For most changes, use Settings > Apps > Startup: find an app and switch its toggle off to stop it opening automatically when you sign in. Use Task Manager > Startup apps when you also want to see Microsoft’s startup-impact measurement. Both interfaces enable or disable the same registered startup-app list; Task Manager adds diagnostic detail rather than a different set of controls.
Disabling an entry prevents automatic launch at sign-in, but it does not uninstall the program. If an app is not listed, Windows may be launching it from a Startup folder or another location that needs separate troubleshooting.

What “startup apps” means in Windows 11
A startup app is a program configured to launch when you sign in to Windows. This is separate from opening an app yourself later, and it is not the same as every background process or Windows service. The controls discussed here concern registered applications that run automatically at sign-in.

Microsoft recommends disabling startup apps you do not need to launch automatically, but it does not provide a universal number of seconds that every PC will save. The result depends on the app, storage, processor, and the rest of the system.
#1 Best Overall
Windows 11 gives you two built-in management views:
- Settings is the clearest place for routine on/off changes and may expose an app-specific advanced-settings chevron.
- Task Manager controls the same registered apps and adds startup-impact labels that help you investigate resource use.
Neither view can decide whether you personally need an app. A synchronization, security, accessibility, or communications tool might be important to you even if its measured impact is high, while a low-impact launcher may be unnecessary.
Settings versus Task Manager at a glance
| Question | Settings | Task Manager |
|---|---|---|
| Where is it? | Start > Settings > Apps > Startup | Right-click Start > Task Manager > Startup apps |
| What can you do? | Switch each listed app on or off | Select an app, then choose Enable or Disable |
| Which apps appear? | The registered startup-app list | The same registered startup-app list |
| Extra information | An advanced-settings chevron may appear for an app | Startup-impact information for each entry |
| Best use | Quick, low-risk routine changes | Comparing measured startup resource use while deciding what to investigate |
Microsoft describes Task Manager as providing “a more detailed view, including the impact each app has on the startup process.” That detail is useful context, not an instruction to disable every item with a high label.
How to turn startup apps off or on in Settings
Settings is the simplest workflow if you already know which app should or should not launch at sign-in.
- Open the Start menu.
- Select Settings.
- Choose Apps, then Startup.
- Find the app in the list. The entries are the startup applications Windows has registered for this view.
- Switch the app’s toggle Off to prevent automatic launch at your next sign-in, or switch it On to allow automatic launch.
- If a chevron appears beside the app, select it to view the advanced settings Windows makes available for that entry.
Turning a toggle off changes automatic startup behavior; it does not remove the application, its files, or your account data. You can return to the same page and switch it back on if you change your mind.
When Settings is the better choice
- You want a direct toggle without interpreting extra columns.
- You are making a single change and do not need to compare resource measurements.
- You want to check whether Windows exposes advanced settings for a particular app.
- You are helping another person and want the least ambiguous path to explain.
How to turn startup apps off or on in Task Manager
Task Manager is useful when startup performance is the reason you are making changes. Its Startup apps page uses the same registered-app list as Settings, so you are not managing a separate category of programs.
- Right-click the Start button.
- Select Task Manager.
- Open Startup apps. If Task Manager opens in a compact view, use its option to show the full interface first.
- Select the app you want to change.
- Choose Disable to stop it launching automatically, or Enable to permit launch at sign-in again.
Use the impact column to prioritize investigation, not as a universal keep-or-disable verdict. If you depend on an app’s sign-in notification, file synchronization, security protection, or other automatic function, disabling it may remove that behavior until you open the app or re-enable startup.

- You need the same enable/disable control but prefer a diagnostic view.
What Task Manager’s startup-impact labels mean
Task Manager’s impact value is a measurement of startup resource use. It describes what Windows measured for that startup activity; it does not describe whether the program is safe, essential, or personally useful. Microsoft’s definitions are:
| Label | Microsoft’s definition | How to use it |
|---|---|---|
| None | The startup app is disabled. | There is no current automatic launch to measure. |
| Not measured | The app is enabled, but measurement data is unavailable. | Do not treat the missing measurement as proof of low or high impact. |
| Low impact | Total CPU usage is under 300 milliseconds and total disk usage is under 292 kilobytes. | The measured startup activity is small under Microsoft’s thresholds; decide based on whether you need the app. |
| Medium impact | Total CPU usage is under 1 second but over 300 milliseconds, or total disk usage is under 3 megabytes but over 292 kilobytes. | Consider it a candidate for review if you are reducing startup work. |
| High impact | Total CPU usage is over 1 second or total disk usage is over 3 megabytes. | It may deserve investigation during performance troubleshooting, but the label alone is not a recommendation to disable it. |
These are Microsoft’s operational thresholds, not a promise that a particular label will produce a specific boot-time improvement on your computer. “Not measured” means enabled without available measurement data; it does not mean disabled.
A practical way to decide what to disable
Start with purpose, then use impact as supporting evidence. This avoids the common mistake of treating the impact column as a list of apps that Windows says are unnecessary.
- Identify the app. Read its name and, where available, inspect the advanced information or details associated with it. If you do not recognize an entry, do not disable it solely because the name looks unfamiliar.
- Ask whether automatic launch is needed. Consider whether you require the app to be ready immediately after sign-in, provide notifications, synchronize files, or perform another function without being opened manually.
- Check the impact in Task Manager if startup speed is the concern. A high or medium label tells you where Windows measured more startup resource use; it does not establish that the app is the cause of every delay.
- Change one or a small, clearly understood group at a time. This makes it easier to identify which change affected your workflow.
- Sign out or restart, then observe. Confirm that the app no longer launches automatically and that you have not lost a function you rely on.
- Re-enable when necessary. Return to Settings or Task Manager and restore the app’s startup setting if you need its automatic behavior.
What disabling does not do
- It does not uninstall the application.
- It does not delete the application’s shortcut, files, or settings.
- It does not necessarily stop a program that is launched by a service, scheduled task, browser extension, or another mechanism outside the registered startup-app list.
This guide focuses on automatic sign-in launches. Broad service changes belong to separate advanced troubleshooting procedures and can temporarily remove functionality.
What to do when an app is missing from both lists
Microsoft documents two Startup folders for programs that are configured through File Explorer rather than the registered startup-app list. A shortcut placed in one of these folders launches the target at sign-in; removing the shortcut stops that folder-based launch.
| Scope | Open this shortcut | Corresponding folder path |
|---|---|---|
| Only your Windows account | shell:startup |
%userprofile%AppDataRoamingMicrosoftWindowsStart MenuProgramsStartup |
| All users on the device | shell:common startup |
%ProgramData%MicrosoftWindowsStart MenuProgramsStartup |
Open the current-user Startup folder
- Press Windows key + R to open the Run dialog.
- Enter
shell:startup, then press Enter. - Review the shortcuts in the folder. Remove a shortcut only when you are certain which automatic launch it controls.
- To add an app, place a shortcut to its executable in this folder. The shortcut, rather than a duplicate copy of the program, is what Windows uses to launch it.
Open the all-users Startup folder
- Press Windows key + R.
- Enter
shell:common startup, then press Enter. - Review or manage shortcuts that apply to every user on the device, taking account of the permissions required to change that folder.
The shortcut method is preferable to editing the registry for ordinary troubleshooting because it is easier to inspect and undo. If a folder shortcut points to a program that has moved or been removed, deleting that obsolete shortcut stops the failed launch attempt.
Handling “We couldn’t find this app”
Windows can show “We couldn’t find this app” when a startup entry points to a location that no longer exists. Microsoft identifies several possible causes:
- The app is on a removable drive that is not currently connected.
- The app is on a network drive that is unavailable.
- The file path has changed or no longer exists.
- The application was uninstalled while its startup registration remained.
Selecting the details icon can reveal the file path or registry location associated with the broken entry. Use that information to determine whether the drive needs to be connected, the application needs to be repaired or reinstalled, or the obsolete startup entry should be removed.

Why registry edits require extra caution
Windows also has registry Run locations for startup programs for all users and for the current user. Registry changes can have unintended consequences. Microsoft advises backing up the registry before making changes, and registry troubleshooting is not the first step for a general startup-app problem.
Use Settings, Task Manager, or the documented Startup folders first. Consider registry work only when you understand the location involved, have a recovery plan, and are addressing a startup entry that those safer interfaces do not expose. Do not delete an unfamiliar value merely because it has a high impact or an unclear name.
Troubleshooting common outcomes
The app still opens after you disabled it
- Confirm that the toggle in Settings or the status in Task Manager actually shows the app as disabled.
- Sign out or restart so you are testing a fresh sign-in rather than an app that was already running.
- Check the two Startup folders for a separate shortcut.
- Consider whether another mechanism, such as a service or scheduled task, is launching it. Startup-app controls do not cover every background component.
A needed app no longer starts automatically
- Open Settings > Apps > Startup or Task Manager > Startup apps.
- Locate the app and switch it on or choose Enable.
- If it is not listed, inspect the appropriate Startup folder and restore its shortcut.
- Sign out and sign in again to verify the change.
The impact column says “Not measured”
The app is enabled, but Windows has no measurement data available. You can still enable or disable it. Decide based on whether you need its automatic behavior, and do not infer a performance rating from the absence of a measurement.
Startup feels slow even after disabling several entries
Do not assume that every delay comes from registered startup apps. Windows startup can also involve sign-in tasks, services, storage activity, updates, and hardware constraints. The documented impact labels can help prioritize registered apps, but they do not provide a guaranteed total boot-time reduction or explain every source of delay.
Recommended Free Tools
Safe checklist before and after a change
- Record the app name and its current enabled or disabled state.
- Decide whether you need its notifications, synchronization, protection, or other sign-in behavior.
- Use Settings for a straightforward toggle or Task Manager when impact information matters.
- Change only entries you recognize or can identify through their details.
- Restart or sign out to test the result.
- Re-enable the app if a required function disappears.
- Use Startup folders for unlisted folder-based entries.
- Back up the registry before any registry change, and avoid registry editing unless it is necessary and you understand the risk.
Which tool should you choose?
Choose Settings when your goal is simply to stop or allow an app at sign-in. Its path is easy to remember, and the toggle makes the result explicit.
Choose Task Manager when you are investigating startup performance or comparing several entries. It controls the same apps while showing measured impact categories, including the “Not measured” state. Treat those categories as evidence about resource use, not as a list of applications Windows has declared unnecessary.
If the app appears in neither list, move to the appropriate Startup folder. Use registry troubleshooting only as a cautious, informed last resort, and keep the scope on automatic sign-in launches rather than unrelated services or processes.
