System.Drawing.SystemIcons.Shield icon is incorrect in Windows 7 and above

[aquinn39]

.NET version

7.0

Did it work in .NET Framework?

No

Did it work in any of the earlier releases of .NET Core or .NET 5+?

Not sure. Also unsure if it worked in .Net Framework or not.

Issue description

According to https://learn.microsoft.com/en-us/dotnet/api/system.drawing.systemicons.shield, the shield icon should be used on any control whose default action requires elevation to administrator privileges. Looking at https://learn.microsoft.com/en-us/windows/win32/uxguide/winenv-uac, the shield icon used to indicate elevation is required is a blue and yellow shield whereas SystemIcons.Shield, despite being recommended for controls whose default action requires elevation, uses a red, green, blue and yellow shield icon as you can see in the image below:
.
If we look at some UIs in Windows 11, it uses a blue and yellow shield as expected:

It seems that the icon used in System.Drawing.SystemIcons.Shield is actually the older icon from Windows Vista:

Whereas it seems to have been changed in to the blue and yellow in Windows 7 and above, but the one in System.Drawing.SystemIcons.Shield was never updated:

Steps to reproduce

Show System.Drawing.SystemIcons.Shield anywhere in a UI.

This is not a Windows Forms issue, these icons are defined in dotnet/runtime -> https://github.com/dotnet/runtime/blob/main/src/libraries/System.Drawing.Common/src/System/Drawing/SystemIcons.cs

Ok so should I move this to the https://github.com/microsoft/dotnet repo then?

Move it to https://github.com/dotnet/runtime

The Windows Forms team can do it once they triage the issue.

@RussKie we will take care of this on end - System.Drawing is moving into this repo and we'll be handling all of the issues moving forward. This is likely a duplicate of an earlier issue in the current System.Drawing home.

@JeremyKuhne believes there's an active issue on this, and will look it up.

Here is the existing issue: #8842. I've created an official API proposal to deal with this.
