Windows 11 Slow to Boot? Disable Startup Apps and Cut Your Sign-In Wait

You sign in to Windows 11, the desktop appears, but the machine is unusable for the next minute or two — the disk light is solid and everything is sluggish.

Why: Every app that’s set to launch at sign-in (chat clients, cloud sync, updaters, GPU tools, “helper” tray icons) fights for the CPU and disk at the same moment. Windows itself starts fast; it’s the pile of third-party startup programs that drags out the time until the PC is responsive. Microsoft notes these apps “can impact both the speed of your startup and the overall performance of your system.”

Fix 1: Disable high-impact apps in Task Manager (fastest)

Task Manager rates each startup item, so you can target the worst offenders first.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Select Startup apps from the left-hand menu.
3. Click the Startup impact column header to sort, or just look for items marked High.
4. Right-click an app you don’t need at boot and choose Disable.

What the ratings mean (Microsoft’s own thresholds):

• Low impact — uses less than 300 ms of CPU and under 292 KB of disk at startup.
• Medium impact — 300 ms to 1 second of CPU, or 292 KB to 3 MB of disk.
• High impact — more than 1 second of CPU or more than 3 MB of disk.

Safe to disable for almost everyone: Spotify, Steam, Epic Games Launcher, Discord, Adobe updaters, printer/GPU “assistant” tools, and chat apps. Leave alone anything you don’t recognize that’s published by Microsoft, plus your antivirus. Disabling only stops the app from auto-launching — you can still open it manually whenever you want.

Fix 2: Do the same from Settings

Settings shows the same list with simple on/off toggles, which some people find clearer.

1. Open Settings → Apps → Startup.
2. Turn the toggle Off for each app you don’t need at sign-in.
3. Select the chevron (the small arrow) next to an app for its advanced options.

Changes here and in Task Manager are the same list — flip them in whichever place you prefer.

Fix 3: Clean boot to find a hidden background hog

If startup is still slow after trimming the obvious apps, a background service may be the culprit. A clean boot temporarily disables every non-Microsoft service so you can confirm the cause.

1. Press Win + R, type msconfig, and press Enter to open System Configuration.
2. On the Services tab, tick Hide all Microsoft services, then click Disable all, then Apply.
3. On the Startup tab, click Open Task Manager and disable each enabled item there too.
4. Click OK and restart.

If boot is now fast, re-enable services in small batches (clear Hide all Microsoft services is off, enable a few, restart) until the slow one reappears. To return fully to normal: in System Configuration’s General tab pick Normal startup, re-enable services and startup items, and restart.

FAQ

Will disabling startup apps break anything? No. The programs still work — they just won’t launch automatically. Things like cloud sync (OneDrive, Dropbox) you may want to keep on; updaters and game launchers are safe to turn off.

Why does it say “Not measured” next to some apps? Windows hasn’t recorded that app’s startup impact yet. It usually fills in after a reboot or two.

My startup is still slow with nothing in the list. That points to disk or driver issues rather than apps — check disk health and free space, and make sure you’re on an SSD if the machine supports one.
