Theme and last update W11 24h2

[tistou77]

Hello all

Themes no longer work with the latest Windows 11 24h2 update (26100.3624).
Finally, everything works, but we can't open an Explorer window.

I assume MS changed something in the aero.msstyle file (no problem with the default theme)
I think we have to use the original aero.msstyle file (26100.3624) and modify everything again.

Since WSB no longer supports the themes (.msstyle file) for Windows 11 24h2, how can we modify the .msstyle file ?
With what software?

Thanks for the help
