Kontext is a Windows shell manager that brings every right-click and File Explorer customization into one place. Windows scatters these settings across 40+ registry locations — context-menu entries, file-type handlers, the Explorer sidebar, "Open With", icon overlays and more — and most tools only reach the obvious ones. Kontext scans them all and shows each entry with its real app name and icon instead of a cryptic GUID, so you can enable or disable anything with a single click. Every change is backed up automatically, so any edit can be undone and restored exactly as it was. It's ideal for cleaning up a cluttered or slow right-click menu and removing leftovers from uninstalled apps.
