7-Zip: How to change 7zip icon?

Is this for an installed version, or for the icon that appears in the menu?

Installed:
Use the program Resource Hacker to open the 7zFM.exe, find the resource under ICONGROUP that contains the icon, and replace it with yours.

Portable:
Use a program like IcoFX to create the proper .ico file (48x48, 32x32, 16x16 in both true color and 256 color), save the file as appicon.ico in 7zipPortable/App/AppInfo, use NSIS Portable to recompile 7zipPortable.nsi from the 7zipPortable/Other/Source directory

after 4 hours, trying every method out there, Logging-off after each.

I found this by-far the most easy, convenient and safe way to change the ugly 7-zip Icons:

http://thatnetsite.com/2009/04/replacement-icons-for-7-zip-ver-2/

follow the instructions, I worked this on Vista Home SP2 32bit

after following instructions and Log-off/log-in you will see the icons for Archives have changed to Golden Icons, these icons are placed in "C:\Program Files\7-Zip\icons" folder. you may want to Back-up this folder.

if you want to change one of the icons, let's say you want to change the RAR archives, just rename your created/downloaded icon to rar ( or whichever extension you want to change) and copy the icon to "C:\Program Files\7-Zip\icons" and replace when promoted. Log-off/Log-in.

here is one site to convert PNG to .ico : http://www.convertico.com/

all files and links provided are safe, I tested them myself.

I really hope you won't go round and round like I did, so I hope this helps you people.
