Start with Settings → Apps → Startup or Task Manager → Startup apps. Turn off one optional app at a time, restart, and check whether your normal work is ready sooner. Keep anything you rely on at sign-in enabled until you understand what disabling it does.

Measure the delay you actually notice

Before changing anything, separate the time before the sign-in screen appears from the delay after you enter your password or PIN. Startup app settings are most useful for work that begins around sign-in. If the desktop appears quickly but the cursor stutters while several programs open, this guide addresses the right part of the process. If the manufacturer logo stays on screen for minutes, record that separately. A startup toggle is unlikely to explain everything that happens before Windows reaches sign-in.

Define a repeatable finish point. You might stop the timer when your browser opens a blank tab and File Explorer responds, rather than when the wallpaper becomes visible. Use Restart for each comparison, with the same account and similar accessories connected. Note whether Windows Update is installing anything and wait for that work to finish before timing again. Take two or three measurements. If one restart takes substantially longer than the others, treat it as a clue to investigate instead of the baseline for your next change.

Read the Startup apps list

Open Settings, choose Apps, and select Startup. Look for the applications Windows recognizes as startup entries. The switch controls whether that entry starts automatically. Microsoft explains the distinction between Settings and Task Manager in its startup application guide. In Task Manager, open Startup apps to see a more detailed list, including the startup impact Windows has measured for entries where data is available.

Use impact as a starting point. An app that does important work can be worth the delay, while several small optional apps might together make sign-in feel busy. A high impact rating also does not tell you exactly how many seconds you will recover. Some programs run concurrently and share CPU or disk resources. Look at the app name, publisher, and purpose. If you recognize the name but do not know why it runs, check the application’s preferences and documentation before turning it off.

Disable an optional app and check the side effects

Choose an app you can comfortably launch yourself, such as a game launcher or a chat client you only use on demand. Turn its switch off in Settings or use Disable in Task Manager. This changes its startup entry. It does not uninstall the app or immediately close an instance that is already running. Restart, then check both startup time and the application itself. Open it manually and verify that its ordinary functions still work.

Be more cautious with cloud sync, input utilities, accessibility tools, backup clients, security software, and managed device agents. Some features may depend on a background component being ready as soon as you sign in. A sync client, for example, might stop updating local copies until you start it. Before changing a tool that maintains a second copy of your files, use our backup testing guide to verify what you can recover. If a computer belongs to work or school, follow the organization’s guidance for its managed tools.

Check apps that still open on their own

An app can expose a launch-at-login switch in its own preferences. If an entry turns itself back on after an update or opens even when the Startup list says it is disabled, look there first. Windows can also reopen some restartable apps after you sign back in, depending on your sign-in settings. For a comparison, close the app before restarting and see whether it still opens. That helps distinguish an ordinary startup entry from a restored session.

Windows also supports Startup folders. Microsoft’s guide documents shell:startup for the current user and shell:common startup for shortcuts that apply to users on the device. You can enter the relevant command in Run and inspect the shortcuts. Confirm the target of any shortcut you do not recognize. If you are testing your own shortcut, moving it temporarily to a safe folder gives you a simple way to put it back. On a shared PC, remember that the common folder can affect other people’s sessions.

Measure again and isolate other bottlenecks

Run the same test you recorded before. Notice whether the machine becomes usable sooner and whether a needed service still starts. Keep a short log with the changed entry and the result. If nothing improves, turn that entry back on when you use it regularly. If you saw a clear improvement, repeat the test after a normal day of work so you know that the change fits your actual routine.

If Task Manager shows persistent disk activity after the initial sign-in, check which process is responsible. A nearly full Windows drive may need a separate cleanup and space check. Our Storage Sense guide explains how to review space without automatically removing Downloads. If a laptop only seems slow while unplugged, check its Windows power mode and workload before treating it as a startup issue. The battery report guide can help distinguish battery capacity from behavior under load. Treat those as separate measurements so you can tell which change helped.

Keep the settings useful after updates

Review the list after installing a suite that includes several companion tools. An updater, sync component and launcher can each have a separate role. Open the application first and see which features you use. Then decide whether any of them need to be ready at sign-in. If you use the same app only occasionally, keep a convenient shortcut for manual launch and note which feature will wait until it is open.

For shared computers, test the account that had the problem. An entry may apply only to one user, and the symptoms can be different on another account. Write down any change you make to a shared startup location. This gives you a straightforward rollback if a printer utility, keyboard feature, or scheduled activity later appears to have stopped working. Recheck the settings after major app upgrades if the same delay comes back.

If your usual complaint is that a browser takes too long to open, repeat the test with the same browser profile and the same first page. Loading a remote page can introduce a network delay that has nothing to do with startup. An empty tab or a local document gives you a cleaner timing comparison. Then repeat with your normal workflow to see whether the difference matters in practice.

Frequently asked questions

Can I turn an app back on?

Yes. Enable the startup entry again in Settings or Task Manager, then restart to check that it launches as expected.

Why is the startup impact blank?

Windows may not have measured that entry yet. Judge it using a repeatable sign-in test and the app’s role in your workflow.

Does disabling a launcher stop updates?

That depends on the application. Check whether its updater is separate and confirm that manual launch still checks for updates if you depend on it.
