GTweak

What it is

A portable Windows desktop utility that gathers system tweaks into one interface: disabling telemetry and update services, removing preinstalled apps, OneDrive, Edge, and AI assistants like Copilot and Recall, and adjusting the taskbar, themes, and input settings. It also clears RAM and temporary files, applies power plans, shows hardware information, and runs custom scripts with TrustedInstaller privileges. People setting up a fresh Windows install use it to strip out bloat and data collection without editing the registry by hand.
