Safe Mode
Definition
A diagnostic Windows startup configuration with minimal drivers and services.
Detailed explanation
Safe Mode is a diagnostic Windows startup configuration that loads a minimal set of drivers and services. It commonly uses basic display, storage, keyboard, and mouse support while omitting many vendor services and startup applications. Its reduced environment helps distinguish dependencies but is not itself a repair operation. Networking is optional in a separate Safe Mode variant, and Microsoft’s basic display path commonly replaces accelerated vendor graphics. Because many filters, services, and startup applications are absent, behavior there demonstrates environmental dependence without proving which omitted component is responsible.
