1. Introduction
Safe Mode and the Windows Recovery Environment (WinRE) are built-in troubleshooting tools in Windows that help fix system issues, remove malware, and recover an unbootable system.

- Safe Mode starts Windows with minimal drivers and services, allowing users to diagnose and fix issues.
- Windows Recovery Environment (WinRE) provides advanced repair options, including system restore, command prompt, and startup repair.

Below is a detailed guide on both features.

2. Understanding Safe Mode

Safe Mode is a diagnostic startup mode that loads only the essential drivers and services needed for Windows to function.

A. Types of Safe Mode
Windows offers three types of Safe Mode:

1. Safe Mode – Loads Windows with only essential drivers.
2. Safe Mode with Networking – Includes internet and network drivers, useful for online troubleshooting.
3. Safe Mode with Command Prompt – Opens directly to the Command Prompt instead of the graphical interface.

B. How to Boot into Safe Mode

  • Press Win + X, then select Shut down or sign out > Restart while holding Shift.

  • In the recovery menu, go to Troubleshoot > Advanced options > Startup Settings.

  • Click Restart.

  • Press 4 for Safe Mode, 5 for Safe Mode with Networking, or 6 for Safe Mode with Command Prompt.



Method 2: Using System Configuration (msconfig)
  • Press Win + R, type msconfig, and press Enter.

  • Go to the Boot tab.

  • Check Safe Boot and select Minimal, Network, or Alternate shell (Command Prompt).
