If you've already trimmed your startup apps in Task Manager but your PC still takes an age to feel usable after login, there's a good chance something is starting outside the places Task Manager even looks. Windows loads things from scheduled tasks, browser extensions, services, context menu add-ons, and several other hiding spots that never appear in the Startup tab. Autoruns, a free tool from Microsoft's own Sysinternals suite, shows you every single one of them in a single window.
Key takeaway: Autoruns exposes hidden startup items that Task Manager can't see, giving you full control over what actually loads when Windows boots.
Autoruns isn't dangerous to use, but it is powerful, which means it will happily let you disable something important if you're not careful. The good news is that unticking an entry doesn't delete anything, so almost every change you make can be reversed in seconds.
Before you start: Create a System Restore point before making changes (search "Create a restore point" in the Start menu), and only disable entries you recognise or have researched. If in doubt, leave it ticked.
Downloading and running Autoruns
Autoruns is published by Microsoft, so it's completely free and safe to download directly from the official Sysinternals site (part of learn.microsoft.com). There's nothing to install; it's a single executable you run directly.
- Download Autoruns (or the full Sysinternals Suite) from the official Microsoft Sysinternals page.
- Extract the downloaded zip file and double-click Autoruns64.exe (or Autoruns.exe on very old 32-bit systems).
- If prompted by User Account Control, click Yes — Autoruns needs administrator rights to see everything.
- On first launch, go to Options and tick "Hide Microsoft Entries" — this removes hundreds of legitimate Windows system entries and leaves you looking mainly at third-party software.
- Press F5 to refresh the scan with this filter applied.
Reading the tabs
Across the top of Autoruns you'll see tabs including Logon, Explorer, Scheduled Tasks, Services, and several more. The Logon tab is the closest equivalent to Task Manager's Startup list, but the Scheduled Tasks and Services tabs are where you'll often find the real culprits — background helper processes for printers, cloud storage apps, and creative software that quietly relaunch themselves even after you've disabled them elsewhere.
Disabling an entry safely
- Find the entry you want to stop, and check the "Publisher" and "Image Path" columns to confirm what it actually is.
- Right-click the entry and choose "Search Online" if the name is unfamiliar — this opens a quick web search so you can check what it does before touching it.
- Untick the checkbox next to the entry to disable it without deleting it.
- Restart your PC and confirm everything still works as expected.
- If something breaks, reopen Autoruns and simply re-tick the box to restore it instantly.
Tip: Sort any tab by clicking the "Timestamp" column header to see which entries were added most recently — handy for spotting something a new app install just planted without asking.
What's usually safe to disable
Update checkers for software you rarely use, "quick launch" helpers for printers and webcams that just preload the app faster, and duplicate cloud-sync agents are common safe targets. Leave anything related to your graphics drivers, audio drivers, antivirus, or Windows itself alone unless you specifically know what it does.
Comparing Autoruns to Task Manager
It's worth understanding why Task Manager misses so much in the first place. Task Manager's Startup tab only reads from a small handful of registry keys and one specific startup folder — the places Microsoft designed for simple, well-behaved apps to register themselves. Autoruns, by contrast, checks dozens of additional locations: browser helper objects, Explorer shell extensions, printer monitor drivers, Winlogon notification handlers, codecs, and more. This is exactly why a piece of software can keep relaunching itself even after you've disabled it in Task Manager — it's actually starting from one of these other locations entirely.
This also explains why IT professionals reach for Autoruns first when diagnosing a PC that "just feels slow for no reason." A single stray entry buried in the Winlogon or Explorer tabs can trigger several seconds of extra disk activity on every boot, long before the desktop even appears, which is activity Task Manager simply has no visibility into at all.
Keeping a record of what you change
Because Autoruns touches so many different areas of Windows, it helps to keep a simple note of exactly what you disabled and when, especially if you're working through a long list in one sitting. A quick text file with the entry name and date is usually enough — if something unrelated starts behaving oddly a week later, you'll have a starting point for narrowing down the cause rather than guessing.
Frequently asked questions
- Is Autoruns safe to download?
- Yes. It's published directly by Microsoft as part of the Sysinternals suite, the same team behind tools like Process Explorer, so there's no risk of malware bundled in.
- Will disabling an entry uninstall the program?
- No. Unticking a box in Autoruns only stops that item from launching automatically; the program itself remains installed and can still be opened manually.
- What if I disable something and Windows won't boot properly?
- This is extremely rare because Autoruns only manages auto-launch entries, not core system files. If it happens, boot into Safe Mode and use System Restore to roll back to the point you created earlier.
