What startup programs are and why they slow your computer down
When you turn on your computer, dozens of programs may launch automatically before you even open anything. These are startup programs — software that runs in the background from the moment your system boots up. Each one uses memory and processing power, even if you never see it on your screen.
Many of these programs are useful: your antivirus software, your keyboard driver, your network adapter. But others are not. Software companies often set their programs to start automatically so they load faster when you use them, or so they can check for updates and send you notifications. If you have ten or fifteen of these running at once, your computer will feel sluggish for the first few minutes after startup, and your hard drive will work harder than it needs to.
Disabling the ones you do not use regularly is one of the fastest ways to speed up your startup time and free up memory for the programs you actually want to run.
Key Takeaways
- You can see which programs start automatically by opening Task Manager on Windows or Activity Monitor on Mac, then looking at the Startup or Login Items tab.
- Disabling a startup program does not uninstall it — it just stops it from running when you boot up, and you can turn it back on anytime.
- Safe programs to disable include web browsers, messaging apps, cloud storage syncing tools, and software you rarely use.
- Keep antivirus software, security updates, and hardware drivers running at startup, since these protect your computer and keep it functioning properly.
How to disable startup programs on Windows
On Windows 10 and Windows 11, the easiest way to manage startup programs is through Task Manager. Right-click on your taskbar at the bottom of the screen and select "Task Manager" from the menu. If you do not see this option, press Ctrl + Shift + Esc to open Task Manager directly.
Once Task Manager opens, look for a tab labeled "Startup" at the top. Click it. You will see a list of all programs set to run when your computer starts. Each one shows a name, publisher, and a status column that says either "Enabled" or "Disabled." The "Impact" column on the right tells you whether that program uses high, medium, or low resources during startup.
To disable a program, click on it once to select it, then click the "Disable" button at the bottom right of the window. The status will change to "Disabled," and that program will no longer run when you restart your computer. You can disable multiple programs at once by holding Ctrl and clicking each one, then clicking Disable.
If you change your mind later, you can re-enable any program the same way: select it and click "Enable." Disabling a startup program does not uninstall it or prevent you from running it manually whenever you want.
How to disable startup programs on Mac
On Mac, startup programs are called "Login Items." Open System Settings (or System Preferences on older versions) and look for "General" in the sidebar. Click it, then find "Login Items" near the bottom of the window.
You will see two sections: "Open at Login" and "Allow in the Login Window." The "Open at Login" section shows programs that start automatically when you log in. To remove one, click it once to select it, then click the minus sign (−) button below the list.
Some programs may also appear under "Allow in the Login Window." These are usually security or system tools. You can remove these the same way if you want, but be cautious — removing security software or system utilities can cause problems. If you are not sure what a program does, leave it alone or search for its name online first.
Which startup programs are safe to disable
The safest programs to disable are ones you recognize and do not use regularly. Web browsers like Chrome, Firefox, or Edge often set themselves to start automatically — you can safely disable these since you can open them manually whenever you need them. The same goes for messaging apps like Slack or Discord, cloud storage tools like Dropbox or OneDrive (though see the note below), and media players or office software you do not use every day.
Adobe Reader, Spotify, Steam, and similar consumer software are almost always safe to disable. These programs want to start automatically so they load faster when you use them, but you lose nothing by turning off that feature.
One exception: if you use OneDrive, Google Drive, or another cloud storage service to sync files, disabling it from startup means your files will not sync until you manually open the program. If you rely on those files being current, you may want to leave it enabled. You can always disable it later if you find it slows your startup too much.
Which startup programs you should never disable
Leave these running at startup: your antivirus or security software, Windows Defender (on Windows), any security update services, and hardware drivers for your keyboard, mouse, network adapter, or graphics card. These programs protect your computer or make your hardware work correctly. Disabling them can expose you to malware, prevent you from connecting to the internet, or cause your display to look wrong.
If you see a program in your startup list and do not recognize the name, do a web search for it before disabling it. Many system tools have names that do not when ready tell you what they do. If you cannot find information about it, err on the side of caution and leave it enabled — you can always try disabling it later if you want to experiment.
What to do if disabling a program causes problems
If you disable a startup program and then notice something stops working — your printer does not print, your network does not connect, your display looks wrong — you know the disabled program was important. Go back to Task Manager or Login Items and re-enable it. The problem should go away after you restart your computer.
If you are not sure which program you disabled, you can re-enable all of them and then disable them one at a time to find the culprit. This takes longer but is safer than guessing. Keep notes of which ones you disable so you can track what you have changed.
How much faster will your computer be
The speed improvement depends on how many programs you disable and how much memory they use. If you disable five or six heavy programs, you might notice your startup time drops by 30 to 60 seconds and your computer feels more responsive for the first few minutes after boot. If you only disable two or three lightweight programs, the change may be barely noticeable.
The best approach is to disable the programs with "High" impact first — Task Manager shows you which ones these are. Then restart your computer and see how it feels. If you want more speed, disable a few more and test again. You can always turn them back on if you miss the features they provided.
Frequently Asked Questions
Will disabling a startup program uninstall it?
No. Disabling a startup program only stops it from running automatically when your computer boots. The program stays installed on your computer, and you can still open it manually anytime you want. You can also re-enable it in Task Manager or Login Items whenever you choose.
Can I disable startup programs on my work computer?
It depends on your company's policies. Some work computers are locked down so you cannot change startup settings. If you try to disable a program and nothing happens, or if you see a message saying you do not have permission, contact your IT department before trying again. They may have disabled that feature intentionally.
What if I see a startup program I do not recognize?
Search for the program name online along with the word "startup" — for example, "svchost startup Windows." Many system tools have unfamiliar names. If you cannot find clear information about what it does, leave it enabled. You can always try disabling it later if you want to test whether your computer still works without it.
Should I disable cloud storage apps like OneDrive or Google Drive?
Only if you do not need your files to sync automatically. If you disable them, your files will not update until you manually open the app. If you rely on having current versions of your files available, keep them enabled. If you rarely use cloud storage, disabling it can free up memory and speed up startup.
How often should I review my startup programs?
Check your startup list every few months, especially after installing new software. Many programs add themselves to startup without asking. If you notice your computer has slowed down again, open Task Manager or Login Items and disable any new programs you do not recognize or do not use regularly.
