After around eight quiet months, CrapFixer is finally back. This is not a small update to the old app. The core has been rebuilt from scratch, with one goal: make Windows tweaking simple again without hardcoding the whole app around a fixed collection of tweaks.
A lot of the new CrapFixer comes from what worked best in FluentCleaner Classic: the familiar native interface, the scan-first workflow, clear results, database-driven features and the ability to understand what will happen before pressing the final button.
CrapFixer now uses Wintweak2.ini as a signature database. Add a new signature and CrapFixer can turn it into a category, scan it, show its current state, apply it and restore the Windows default. without recompiling the app
It might actually be one of the first Windows tweakers built this dynamically. At least I have not seen many that work quite like this.
