Changing the icons used by Sumatra PDF reader

Question

I like the simple design of Sumatra PDF reader, but the ugly icons it uses are ugly my question is how to replace them.

Specifically how do I replace:

The icons used in file explorer beside pdf files/files opened by Sumatra.

The icon used to represent Sumatra in the taskbar, all programs and so on.

Notes

• I am using the 64-bit windows version of Sumatra (Windows 10 ).

Answer 1

You will need to hack the executable (.exe) and find and replace the icons by ones of the same size.

You could use a tool such as Resource Hacker or any one of its alternatives. An icon-painting tool might be useful.
