What it does

Ranks what is holding the PC back right now — a busy program, a Defender scan — and suggests what to try.

Checks adapter, router, DNS and internet in order, then names the link that failed.

Shows which python, node or java runs when you type it, and why another copy wins.

Sizes package caches and old build folders, and frees the ones unused for months.

Finds files with identical contents and sends the extra copies to the Recycle Bin.

A tiny always-on-top window with CPU, memory, battery and free space.

Feedback shapes what we build next.
