Use msconfig to effectively diagnose Windows startup problems. Its core functions are implemented through five tabs: 1. Select Diagnostic startup or Selective startup in the General tab to troubleshoot startup conflicts; 2. The Boot tab sets Safe boot to enter safe mode or adjusts startup timeout; 3. The Services tab checks "Hide all Microsoft services" and disables suspicious third-party services; 4. The Startup function has been moved to the Task Manager, and the startup items need to be managed through the Task Manager; 5. The Tools tab provides system tool shortcuts. When performing a clean boot, you should cancel the loading of the startup item and disable non-Microsoft services, and enable it step by step to locate the problem. Be sure to restore the original settings after use to avoid disabling system services at will in case of system abnormalities. Under correct operation, msconfig is a powerful troubleshooting tool, but should not be used as a daily optimization method.

The System Configuration (msconfig) utility in Windows is a built-in tool that helps you troubleshoot startup issues, manage boot settings, and control which programs and services load when Windows starts. While it's not meant for everyday use, it can be very helpful when diagnosed performance problems or resolving conflicts.

Here's how to use msconfig effectively and safely.

How to Open msconfig

There are a few quick ways to open the System Configuration tool:

• Press Win R to open the Run dialog, type msconfig , and press Enter.
• Type "msconfig" in the Start menu search bar and click the result.
• Open Command Prompt or PowerShell and type msconfig .

?? Note : You may need administrator rights to make changes. If prompted by UAC (User Account Control), click Yes.

Understanding the msconfig Tabs

Once opened, msconfig has several tabs. Here's what each one does and how to use it.

1. General Tab – Control Startup Settings

This tab lets you choose how Windows starts:

• Normal startup : Loads all device drivers and startup services (default).
• Diagnostic startup : Starts Windows with minimal drivers and services—useful for isolating software conflicts.
• Selective startup : Lets you manually choose what to load, including startup items and services.

? Tip : If Windows is slow or crashes at startup, try Diagnostic startup , then re-enable items gradually to find the culprit.

2. Boot Tab – Manage Operating System and Boot Options

Use this tab to:

• Adjust boot timeout (how long the system waits before loading the default OS).
• Enable Safe Mode for troubleshooting.
• Change advanced boot options like number of processors or boot logging.

? Common use case :

• If you're troubleshooting driver or startup issues, go to the Boot tab → check Safe boot → choose Minimal → Apply → Restart.

? After troubleshooting, return to msconfig and uncheck Safe boot to return to normal operation.

3. Services Tab – Control Background Services

This tab shows services that start with Windows.

• Check "Hide all Microsoft services" to avoid disabling critical Windows components.
• You can then disable third-party services (eg, printer software, updaters) that may be slowing down startup.

? Best practice : Only disable services you recognize and don't need at startup. When in doubt, leave them enabled.

4. Startup Tab (in older Windows versions)

?? Note : In Windows 10 and 11, the Startup tab was removed from msconfig and replaced with the Startup section in Task Manager .

• To manage startup programs now, press Ctrl Shift Esc to open Task Manager → go to the Startup tab.
• You can enable or disable apps from launching at startup here.

But msconfig still indirectly affects startup via services and boot settings.

5. Tools Tab – Quick Access to System Utilities

This tab lists useful Windows tools like:

• Command Prompt
• Registry Editor
• System Restore
• Event Viewer
• Disk Cleanup

You can:

• Select a tool
• Click Launch to open it
• Or click Open file location to find its shortcut

This is just a shortcut menu—doesn't change system behavior.

When to Use msconfig

Use msconfig when:

• Windows fails to start properly.
• You suspect a startup program or service is causing crashes.
• You need to boot into Safe Mode.
• You want to perform a clean boot to isolate software conflicts.

? Clean Boot Tip :

1. Open msconfig.
2. Go to General → Select Selective startup .
3. Uncheck Load startup items .
4. Go to Services → Check Hide all Microsoft services → Click Disable all .
5. Click Apply → OK → Restart.

This gives you a clean environment. Re-enable services in groups to find the problem.

Important Warnings

• Don't disable services blindly —you might break essential functions.
• Avoid changing boot settings unless you know what you're doing.
• Always revert changes after troubleshooting (especially Safe Mode or selective startup).

If you make a change and Windows won't start, you can often boot into Safe Mode and reopen msconfig to undo it.

Using msconfig wisely can help you diagnose and fix startup problems quickly. Just remember: it's a troubleshooting tool, not a routine optimization utility.

Basically, stick to what you understand, and when in doubt—don't disable system-level items.
