Options
- ASafe Mode
- BAutomated System Recovery
- CLast Known Good Configuration
- DSystem Restore
Explanation
System Restore allows Windows to roll back system files, registry settings, and installed programs to a previous restore point - effectively undoing recent changes that may have broken the application. Since the program worked yesterday, using System Restore to revert to a point from before the issue occurred is the most targeted and appropriate fix. Safe Mode is used to diagnose startup issues, not repair applications. Last Known Good Configuration is a legacy boot option (relevant mainly in Windows XP) that restores registry hive settings at login, but it does not restore user-level application states. Automated System Recovery is a more drastic full-system backup restore, not suited for a single application issue.
