Why your startup programs matter
Every program that opens when your computer starts uses memory and processing power before you even open a file. If you have ten programs launching automatically, your computer spends the first few minutes loading them instead of being ready for you to work. Changing which programs start up is one of the fastest ways to improve boot time and overall responsiveness.
Most programs add themselves to startup without asking. Web browsers, messaging apps, cloud storage services, and antivirus software all want to be ready the moment you log in. Some of these are worth having there. Others you never use until you manually open them, and they are just slowing you down.
Key Takeaways
- Windows and Mac both let you see and disable startup programs through built-in settings — you do not need special software to do this.
- Antivirus, cloud backup, and programs you use every day are usually worth keeping at startup; games, messaging apps you check occasionally, and media players usually are not.
- Disabling a startup program does not uninstall it — you can still open it manually whenever you want.
- If you disable something and your computer stops working the way you expect, you can turn it back on in the same place.
How to change startup programs on Windows 10 and 11
Open the Task Manager by pressing Ctrl + Shift + Esc on your keyboard. Click the Startup tab at the top. You will see a list of every program set to launch when Windows starts, along with its impact rating — High, Medium, or Low — based on how much it slows your boot.
Right-click any program you do not want starting automatically and select Disable. The program will no longer launch at startup, but it will still be installed on your computer. You can open it manually whenever you need it, or re-enable it later by right-clicking and selecting Enable.
Start with the programs marked High impact. Disabling even one or two of those will make a noticeable difference. Common culprits are Spotify, Discord, Slack, OneDrive, and Adobe Creative Cloud components. If you use these programs daily, keeping them at startup saves you a few seconds of opening time. If you use them a few times a week, disabling them is usually the better choice.
How to change startup programs on Mac
Click the Apple menu in the top-left corner and select System Settings (or System Preferences on older versions). Go to General, then click Login Items. You will see two sections: Open at Login and Allow in the Login Window.
The Open at Login section shows programs that launch automatically. Click any program in that list and click the minus button (–) below it to remove it from startup. Like Windows, this does not uninstall the program — it just stops it from launching automatically.
If you have an older Mac running Big Sur or earlier, the path is slightly different: go to System Preferences > General > Login Items, and you will see the same list. The process is identical.
Which programs are safe to disable
Programs you use every single day — email, your web browser, your work software — are worth keeping at startup if they take only a few seconds to load. Programs you open once or twice a week should usually be disabled. The difference between opening Photoshop manually when you need it versus having it load invisibly at startup is usually just a few seconds, and those seconds add up across your whole startup sequence.
Cloud storage services like OneDrive, Google Drive, or Dropbox are worth keeping at startup if you rely on them to sync files throughout the day. If you only check them occasionally, disable them. Antivirus software should almost always stay enabled — it needs to be running to protect you. Messaging apps like Slack, Discord, or Teams are personal preference: if you need to be reachable when ready, keep them; if you check them on your own schedule, disable them.
Never disable something just because you do not recognize the name. If you are unsure what a program does, search its name online before disabling it. Some programs have names that do not match their function, and some are part of Windows or Mac itself.
What to do if you disable something important
If you disable a startup program and your computer stops working the way you expect — your files are not syncing, your antivirus is not running, or something else breaks — you can turn it back on when ready. Open Task Manager or Login Items again and re-enable the program. The change takes effect the next time you restart.
If you are not sure whether something is important, disable it and restart your computer. Use your computer normally for a day or two. If nothing goes wrong, you made the right choice. If something stops working, you will know right away, and you can re-enable it.
How much faster will your computer be
The speed improvement depends on what you disable. Disabling one or two high-impact programs might cut your boot time by 10 to 30 seconds. Disabling five or six programs might cut it by a minute or more. The real benefit is not just boot time — it is that your computer is more responsive while you are working, because those programs are not running in the background using memory.
If your computer is still slow after disabling startup programs, the problem is usually something else: a full hard drive, malware, a failing hard drive, or hardware that is straightforward old. Startup programs are one piece of the puzzle, not the whole answer.
Frequently Asked Questions
Will disabling a startup program uninstall it?
No. Disabling a startup program only stops it from launching automatically when you log in. The program stays installed on your computer, and you can still open it manually whenever you want. You can also re-enable it at any time through the same settings.
Is it safe to disable programs I do not recognize?
Search the program name online before disabling it. Some programs have names that do not match what they do, and some are part of Windows or Mac itself. If you cannot find information about it, disable it and restart your computer. If nothing breaks in the next day or two, it was safe to disable.
Why does my computer still feel slow after I disabled startup programs?
Startup programs are one reason a computer feels slow, but not the only one. A full hard drive, malware, too many browser tabs, or old hardware can all cause slowness. If disabling startup programs did not help much, the problem is likely something else that needs a different fix.
Do I need to restart my computer for the changes to take effect?
Yes. Changes to startup programs take effect the next time you restart your computer. You do not need to restart when ready — you can make the changes and restart whenever you normally would.
