Need help identifying two Registry KeyNames

Question

Greetings all, I'm working on optimizing our VDI environment for Windows 10 20H2 and was looking at suggested settings from Microsoft here: https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/rds-vdi-recommendations-2004

There are a couple registry tweaks that are listed and I couldn't find any information regarding what the actual registry change does for the following registry key names:

ShellState: HKLM\Temp\Software\Microsoft\Windows\CurrentVersion\Explorer
ShowCompColor: HKLM\Temp\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

In the document, it advises to set ShellState to 240000003C2800000000000000000000 and ShowCompColor to 1 Would anyone know what these key names pertain to and what the suggested tweak would change? Cheers and thanks in advance.

Answer 1

ShowCompColor is described at GlobalFolderOptions element
ShellState is defined in a structure (SHELLSTATEW structure)
(not easy to find which bits are set apart by using SHGetSetSettings in a program (C++, VB, C#, ...))
