How to Use the System Configuration Utility (msconfig) in Windows
Control boot options, startup mode, and services for troubleshooting with msconfig.
Overview
System Configuration (msconfig) lets you manage boot settings, startup mode, and services — invaluable for troubleshooting startup problems and performing a clean boot. This guide covers how to open and use it in Windows 10/11 (and 8.1).
The System Configuration (msconfig) utility.
Key Takeaways
- msconfig manages boot, startup mode, and services.
- Use "Diagnostic"/"Selective" startup for a clean boot.
- Safe boot options help troubleshoot.
- Startup apps are managed in Task Manager on newer Windows.
Open System Configuration
1. Press Windows + R, type msconfig, and press Enter.
2. Or search "System Configuration" in the Start menu.
3. Or run msconfig from Command Prompt.
General Tab: Startup Modes
- Normal startup — load everything (default).
- Diagnostic startup — basic devices/services only (like a deep clean boot).
- Selective startup — choose whether to load system services and startup items.
Boot Tab: Boot Options
1. Select the OS entry (if multiple) and set the default.
2. Tick "Safe boot" and a mode (Minimal, Network, Alternate Shell) to boot into Safe Mode.
3. Set a Timeout for the boot menu.
4. Untick Safe boot afterward to return to normal booting.
Services and Tools Tabs
1. Services: hide Microsoft services, then disable third-party services for a clean boot.
2. Tools: launch built-in utilities (Event Viewer, Command Prompt, etc.) from one place.
3. On Windows 10/11, manage Startup apps via Task Manager (linked from the Startup tab).
Perform a Clean Boot
1. On the General tab, choose Selective startup and untick "Load startup items".
2. On Services, tick "Hide all Microsoft services", then Disable all.
3. Apply, restart, and test — this isolates third-party conflicts.
4. Re-enable in groups to find the culprit, then restore Normal startup.
Troubleshooting
Problem: Stuck booting into Safe Mode.
Solution: Reopen msconfig and untick "Safe boot" on the Boot tab, then restart.
Problem: Startup tab is empty.
Solution: On Windows 10/11, startup apps moved to Task Manager > Startup — manage them there.
Problem: Something broke after disabling services.
Solution: Re-enable services in groups to find the needed one, then return to Normal startup.
Problem: Changes didn’t apply.
Solution: Click Apply and restart; msconfig changes take effect on reboot.
Conclusion
msconfig is a key troubleshooting tool: it controls boot options, startup mode, and services, and makes performing a clean boot easy. Use Selective/Diagnostic startup to isolate problems — and remember startup apps now live in Task Manager on modern Windows.
