Oh, thank you very much. I really needed that information, now I will be able to use some icons I need. Thanks again :)

It works, thanks.

Hi,
Thanks for the Reg key. I just want to know if you found a solution for the icon.
There is a post on 11F about the assets that might be helpful:

As I realized, MS use "Segoe Fluent Icon" and "Segoe MDL2 Assets" fonts for some part of Windows UI.

These two links might be helpful, too:
