The Hilton Hhonors account information is typically not stored in cookies unless there was some type of "remember me" option on the web site that I have overlooked. However, the information is cached in memory. tasnam, if you had several instances of Explorer open, please be sure to close all instances in order to clear memory. If, for some reason, clearing memory fails to do the trick, cookies may be eliminated by deleting all *.txt files from the \windows\cookies subdirectory.
