IMPORTANT: This mod has been moved to the official Windhawk repository. As such, this post is likely to be outdated.
FINALLY, I've made a mod which FULLY restores 32px icons in Explorer.
Pros:
- Works in every Explorer SysListView32, whether it be main Explorer, 64-bit open/save, or 32-bit open/save
- "Medium icons" will be selected in 32px icons mode
- Windhawk mod. Completely native. No AHK or weird COM interfacing.
Cons:
- Not known!

Prerequisite mod (2023/10/07)
As of now (2023/10/07), there is a bug in Windhawk's symbol hook system which makes mods that hook symbols crash on x86 (32-bit) programs.
You MUST install this mod, or else EVERY 32-bit application (INCLUDING THE WINDHAWK UI AND THE WINDHAWK ENGINE ITSELF) will CRASH.

# Explorer 32px Icons
Beginning with Windows Vista, the "Medium icons" view (previous just "Icons") uses
icons that are 48 pixels in size, instead of the previous 32 pixel size. This mod
restores the 32 pixel size.
# IMPORTANT
You **must** be using Explorer with the SysListView32 view enabled for this mod to work.
The default DirectUI view will not work.
