Windows 10: Can I have png as icons in Win 11 ? I use to replace my icons in Windows 8, 10, and 11 with...

I use to replace my icons in Windows 8, 10, and 11 with png icons 512x512 px. Lately I have not been able to change any folder icon from an .ico to a .png icon. Does Windows 11 no longer support png files as icons ? If this is due to a corruption in Windows 11 or if there is a hidden setting to be able to use png files as icons could you please tell me. I do not want to convert png icons to ico. Please let me know of a workout. My Windows 11 is up to date all updates up to July 16,2023Win11 Version 22H2 OS Build 22621.1992PS. I have run sfc /scannowDISM.exe /Online /Clean

Windows 10 desktop icons not in order

In ccleaner, did you uncheck cleaning the icon cache... have not used in a while; however, I think that is what the option is called.

Now, if you are setting the icons and they move after you have set the settings and not changed them... you may have the "Random Windows 10 Icon movement problem".
Some people have this and some don't.

Here is a thread on the problem at Windows10 forums: Windows 10: Folder View Settings and Desktop Icon Positions Not Saving

Using Windows 11 icons on Windows 10

So I liked the new Windows 11 icons better than the ones on 10, but wasn't ready to upgrade yet. So I went on to investigate how to change them. So far I have tried couple of ways and was wondering if there are other ways.
I extracted the icons in separate icon files from Windows 11 .dll files and generated a .reg file to set them in [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons]. But this only handles shell32.dll icons, can imageres.dll icons be replaced this way?
Other thing I tried with a VM is to just replace imageres.dll.mun, shell32.dll.mun and zipfldr.dll.mun in systemresourses directory with the Windows 11 counterparts. This seems to work, icons changed and the system still works, but I'm a bit hesitant with this as there are some icons missing from Windows 11 files that are present in Windows 10 files and what other stuff do these dll.mun files hold?
So are these valid ways to do this or are there other easy ways?
