This is a simple application that performs a hack to the Windows Registry that enables you to hide or show users from the Windows logon screen. I wrote this program for me, as on this computer I have a user account set up for people to do audio editing and web browsing only, making sure that all my lovely documents stay hidden from view. The thing is that this user account is not used all the time, only on special occasions, which left me with two options. Either I could delete the account and reinstate it when the need arose, or I could put up with having two accounts on the computer, one a dormant one. Or there was a third option; thanks to the wonders of t'interweb, I had a bit of a search around and came across a Windows Registry hack that would hide users from the list. It said it was for Windows XP, but I thought I might as well try it with Vista also. It worked! So, I could switch this account on and off at will, and all it required was to dip into the registry each time I needed to. Bit I'm a lazy bastard, and decided that it would be so much easier if I could do this without having to go into the registry, which had the added disadvantage that if I needed to do something else in there, I would lose the right place. (Actually, I had already covered that eventuality by placing a text file with the key in it, but that's not the point I'm trying to make here.) So WiHi Shus was born. Using WiHi Shus is simple - all you have to do is type in the name of the user you wish to hide or show, check the box next to 'Hide' or 'Show' depending on what you want to do, and click the big button marked 'Do It'. Click 'Yes' to confirm, and hey Presto, that user is how hidden or unhidden depending on which choice you made earlier on. IMPORTANT: It is quite obvious that you should not do this to all your users.
