Hello there, I use Icon Packager 10 on Windows 11 and it works to change all the icons that I want perfectly. The only issue that I have is some icons (not the ones that I changed) like program icons then display a white/blank icon.
At first I thought it was those few programs then one time I formatted Windows and those some program icons were fine until I installed Icon Packager. I am guessing there is some compatibility issue with Windows 11.
This program is amazing and hasn't been updated in ages, I hope Stardock can come up with an update Icon Packager 11 I am happy to pay for it.
