It supports defining arbitrary zone layouts, switching between different layouts with hotkeys, snapping windows to them using the mouse or hotkeys, remembering which zone a window was in, snapping child windows/popups to zones.
It doesn't lock windows in place or remove window decorations unfortunately.
There's some other great stuff in PowerToys as well, they can all be enabled optionally.
* Bulk file rename in the context menu. Rename large numbers of files in a UI using regex/pattern matching.
* File lock viewer: See which process is preventing a file being deleted.
* PowerToys Run: basically spotlight or a system wide version of vscode's command bar. It can do calculations, find files, launch programs. Bound to a global hotkey of alt+space.
* Text extractor: like snipping tool but tries to use OCR to extract text from the capture region.
