CrapFixer
Fixes the crap Windows leaves behind
CrapFixer is a lightweight Windows cleanup and tweaking toolbox aimed at removing or reducing the everyday “junk” Windows accumulates, while keeping changes understandable and reversible. It’s positioned as a fast, no-fluff utility that focuses on practical fixes rather than turning into an overstuffed “optimizer” suite.

It distinguishes between items that are recommended to fix and items that are already optimized, helping you avoid unnecessary changes. The project emphasizes safety by making most tweaks undoable, and it supports running with administrator privileges when deeper changes (like certain registry locations) are required. For users who want more clarity, it includes a help lookup per tweak and offers log review so you can understand what happened and share results for troubleshooting. -
