The problem with most system administrators is that they think that the users or Hackers too are stupid. Almost all system administrators use the Registry Trick to hide all drives in My Computer. So in order to unhide or display all drives, simply delete that particular key.
Some systems have the floppy disk disabled through the BIOS.

On those systems if the BIOS is protected, you may need to crack the BIOS password. . Sometimes making drives readable (Removing R +) and then creating Shortcuts to them also helps us to get access to them.

Further Changing your Operating System's Looks by editing .htt files

If you have installed Windows Desktop Update and have the view as Web Page option enabled, you can customise the way the folder looks by selecting View > Customise this folder. Here you can change the background and other things about that particular folder. Well that is pretty lame, right? We hackers already know things as lame as that. Read on for some kewl stuff.

Well, you could also change the default that is stored in a Hidden HTML Template file (I think so..) which is nothing but a HTML document with a .htt extension. This .htt file is found at: %systemroot%\web\folder.htt.

The %systemroot% stands for the drive in which Windows is Installed, which is normally C:
You can edit these .htt files almost just like you edit normal .HTM or .HTML files. Simply open them in an ASCII editor like Notepad. The following is a list of .htt files on your system which control various folders and which can be edited to customise the way various folders look.

controlp.htt Control Panel

printers.htt Printers mycomp.htt My Computer

safemode.htt Safe Mode

All these files are found in the web folder in %systemfolder%. The folder.htt file has a line:

'Here's a good place to add a few lines of your own"

which is the place where you can add your own A HREF links. These links would then appear in the folder whose folder.htt file you edited. All this might sound really easy and simple, but you see these .htt files do not contain normal HTML code, instead they contain a mixture of HTML and web bots. Hence they can be difficult for new people.
