Windows comes preloaded with different settings, programs and drivers that interact simultaneously to make your PC run smoothly. Unfortunately, this mixed environment typically leads to compatibility issues and software conflicts that manifest in different ways.
The result is that updates may fail to install, or Windows may struggle to start up properly, often leading to slowdowns , freezing, BSODs or crashes.
Performing a clean boot disables all non-essential services to help you find any underlying software conflicts or issues in your PC. In this guide, we’ll define a clean boot, when to use it and how to clean boot in Windows 10.
What Is a Clean Boot?
A clean boot is a diagnostic approach that involves disabling non-essential services in Windows and starting the system with a minimal set of essential startup programs and drivers. This way, you can determine and isolate what app or program is causing the issues you’re experiencing while using your PC.
Performing a clean boot is akin to starting Windows in Safe Mode . A clean boot gives you more control over which programs and services run at startup. It also helps isolate the elements of the normal boot process that are causing performance problems without deleting your personal files . Safe Mode, on the other hand, is recommended when your PC has issues related to software, hardware or drivers.
When Should You Perform a Clean Boot in Windows 10?
A clean boot is useful in the following instances:
- When your computer doesn’t start normally
- If you receive errors at startup that you can’t identify
- When an official Windows Update won’t install properly
- When you’re experiencing frequent app crashes
To diagnose the problem, perform a clean boot and then enable one service at a time (followed by a reboot) until you find the service that is causing your issue.
