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
- Select your operating system -- Windows, macOS, or Linux. Each platform stores startup programs in different locations: Windows uses the Registry and Startup folder, macOS uses Launch Agents and Login Items, and Linux uses systemd user services and XDG autostart entries. The tool generates platform-specific scripts that know exactly where to look for each OS.
- Choose between Scan First mode and Disable Selected mode. Scan First generates a read-only script that lists every program configured to launch at boot without changing anything -- this is the recommended starting point so you can see exactly what is running. Disable Selected mode lets you pick specific programs to remove from startup and generates a script that makes those changes. Always scan first if you are not sure what is running on your system.
- Review the list of common startup items and select the ones you want to disable. The tool identifies programs that are generally safe to disable, such as auto-updaters for software you rarely use, cloud sync clients you do not need running constantly, and manufacturer bloatware that shipped with your PC. Each item includes a brief description so you can make an informed decision. If you are unsure about an item, leave it enabled -- you can always come back and disable it later.
- Copy the generated script and run it in your terminal to apply the changes. On Windows, open PowerShell as Administrator (right-click Start > Terminal Admin). On macOS, open Terminal from Applications > Utilities. On Linux, open your distribution's terminal emulator. The script disables each selected item and confirms the change. A reboot is required for the changes to take effect, so restart your computer after running the script to see the improvement in boot time.
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.
