An open PowerShell module for Windows that carries out system tuning through individual functions you can call one at a time, updated to 8.0.0 in October 2026 with support for Windows 11 25H2 and released under the MIT licence.

A driver store manager for Windows that lists the third party driver packages kept on the system in a sortable table, shows size and date, deletes old versions in batches, exports a backup and can select unused drivers automatically. The code is published under GPL.

RegShot is an open source registry comparison tool under LGPLv2: take a snapshot before a change and another after, then compare the two to list added, removed and modified keys. It is widely used to audit what an installer touched.

Hundreds of community modifications, each installed with one click, each removable without a trace: the old craft of bending Windows turned into something a cautious person can try.

Queue a hundred programs, press once, and walk away. BCUninstaller removes silently in batches, then scans the registry and disk for what the vendor installer left behind. Free and open source.

System Informer 4.0.26241 is a free open source system tool that watches resources, debugs software and hunts malicious behaviour, with charts you can rewind and handles you can search.

Ant Renamer 2.13.0 is a free open source batch renamer for Windows that stacks actions such as extension changes, character edits, numbering, regular expressions and EXIF or ID3 metadata into one run.

Files 4.2.9 is an open source file manager for Windows under the MIT licence, with tabs, a dual pane, three cloud services wired in and Git integration built into the window.

It hunts down software that other uninstallers never list, from portable programs to packages and store apps, then removes any number of them in one batch. The licence asks nothing, not even for company use.

No button at all, just a batch script that walks through numbered stages, logs every one of them and lets each be switched off from the command line. One full pass is officially a 3 to 10 hour job.

A cleaner whose whole argument is that you should see the files before they go. Ticking items yourself, a preview list with paths and sizes, cookies you can exempt, and a current release that folds AI client caches into ordinary maintenance.

An open-source tool that sets screen colour temperature from the local sunrise and sunset, with exact Kelvin values for day and night, a transition you can time yourself, per-application exemptions and global hotkeys. Fully offline.
