How to change a program (exe) icon...


1. Since most exe programs has been compressed, we need to unpack using any unpacker programs.
e.g.,  upx -d -o utd.exe  ut.exe

3. Open "icon group", then "Action --> Replace icon".  Load any other exe file as an icon resource. 

e.g., Windows explorer.exe

4. Replace icons, then "File --> Save as".

5. If you want, you can compress the exe file.

e.g., upx -9 -o utc.exe  utd.exe
