How to Check Startup Apps on a New Computer
A new computer should feel fast, but startup apps can quietly slow the first boot and consume memory before you even open a browser.
Knowing how to check startup apps on new computer setups helps you spot unnecessary software, keep essential tools running, and start with better performance.
What startup apps are and why they matter
Startup apps are programs that launch automatically when Windows, macOS, or another operating system begins loading.
Common examples include cloud storage sync tools, communication apps, gaming launchers, audio utilities, printer software, and security tools.
Some startup items are useful because they provide instant access to important features.
Others are simply preinstalled software, vendor utilities, or apps that added themselves during installation and now run in the background every time you sign in.
- Faster boot times: fewer apps loading at sign-in means a quicker desktop.
- Lower memory use: fewer background processes leave more resources for active work.
- Improved battery life: laptops often benefit from reduced background activity.
- Better system clarity: you can see which apps actually deserve to start automatically.
How to check startup apps on Windows 11 and Windows 10
Windows makes it straightforward to review startup entries.
On most modern PCs, the main control point is Task Manager, where you can see which apps are enabled, disabled, and how much impact they have on boot time.
Use Task Manager to review startup programs
- Right-click the taskbar and choose Task Manager, or press Ctrl + Shift + Esc.
- If needed, select More details.
- Open the Startup apps tab.
- Review each entry, including Status and Startup impact.
- Right-click a nonessential app and choose Disable to stop it from launching automatically.
Windows 11 also shows startup settings in Settings > Apps > Startup.
This view is useful because it gives a simpler on-off control list for beginners.
What to keep enabled on a Windows PC
Not every startup app should be disabled.
Security software, audio drivers, touchpad utilities, and hardware support tools often belong there.
If you use OneDrive, Dropbox, Adobe Creative Cloud, or similar services for automatic file syncing, you may want them to remain active.
- Keep: antivirus and endpoint protection, hardware drivers, keyboard or touchpad utilities, cloud sync tools you rely on.
- Review carefully: update checkers, printer helpers, chat apps, gaming clients, vendor launchers.
- Usually disable: trial software, duplicate launchers, rarely used utilities, promotional updaters.
How to check startup apps on a Mac
On macOS, startup items are managed through Login Items and background processes.
Apple separates items you open at login from helper processes that may run in the background, so both views are worth checking on a new Mac.
Check Login Items in macOS
- Open System Settings.
- Go to General and then Login Items.
- Review the list under Open at Login.
- Select an item and click the minus button to remove it if you do not want it to launch automatically.
In the same area, macOS may show Allow in the Background.
These items can start services without opening a visible app window.
Review them carefully, especially after installing productivity suites, cloud storage tools, or device software.
What to keep on macOS
Some startup items are part of normal Mac usage. iCloud Drive, backup tools, menu bar utilities, and security software may be reasonable to keep.
If you connect peripherals such as external drives, USB docks, or audio interfaces, vendor support tools may also be needed.
- Keep: iCloud sync, backup tools, security software, device drivers, essential menu bar utilities.
- Review: app updaters, collaboration tools, game launchers, helper services.
- Disable if unnecessary: software you only use occasionally and do not need at every login.
How to check startup apps on other devices and operating systems
Although Windows and macOS are the most common desktop systems, the same idea applies elsewhere.
The goal is always to identify what launches automatically and decide whether it earns a place there.
Linux desktop environments
On Linux, startup apps are usually managed through a session and startup settings panel in the desktop environment.
GNOME, KDE Plasma, and other environments provide tools for disabling unwanted autostart entries.
If you installed software from a package manager, app launcher, or vendor installer, check for background services and desktop autostart files.
Chromebooks and mobile devices
Chromebooks have fewer traditional startup apps because ChromeOS is more controlled.
Mobile devices use different startup behavior, but the same principle applies: review installed apps, background permissions, and sync settings so the device stays responsive.
How to decide which startup apps are safe to disable
When you are learning how to check startup apps on new computer hardware, the hard part is not finding the list; it is deciding what to turn off.
Use the app’s purpose, vendor, and frequency of use as your guide.
Ask these questions before disabling anything
- Do I need this app every time I sign in?
- Does it provide a core function, such as security, syncing, or hardware support?
- Can I launch it manually when needed instead?
- Is it from a trusted vendor such as Microsoft, Apple, Adobe, Google, or my device manufacturer?
- Does disabling it affect updates, backups, or peripherals?
If you are unsure, disable one app at a time and observe the computer for a day or two.
Startup changes are easy to reverse, and gradual testing prevents problems.
Use system resource clues to identify heavy startup items
Modern operating systems often label startup impact, but resource behavior can also reveal which apps are expensive.
A heavy launcher may use CPU, disk, or network resources immediately after login, even if you never open it.
- High CPU use: can make the desktop feel sluggish during boot.
- Frequent disk activity: often affects laptops and systems with many background sync tasks.
- Network activity: may indicate cloud sync, update checks, or telemetry.
- Memory use: reduces available RAM for browser tabs, games, and work apps.
On Windows, Task Manager can show startup impact and live process behavior.
On macOS, Activity Monitor helps you identify apps consuming CPU, memory, energy, or network resources after login.
Best practices for a new computer setup
A new PC or Mac is the best time to create a clean startup environment.
If you review startup apps early, you can avoid carrying over unnecessary clutter from day one.
- Install only the software you need.
- Check startup items immediately after setup.
- Disable duplicate launchers and unnecessary update helpers.
- Keep security, syncing, and device support tools if they serve a clear purpose.
- Recheck startup items after major software installations or updates.
It also helps to remove bloatware, turn off promotional trial software, and avoid installing multiple apps that do the same job.
For example, running several cloud sync clients, game launchers, or system optimizers can increase boot time without improving usability.
When startup items might indicate a problem
Sometimes a long startup list is not just inconvenient; it can signal bundled software, unwanted utilities, or even malware.
If you see unfamiliar names, misspelled vendors, or apps you did not install, investigate before disabling or deleting anything.
- Unknown publisher: verify the software source before making changes.
- Recently added entries: check after a new install if startup behavior changed.
- Repeated reappearance: some programs restore themselves after updates.
- Suspicious names: generic or random-looking labels deserve closer inspection.
If something looks unsafe, use trusted security tools, review installed applications, and confirm the file location or publisher before taking action.
Quick checklist for checking startup apps on a new computer
- Open the startup app list in Windows or macOS.
- Identify security, sync, driver, and utility apps.
- Disable trial software, launchers, and helpers you do not need.
- Test one change at a time.
- Revisit the list after installing new software.
