Where startup programs live and why you should remove them
Startup programs are applications that launch automatically when you turn on your computer. Every program you install can request permission to start this way, and many do — even if you rarely use them. The more programs set to start automatically, the longer your computer takes to boot and the slower it runs while you are working.
You can see which programs are set to start and turn off the ones you do not need. This is one of the fastest ways to speed up a slow computer, because you are removing work your system has to do before you can use it. The process is different depending on whether you use Windows or Mac, but both let you control this directly without uninstalling anything.
Key Takeaways
- Windows users can open Task Manager, click the Startup tab, and disable programs by right-clicking and selecting Disable.
- Mac users can go to System Settings, select General, then Login Items, and remove programs from the list.
- Disabling a startup program does not uninstall it — the program still works normally when you open it manually.
- Most programs that start automatically are safe to disable, but cloud storage services and antivirus software should usually stay enabled.
- After you disable startup programs, restart your computer to see the difference in boot time.
Disable startup programs on Windows using Task Manager
Open Task Manager by pressing Ctrl + Shift + Esc on your keyboard, or right-click the taskbar at the bottom of your screen and select Task Manager. If Task Manager opens to a small window showing only running programs, click Details at the bottom left to see the full version.
Click the Startup tab at the top of the window. You will see a list of all programs set to start when Windows boots, along with their status (Enabled or Disabled) and the impact each one has on startup time. Programs marked High Impact slow down your boot the most.
Right-click any program you want to stop starting automatically and select Disable. The status will change to Disabled immediately. You do not need to restart right away — the change takes effect the next time you turn on your computer. If you disable something and later realize you need it to start automatically, you can right-click it again and select Enable.
Focus on programs you recognize and do not use regularly. Cloud storage services like OneDrive, Dropbox, or Google Drive are often worth keeping enabled if you use them daily. Antivirus software should stay enabled. Most other programs — messaging apps, media players, printer utilities — are safe to disable.
Disable startup programs on Mac using System Settings
Click the Apple menu in the top left corner and select System Settings. On older Macs running Monterey or earlier, this is called System Preferences instead. Look for General in the sidebar on the left, then click Login Items.
You will see two sections: Allow in the Login Items section and Allow in the Finder Sidebar. The Login Items section is what controls startup programs. Select any program in that list and click the minus button below it to remove it. The program will no longer start when you log in.
If you do not see a program you want to remove, scroll down to see if there is a section called Allow in the Finder Sidebar — programs there do not start automatically, they just appear in your sidebar. Only programs in the Login Items section need to be removed to speed up startup.
Understand what happens when you disable a startup program
Disabling a startup program does not uninstall it or change how it works. The program is still on your computer and still works exactly the same way when you open it manually. You are only telling your computer to stop launching it automatically in the background.
Some programs will ask to be re-enabled the next time you open them. This is normal — you can choose to re-enable it or keep declining. If you find you miss having a program start automatically, you can always turn it back on using the same steps you used to disable it.
Programs you should usually leave enabled
Antivirus and security software should stay enabled so your computer is protected from the moment it starts. If you use cloud storage — OneDrive on Windows, iCloud Drive on Mac, or Dropbox on either — keeping these enabled means your files stay synced without you having to think about it.
Graphics drivers and chipset drivers sometimes appear in the startup list. These are safe to leave alone; they do not slow down startup noticeably and some programs depend on them running in the background. If you are unsure whether something is a driver, search for its name online — the program name usually makes it clear what it does.
Printer utilities and scanner software can usually be disabled unless you use them every day. They will still work when you need to print or scan; you just will not have them running in the background all the time.
Restart your computer to see the difference
After you disable startup programs, restart your computer to see how much faster it boots. The difference is often noticeable, especially if you disabled several programs marked as High Impact. Your computer will also run more smoothly while you are working because fewer programs are competing for your attention and memory.
If your computer still feels slow after disabling startup programs, the issue may be something else — a full hard drive, too many browser tabs, or a program using a lot of memory while you work. But removing unnecessary startup programs is always a good first step and costs nothing to try.
What to do if you disabled something and your computer will not start properly
If you disabled a program and your computer no longer works the way it should, you can re-enable it. Open Task Manager or System Settings the same way you did before, find the program in the startup list, and turn it back on. Restart your computer and the problem should go away.
If you cannot remember which program you disabled, or if your computer will not start at all, restart in Safe Mode. On Windows, hold Shift while clicking Restart from the Start menu. On Mac, restart and hold Shift immediately after you hear the startup sound. Safe Mode loads only essential programs and lets you undo changes.
Frequently Asked Questions
Will disabling startup programs break anything?
No. Disabling a startup program only stops it from launching automatically — it does not uninstall it or change how it works when you open it manually. If something goes wrong, you can re-enable it in the same place you disabled it.
How many startup programs should I disable?
Disable any program you do not use regularly or do not recognize. Most people can safely disable 5 to 10 programs without any problems. Start with programs marked High Impact in Task Manager, as these slow down your boot the most.
Should I disable Windows Update or antivirus software?
No. Leave Windows Update and antivirus software enabled. These protect your computer and run in the background for a reason. Disabling them leaves your computer vulnerable to security problems.
Why is my computer still slow after disabling startup programs?
Startup programs are only one reason a computer slows down. If disabling them did not help much, the issue may be a full hard drive, too many browser tabs, or a program using a lot of memory while you work. Try restarting your computer first, then check how much free space you have on your hard drive.
Can I disable startup programs without using Task Manager or System Settings?
On Windows, some programs let you disable startup behavior from their own settings menu. Open the program, look for Preferences or Settings, and search for a Startup or Launch option. But Task Manager is the most reliable way to see and control everything in one place.
