I have an exe file that suddenly changed from its normal correct program icon to a generic blank page program icon. If I change the name of the program file, or move it to another folder, the correct icon comes back. If I change the name back, or move it back to the original folder, the icon goes generic again.I already tried deleting and rebuilding the system icon cache.Any idea what else could affect one single program icon in one single folder?
Found a solution from 2011, originally for the same problem in Win7: reboot Windows in Safe mode, look at the folder with the faulty program icon, and it will be fixed. Remains fixed when the system is rebooted in normal mode. Good old Microsoft, bringing you reliable Windows software since 1984.
