You press the power button, walk away to make tea, and come back to a computer that is somehow still busy. Half a dozen programs you never opened are sitting in the taskbar, each one quietly checking for updates, syncing files, or just waiting around. You didn’t ask for any of this. Your computer starts the day with a full schedule before you’ve even touched the keyboard.
That’s the startup queue: the list of apps your operating system launches automatically every time you sign in. Most of them got there without you making a conscious decision — a checkbox you skipped during installation, a default that switched itself on after an update, a program that assumed you wanted it around. The good news is the list is yours to edit, and trimming it is one of the simplest performance wins on a computer that feels sluggish out of the gate.
Why your computer is busy before you touch anything
Programs have perfectly good reasons for wanting to start with your computer. A chat app wants to catch your messages the moment you log in. Cloud storage wants to start syncing. A printer utility wants to be ready when you hit Print. Individually, each one is reasonable. Collectively, on a machine that’s been used for a year or two, they turn booting up into a long, competitive queue — and every entry in that queue is reading from your disk and using memory at exactly the moment your system is trying to get itself running.
The queue also grows silently. Many installers tuck in a “launch when my computer starts” option that is switched on by default. Updates sometimes re-enable an entry you previously switched off. So even if you trimmed the list once, it’s worth a fresh look every few months.
Seeing the full lineup on Windows
Windows gives you two views of the same list. The quickest is Task Manager: press Ctrl + Shift + Esc, then open Startup apps from the sidebar. You’ll see every program set to launch at sign-in, each with a status (Enabled or Disabled) and a Startup impact rating — High, Medium, or Low — which is the operating system’s own estimate of how much that app slows down booting. Sort by that column and the worst offenders float to the top.
The friendlier view lives in Settings: press Windows key + I, go to Apps > Startup, and you get the same list with simple on/off toggles and the same impact ratings. Either route does the same job; Settings is easier to read, Task Manager is faster.
To stop an app from launching automatically, flip its toggle or right-click it and choose Disable. That’s it — nothing is uninstalled, nothing is deleted. The app still works perfectly when you open it yourself; it just no longer gets a head start.
Deciding who stays and who goes
This is the part people worry about, so here’s the reassuring bit: disabling a startup entry cannot break your computer. The app itself is untouched — only its automatic launch is switched off. If you miss it, turning it back on is one click in the same place.
That said, a little judgment helps. Safe to switch off: chat and video-call apps you only open for meetings, game launchers, media players, cloud storage you use occasionally, printer utilities for a printer you rarely use, and anything from software you don’t remember installing. Leave alone: your security software, anything related to your graphics card, audio drivers, or fingerprint reader, and entries whose publisher is Microsoft or your computer’s manufacturer. Those tend to be doing something the system expects.
When in doubt, pick one app, switch it off, restart, and see. The worst-case scenario is discovering you wanted it — and the fix takes ten seconds. If you want to add something to the list instead — say, a note-taking app you genuinely open every day — press Windows key + R, type shell:startup, and drop a shortcut for the program into the folder that opens.
The same cleanup on a Mac
Macs keep two related lists. Open System Settings, go to General, then Login Items & Extensions. Under Open at Login you’ll see the apps that appear when you sign in — select one and click the – button to remove it. Below that, Allow in the Background lists the helper processes apps have registered: updaters, sync engines, menu-bar utilities. Toggle off the ones you don’t need.
One useful trick Apple keeps quiet: at the login window, hold Shift while you click Log In, and keep holding until the desktop appears. That skips everything on the login list for that session only — handy when something in the queue is misbehaving and you want to see if the list is the culprit. (On older Macs running macOS Monterey or earlier, the same list lives under System Preferences > Users & Groups > Login Items.)
A few quiet ways apps sneak back on
Sometimes you switch an app off and it returns a week later, and it’s worth knowing the three usual routes back in. First, many apps have their own “open at login” or “launch at startup” setting inside their preferences — the system-level switch and the app’s own switch can disagree, and the app’s own setting often wins on updates. Second, reinstalling or updating a program can restore its startup entry, so a quick glance at the list after big updates is a decent habit. Third, some utilities register background helpers rather than full apps, which is why the Mac’s “Allow in the Background” section and Windows’ background app permissions are worth a look too.
None of this is malicious. It’s software competing for your attention the same way it competes for everything else. But attention is yours to budget, and a computer that greets you with a clean desktop instead of a traffic jam is one of the cheaper upgrades you’ll ever make — it costs about five minutes and changes nothing you actually use.
