thank you for info I didn't knew.
So I'm stuck and I make some attempts to edit shell32.dll.mui with icon in syswow64 then
I'm not aware of latest changes according to builds , I noticed for example in RS5 1809 ( on my other work laptop ) there is no more shell32.dll.mui in syswow64 .
EDIT: no way , doesn't seem to change anything despite modded shell32.dll.mui .
I gave up and just messed to hide commandbar lol
