If your laptop takes ages to become usable after switching on — icons appearing one by one, everything sluggish for the first five minutes — the usual culprit is not Windows itself but the crowd of apps that launch with it. Spotify, Adobe updaters, game launchers, meeting apps and manufacturer extras all quietly add themselves to startup. Disabling the ones you do not need at boot is the single fastest free speed-up for most PCs, and it deletes nothing.
1. Open the Startup list in Task Manager
Right-click the taskbar (or press Ctrl + Shift + Esc) and open Task Manager. Click Startup apps in the left sidebar (in Windows 10 it is the Startup tab at the top). You now see every program that starts with Windows, its publisher, and — the useful column — Startup impact: High, Medium or Low, Microsoft's own estimate of how much each one slows your boot.
2. Disable the obvious passengers
Right-click an entry and choose Disable. Safe, high-value targets on most home PCs: Spotify, Discord, Zoom and Teams (they open fine manually when needed), Adobe Acrobat/Creative Cloud updaters, Microsoft Edge pre-launch entries, game launchers like Steam and Epic if you do not game daily, OneDrive if you do not use it (see the warning below), printer "status monitor" helpers, and manufacturer promotional apps. Work top-down by High impact first — three or four High entries are often the entire problem.
3. What to leave enabled
Keep your antivirus/security software (Windows Security entries and any third-party antivirus), your audio and graphics helpers (for example Realtek audio), laptop touchpad/keyboard utilities from the manufacturer, and anything you genuinely use the second the PC starts. If you do not recognise an entry, search its name before disabling — most are harmless updaters, but a few are drivers in disguise. When in doubt, leave it enabled; this is a clean-up, not a purge.
4. The second startup list most people miss (Settings)
Windows 11 also keeps a friendlier list at Settings → Apps → Startup, with simple on/off toggles and the same impact ratings. It controls the same programs as Task Manager — use whichever you find clearer, not both. Also check the old-fashioned startup folder: press Windows key + R, type shell:startup, and Enter. Any shortcut sitting in that folder launches at sign-in; deleting the shortcut only removes the auto-launch, not the program itself.
5. Restart and measure honestly
Restart the PC (a real Restart, not Shut down — with Fast Startup enabled, Shut down does not fully test startup behaviour). Time how long until the desktop is responsive and compare with before. If a program you disabled turns out to be needed at boot after all, re-enable it in the same Task Manager list — every change here is reversible in seconds, which is exactly why this is the safest speed fix to try first.
6. Still slow after startup is clean?
Then the bottleneck is elsewhere: a nearly full system drive, a failing old hard disk, too little RAM for your workload, or Windows updates installing in the background. Work through our full slow Windows laptop guide next, and check your drive health with the Windows hardware reports if the laptop is several years old. Startup clean-up plus those checks cover the great majority of "my PC has become slow" cases without spending a rupee.
Frequently asked questions
Will disabling a startup app break or uninstall the program?
No. The program stays fully installed and opens normally whenever you click it. Disabling only stops it from launching automatically when Windows starts.
Why is my PC still slow for a minute after the desktop appears?
Windows itself finishes loading services, search indexing and sometimes updates just after sign-in. If the delay is several minutes rather than one, combine this clean-up with the checks in our slow-laptop guide — a full or failing drive is the usual next cause.
Is it safe to disable everything in the Startup list?
No — keep security software and hardware helpers (audio, graphics, touchpad) enabled. Disable the apps you recognise and do not need at boot; anything unfamiliar should be looked up first.
