Challenge 2: Which Tools Are Actually Usable on Windows -- Solution
Walkthrough

All six tools can be included in some form, but they split into two
genuinely different answers depending on category.

Usable natively, end to end, on Windows:
- Cap -- explicitly cross-platform (Windows, Mac, Linux), so this is
  the one capture-time recorder in the course actually installable
  and usable on Windows itself.
- DemoPolish -- web-based; it never runs a native app on your own
  machine at all, it only needs an existing recording to upload,
  which can come from any OS.
- Trupeer -- same reasoning as DemoPolish: web-based, OS-agnostic on
  input, works regardless of what recorded the raw footage.
- Descript -- explicitly supports Windows alongside Mac, so this is
  fully usable natively too.

Not usable natively on Windows:
- Screen Studio -- Mac only, per the OS-coverage map; there is no
  Windows version and, per the chapter's own research, no planned
  one either.
- Screenify Studio -- also Mac only, same limitation as Screen
  Studio.

Reasoning for the two web-based tools deserves its own note: DemoPolish
and Trupeer aren't "usable on Windows" in the sense of running Windows
software -- they're OS-agnostic by construction, since the actual
processing happens on their own servers, not on your machine. A
Windows user can record with Cap (or any other Windows-compatible
recorder) and then feed that file into either pipeline without ever
touching a Mac.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that the reader correctly applies the chapter's
own OS-coverage table to a Windows-specific scenario, and recognizes
the important nuance that "web-based" tools aren't restricted by the
recording OS at all -- only the capture-time recorders carry a real
OS constraint, and only two of the three of those are Mac-only.
