HotkeyScan
Find what program is holding a hotkey on Windows, with the evidence.
...Scan them all sweeps 761 combinations and can keep only the ones held by an owner Windows will not name. A separate Key monitor shows one key three ways (raw input, window messages, hook chain), to tell a faulty key from a program swallowing it.
One 64-bit .exe with the .NET runtime inside: nothing to install, no administrator rights. MIT licence, no ads, no telemetry.
