About Startup Cleaner -- Speed Up Your PC Boot Time
Scan and disable unnecessary startup programs to speed up your PC boot time. Generate a script to list or remove startup items on Windows, macOS, and Linux.
How to use
- Pick your operating system tab -- Windows, macOS, or Linux. Each OS stores startup programs in different places: Windows checks Registry Run keys, the Startup folder, and Scheduled Tasks; macOS uses Launch Agents (
~/Library/LaunchAgents) and Login Items; Linux uses systemd user services and XDG autostart files (~/.config/autostart). The generated script targets the right locations for your platform automatically.
- Start with Scan First mode -- it's selected by default and it's the safe choice. Scan First generates a read-only script that inventories every program configured to launch at boot, including hidden ones Task Manager won't show. Run this first to see what's actually loading on your machine. Many users discover 20-30 startup entries they didn't know existed.
- Once you know what's there, switch to Disable Selected mode and check the boxes for programs you want to stop launching at boot. Each item shows a
Safe to disable or Use caution badge plus a one-line description. Common safe targets: Spotify, Discord, Steam, Adobe Updater, Xbox Game Bar, manufacturer bloatware (HP/Dell/Lenovo utilities). Use Select All / Deselect All at the top to bulk-toggle.
- Leave the cautious items alone unless you know what they do. OneDrive, Dropbox, and Google Drive are flagged with
Use caution because disabling them stops live cloud sync -- fine if you only use them occasionally, but a problem if your work depends on synced files. Antivirus, audio drivers, and accessibility tools should stay enabled.
- Click Copy Script or Download Script. Important limitation: this tool runs entirely in your browser and cannot read your actual installed programs -- the list shows common startup culprits, not what's truly on your system. The Scan script reveals everything for real when you run it. For a complete view, also check Task Manager > Startup tab on Windows or System Settings > General > Login Items on macOS.
- Open an elevated terminal and run the script. On Windows: right-click Start > Terminal (Admin) or PowerShell (Admin) -- the script needs admin to modify Registry Run keys. On macOS: open Terminal from Applications > Utilities --
launchctl unload commands are user-scoped so no sudo needed. On Linux: open your terminal emulator -- systemctl --user disable handles your user services without root.
- Reboot to see the result. Startup changes only take effect on the next boot. A typical Windows machine with 20+ startup items dropping to 5-8 essentials shaves 30-60 seconds off login time, plus your computer feels responsive immediately instead of churning for the first few minutes. To re-enable later: on Windows, press
Ctrl+Shift+Esc > Startup tab > right-click > Enable. On macOS, System Settings > General > Login Items. On Linux, systemctl --user enable servicename.
Frequently asked questions
Will disabling startup programs break anything?
Disabling a startup program only prevents it from launching automatically when your computer boots -- it does not uninstall the program or delete any data. The program still works perfectly when you open it manually from the Start menu, Dock, or application launcher. For example, disabling Spotify from startup means it will not open automatically, but you can still launch it whenever you want to listen to music. The only exception is security software (antivirus, firewall) and system-critical services -- the tool flags these and recommends keeping them enabled. If you accidentally disable something important, you can re-enable it using the same method in reverse.
Can I scan before disabling anything?
Yes -- Scan First mode is specifically designed for this. It generates a read-only script that inventories all your startup programs and displays them in a clear list with their names, file paths, and startup type (Registry, Scheduled Task, Login Item, etc.). No changes are made to your system. This lets you see exactly what is launching at boot so you can make informed decisions about what to disable. Many users are surprised to discover 15-30 startup programs running on a typical Windows PC, many of which were silently added by software installers. Reviewing the scan results before making any changes is always the recommended approach.
How much faster will my PC boot?
The improvement depends on how many unnecessary programs are currently launching at startup and how resource-intensive they are. A typical Windows PC with 20+ startup items may take 60-90 seconds to become usable after login. Disabling 10-15 unnecessary items often reduces this to 20-30 seconds -- a noticeable improvement you will feel every time you turn on your computer. The biggest gains come from disabling programs that load heavy frameworks or perform network operations at boot (like cloud sync clients, auto-updaters, and manufacturer bloatware). Lightweight programs like notification area icons have minimal impact individually but add up when there are many of them.
What startup programs are safe to disable?
Most third-party software does not need to run at startup. Common safe-to-disable programs include: auto-updaters (Adobe, Java, Google, Spotify), cloud storage sync clients you rarely use (OneDrive, Dropbox, Google Drive -- unless you rely on them constantly), manufacturer bloatware (HP, Dell, Lenovo utilities), gaming launchers (Steam, Epic Games, Discord), and communication tools (Slack, Teams, Zoom -- unless you use them immediately after booting). Programs you should keep enabled include antivirus/security software, display/audio drivers, accessibility tools, and any VPN client you need connected at all times. When in doubt, search the program name online to learn what it does before disabling it.
How do I re-enable a program I disabled?
On Windows, the simplest method is Task Manager: press Ctrl+Shift+Esc, click the Startup tab, right-click the disabled program, and select Enable. You can also re-run the Startup Cleaner tool and generate a script that re-enables specific items. On macOS, go to System Settings > General > Login Items and add the application back. On Linux, re-enable the systemd service with systemctl --user enable servicename or restore the .desktop file to your ~/.config/autostart directory. Changes take effect after the next reboot.
Does this help with slow performance after booting?
Yes -- startup programs do not just slow down the boot process, they continue consuming CPU, memory, and disk I/O after your desktop appears. When you log in and your computer feels sluggish for the first few minutes (slow to open programs, laggy mouse, disk thrashing), that is typically caused by 15-30 startup programs all competing for system resources simultaneously. Disabling unnecessary startup items reduces this contention, so your computer becomes responsive faster after logging in. For additional system cleanup, use the
Duplicate File Finder to free up disk space, which also improves overall performance when your drive is nearly full.
Is this the same as Windows Task Manager's Startup tab?
The concept is similar, but this tool goes further in several ways. First, it works across all three major operating systems (Windows, macOS, Linux), not just Windows. Second, it checks multiple startup locations -- Windows Task Manager only shows the Startup tab entries, but programs can also auto-launch via Scheduled Tasks, Run registry keys, and Services. This tool's scan covers all of these locations for a more complete picture. Third, it provides a shareable script you can save and re-run, which is useful for IT support scenarios where you need to clean up multiple computers with the same configuration.
