Steps to Configure a Windows Clean Boot

Performing a clean boot in Windows involves selectively disabling startup programs and non-essential services to identify software conflicts. This process helps isolate the cause of system issues by loading only the necessary components.

Begin by opening the System Configuration tool. You can do this by pressing `Windows + R`, typing `msconfig`, and hitting Enter. This tool allows you to control startup behavior and services.

Within the System Configuration window, navigate to the Services tab. Here, check the box labeled Hide all Microsoft services to prevent disabling critical system services. After hiding these, click Disable all to turn off all third-party services.

Next, move to the Startup tab. On Windows 10 and later, this tab will redirect you to the Task Manager’s Startup section. Disable all startup items listed here by right-clicking each and selecting Disable. This action prevents these programs from launching automatically when the system boots.

After making these changes, click OK in the System Configuration window. You will be prompted to restart your computer to apply the clean boot configuration. Save any open work and proceed with the restart.

The clean boot state allows Windows to load with a minimal set of drivers and startup programs, which can help identify if a background service or startup item is causing issues.

Restoring Normal Startup After Troubleshooting

Once troubleshooting is complete, it is important to restore your system to its normal startup configuration to ensure all services and programs run as expected.

Reopen the System Configuration tool by pressing `Windows + R`, typing `msconfig`, and pressing Enter. In the General tab, select Normal startup to load all device drivers and services.

Navigate to the Services tab and uncheck Hide all Microsoft services if it remains checked. Then, click Enable all to restore all previously disabled services.

In the Startup tab, re-enable any startup programs you need by opening Task Manager, right-clicking each item, and selecting Enable.

Click OK and restart your computer. This will revert the system to its original startup state, allowing all applications and services to run normally.

Verifying and Troubleshooting After a Clean Boot

Once your system restarts in a clean boot state, it is important to verify the results and proceed with troubleshooting.

Check if the issue you were experiencing persists. If the problem is resolved, it indicates that one of the disabled services or startup programs was causing the conflict. To identify the culprit, you can selectively re-enable services and startup items in groups, restarting your computer after each change until the problem reappears.

Action Purpose Recommended Approach
Enable Services in Batches Isolate the problematic service causing issues Enable 3-5 services at a time, restart, and test system stability
Enable Startup Programs Gradually Identify conflicting startup applications Re-enable startup items incrementally, testing after each batch
Monitor System Behavior Determine if the issue recurs Document changes and symptoms carefully for accurate diagnosis

If the issue persists even after a clean boot, it is likely due to hardware problems or system files corruption. Running diagnostics or using tools such as the System File Checker (SFC) or Deployment Image Servicing and Management (DISM) can assist in further troubleshooting.
