## Summary of the Pull Request
This actually fixes an issue with #39794. What I failed to mention in
the original issue was the additional path under the registry that the
new key is located under. Instead of the key being stored directly in
`UserChoiceLatest` in a key named `ProgId`, the path also includes a
second `ProgId` as well.

Copilot tried to fix this issue in #40035, but because I had failed to
mention the additional `ProgId` in the path, it was not included in
Copilot's fix.

Therefore, the true new path is 
`.../UserChoiceLatest/ProgId`

PowerToys Source Code

Code organization

The PowerToys are split into DLLs for each PowerToy module (modules folder), and an executable (runner folder) that loads and manages those DLLs.

The settings window is a separate executable, contained in settings-ui folder. It utilizes a WebView to display an HTML-based settings window.

The common contains code for a static library with helper functions, used by both the runner and the PowerToys modules.
