Introduction
When your computer is experiencing issues, booting in Safe Mode can be a lifesaver. This alternative boot mode allows you to troubleshoot and diagnose problems without the hassle of dealing with unnecessary system processes and drivers. But have you ever wondered what happens when you boot your PC in Safe Mode? In this article, we’ll delve into the inner workings of Safe Mode, exploring what changes occur, how it affects your system, and what you can expect when you boot your PC in this mode.
The Concept of Safe Mode
Safe Mode, also known as Safe Boot, is a diagnostic mode that loads a minimal set of system files and drivers, allowing you to access your PC without the overhead of unnecessary system processes and startup programs. This mode is designed to help troubleshoot issues such as:
- Driver conflicts
- System crashes
- Malware infections

* and others
are disabled. This reduction in system overhead helps to identify whether a specific service or driver is causing issues.
Startup Programs
All startup programs, including those launched through the Windows Registry, Task Scheduler, or Startup folder, are disabled in Safe Mode. This allows you to isolate whether a specific program is causing problems during boot.
Network Connectivity
In Safe Mode, network connectivity is limited, and you may not be able to access the internet or connect to a network. This disconnection from the internet helps to prevent malicious software from spreading or communicating with their command centers.
What You Can Do in Safe Mode
While in Safe Mode, you can perform various tasks to troubleshoot and diagnose issues:
Run System File Checker (SFC)
The System File Checker (SFC) is a built-in utility that scans and replaces corrupted system files. Running SFC in Safe Mode can help fix corrupted files that might be causing issues.
Run DISM
The Deployment Image Servicing and Management (DISM) tool can be used to repair corrupted system files, registry entries, and Windows system components.
Disable and Re-enable Devices
In Safe Mode, you can disable and re-enable devices to identify whether a specific hardware component is causing issues.
Run Antivirus Scans
You can run antivirus scans in Safe Mode to help detect and remove malware that might be hiding behind system processes.
Limitations of Safe Mode
While Safe Mode is a powerful diagnostic tool, it’s not without its limitations:
Performance
Safe Mode can significantly reduce your system’s performance, making it unsuitable for resource-intensive tasks.
Limited Functionality
Many system services and features are disabled in Safe Mode, which can limit your ability to perform certain tasks.
No Access to Hardware
In Safe Mode, some hardware components, such as USB devices or network cards, might not function properly or at all.
How to Boot in Safe Mode
Booting in Safe Mode varies depending on your operating system:
