starfall, open up any system window (e.g. start menu > computer).
once you in there, click on 'organize' and go down to 'folder and search options'.
click on the 'view' tab.
all you need do now is locate the folder icon labeled 'hidden files and folders'.
this will have 2 options:
dont show hidden files, folders, or drives.
show hidden files, folders, and drives.
i'll leave you to work out the rest....
edit: lol, harpo beat me! hehe
