startup.
- Find the app you do not want to launch automatically and switch its toggle to Off.
This is the simplest option when the app appears in the list. The change prevents Windows from automatically starting that app when you sign in; it does not uninstall the program or prevent you from opening it yourself.

If the app is not listed
Continue to Task Manager to check its startup list. Microsoft says Settings and Task Manager show the same registered startup-app list, so if the app is absent from both, check the Startup folders described below. Some apps are configured through their own settings or other mechanisms rather than the standard list.
Use Task Manager to disable an app and review its impact
Disable the startup entry
- Open Task Manager with Ctrl+Shift+Esc.
- Select Startup apps.
- Select the app you want to stop from launching automatically, then choose Disable.
Task Manager controls the same registered startup-app list as Settings. Its additional value is the startup-impact information, which can help you compare entries before deciding what to disable. The impact label describes activity associated with startup; it is not a prediction of how many seconds you will save by disabling that app.
What the impact labels mean
Microsoft’s current support guidance defines these labels using the app’s startup CPU and disk activity:

- 256 GB SSD of storage.
- Multitasking is easy with 16GB of RAM
- Equipped with a blazing fast Core i5 2.00 GHz processor.
| Impact | Microsoft’s stated thresholds |
|---|---|
| Low | Total CPU usage under 300 milliseconds and disk usage under 292 kilobytes. |
| Medium | CPU usage under one second but over 300 milliseconds, or disk usage under 3 megabytes but over 292 kilobytes. |
| High | CPU usage over one second, or disk usage over 3 megabytes. |
These are operational thresholds for Task Manager’s labels, not results from a study of typical PCs or a guarantee of a particular boot-time improvement. An app with a high rating may be a poor candidate to disable if you rely on it immediately after signing in; an app with a low rating may still be unnecessary. Choose based on the app’s purpose as well as its impact.
Check the Startup folders when an app is missing
Some apps are launched by shortcuts placed in a Startup folder rather than by an entry in the regular Settings or Task Manager list. Windows provides a folder for your account and another that applies to all users on the PC.
- Press Windows key+R to open Run.
- To open the Startup folder for your account, enter
shell:startupand press Enter. To open the folder for all users, entershell:common startupand press Enter. - Look for a shortcut to the app you want to stop launching. Remove that shortcut from the folder if you do not want it to start automatically.
- If you are unsure which folder contains the shortcut, check both. Removing a shortcut from Startup does not uninstall the app itself.
The current-user folder affects your account; the common Startup folder is for all users. This distinction matters on shared PCs: changing a shortcut in your own Startup folder does not necessarily change startup behavior for other accounts.

Handle “We couldn’t find this app” carefully
A startup entry with the message “We couldn’t find this app” does not necessarily mean Windows or the app installation is broken. Microsoft’s guidance says the entry can be associated with a removable or network drive, a missing path, or an app that has been uninstalled. Inspect the entry’s information before deciding what to do. If it points to software you still use, confirm that its location is available before removing or changing the entry; if the app has been uninstalled, the entry may be stale.
Stop background activity separately
Startup settings determine whether an app launches automatically at sign-in. Background permissions govern certain activity while an app is not in use. Some supported Microsoft Store apps expose a Background app permissions setting. Desktop apps are not governed by that list, according to Microsoft, and should be controlled through the app’s own settings.
The available controls depend on the app and Windows version, so there is not one universal background-permissions path that applies to every program. Check the app’s settings for options related to background activity, syncing, or running when closed. If the issue is specifically that a window appears at sign-in, use the startup controls rather than relying on a background permission.

Which method should you use?
| Method | Use it when | What to know |
|---|---|---|
| Settings > Apps > Startup | You want a quick on/off change for a listed app. | It provides the registered startup-app list and a straightforward toggle. |
| Task Manager > Startup apps | You want to disable a listed app while reviewing startup impact. | It shows the same list as Settings and adds impact information. |
| Startup folders | The app is absent from the standard startup list and may be launched by a shortcut. | shell:startup opens your account’s folder; shell:common startup opens the all-users folder. |
| App-specific background settings | You want to reduce activity while an app is not in use, rather than prevent sign-in launch. | Some supported Store apps have a background-permissions setting; desktop apps require their own controls. |
What to expect after disabling startup apps
Microsoft notes that startup apps can slow boot time and increase background usage. Turning off an app you do not need at sign-in can reduce that app’s contribution, but Microsoft does not promise a fixed speed gain from disabling any one entry. The result depends on what the app does and the PC’s configuration, so use Task Manager’s rating to understand startup activity rather than treating it as a guaranteed time-saving estimate.
If an app you need stops appearing when you sign in, return to the same startup list and turn it back on. For a shortcut-based app, restore its shortcut to the appropriate Startup folder or use the app’s own startup setting, if it provides one.

When not to use a clean boot
A clean boot is intended to troubleshoot software conflicts, not to turn off one unwanted startup app. Microsoft’s instructions warn that misusing System Configuration can make a computer unusable and advise changing advanced boot options only with Microsoft support guidance. A clean boot can also temporarily remove functionality. For an ordinary startup cleanup, use the app’s toggle, Task Manager, or Startup-folder shortcut instead.
