I'm looking for a reference that lists the possible entries under the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons
Entries under this registry key override the default icon used for various purposes in the Windows UI. Looking online I've found two so far:
- 29 – Shortcut Arrow overlay icon
- 179 – "Blue arrows" icon overlay for compressed files
Presumably Microsoft would have this list somewhere, but finding a comprehensive reference for Windows 10 has eluded me so far.
Edit
I did some more experimenting by adding more number keys and pointing each to a unique icon. Here's the associations I've found so far:
3 normal folder icon
8 fixed drive folder icon
11 removable drive folder icon
15 network drive icon in the explorer address bar
29 shortcut overlay icon
34 explorer navigation pane root icon labelled 'Desktop'
51 network folder icon
77 UAC (administrator) overlay icon
107 os drive folder icon
179 compressed file/folder overlay icon

Copy shell32.dll and imageres.dll in the System32 folder to a folder of choice, then use 7-Zip or other archiver to unpack the dll file, once that is done dig into the .rsrc folder to find the ICON folder, in there you will find the icons and numbers.
The registry entry should you wish to create one would look something like this
"DisplayIcon"="C:\Windows\System32\shell32.dll,9"
or
"DisplayIcon"="C:\Windows\System32\imageres.dll,9"
