>I do not know where it came from. I assumed it was win98 utility, but it allowed me to modify user interfaces icons, buttons, etc. One of the utilities in there refreshed all windows icons, including office shortcut which periodically turns black. I do not know where it came from and how it got removed!

Sounds like you're refering to TweakUI, a utility that comes with the Windows9x Power Toys. You should be able to find it at the Microsoft web site.
