Arduino Logo appears blurry in the toolbar W8.1

Hi,
I've notticed that in my Windows 8.1 computer, the Arduino Logo that appears in the toolbar is very blurry, but in the desktop its all OK. The first image is from the toolbar, and the second one from the desktop.

Yeah, it seems like it is using the 16x16 version of the icon. Could it have something to do with the fact that is the same icon resolution used in the top left corner of the window?

Yes, indeed. It's ugly. That icon is in file IDE\lib\arduino_icon.ico. AFAIK, it's correct. Nonetheless it's ugly so there is something I don't know. I'm no windows hacker and I need some help

[ffissore]

Right path is IDE\lib\arduino_icon.ico

Maybe it's sufficient to just replace the icon with an hi-res one?

That's the conundrum: that .ico already includes different resolutions of the same icon. Windows is picking up the wrong one when putting it into the app bar. I don't know why

[carlosperate]

I had quick play with Resource Hacker and the arduino executable. I opened the .exe file and replaced the icon files with a different one, replaced the arduino icon in the lib folder, and reset the thumbnail and icon cache on Windows.

Basically the windows explorer arduino.exe icon comes from the icons stored into the assembled .exe file, and the taskbar and window icon (the one displayed on the top left corner when the arduino window is opened) come from somewhere else.

This post on stack overflow suggests that:

Windows uses the Assembly icon when pinned, and the window icon when unpinned

Which seems to be correct in this case, as the arduino.exe pinned icon (for the original or the modified one) is the assembled full resolution icon.

Do you have a fix then?
