rundll32.exe is a process which executes DLL’s and places their libraries into the memory, so they can be used more efficiently by applications. This program is important for the stable and secure running of your computer and should not be terminated. Nowadays many virus, Trojans, worms use this to affect the computers. But if you study this process it can be very useful. So I’m starting some tips and tricks on this in coming blog posts.
The syntax for using Rundll32.exe is as follows:
RUNDLL32.EXE <dllname>,<entrypoint> <optional arguments>
The DLL name should not contain any spaces, commas or quotation marks. If the DLL name does contain spaces, use the short (8.3) version of the file name. This is the name which you’ll see if you use that file in DOS environment. Note the comma between the DLL name and the entry point. Also, the name of the entry point function is case-sensitive and there should not be any spaces between the DLL name, the comma, and the entry point function name. Full path of DLL should be given unless it exists in system folders.
There are a number of commands employing Rundll32.exe that can be entered into Start -> Run, a command window, or used in scripts. A common use is to open various Control Panel applets. (Another method specific to Control Panel is discussed here.) For example, to open the Control Panel applet for configuring the display settings enter
rundll32.exe shell32.dll,Control_RunDLL desk.cpl,,3
Different tabs for the Desktop applet can be opened by changing the number at the end that is part of the argument. All of the Control Panel applets and their tabs can be opened this way by using the relevant CPL file and the appropriate tab number as arguments. The operating system also uses this method to display Control Panel. In fact, Control Panel applications are the most commonly mentioned examples in discussions of using Rundll32.exe.

If you accidentally delete the Show Desktop icon from the Quick Launch toolbar, here’s how to get it back:
1. Open Notepad
2. Type these lines, precisely, into Notepad:
3. Save the file on your desktop as “Show Desktop.scf”
You see a new icon on your desktop that looks remarkably like the Show Desktop icon that used to be on your Quick Launch toolbar.
4. Right-click the new icon on your desktop and drag it to the Quick Launch toolbar.
5. Drop the icon wherever you like on the Quick Launch toolbar and choose Move Here. If you choose Move Here, Windows automatically deletes the icon from the desktop.
If there is no icon in Quick Launch toolbar then you won’t be able to move the above way. In that case browse to
“C:\Documents and Settings\Username\Application Data\Microsoft\Internet Explorer\Quick Launch”
Here “Username” is your windows login name. This folder is hidden so just copy above path substituting username and paste it in Windows Explorer adress bar. Press enter and folder will open. Now copy or move the “Show Desktop.scf” to this folder. It will immediately appear in Quick Launch toolbar.
Such problem occurs when you are affected by a w32.USBworm or its varient. Although now there are updates to clean this worm but still you are not able to unhide hidden folders. In such case one of the following registry edits work for sure.
Go to Start –> Run, then type regedit and press Enter
Find a key called CheckedValue
Double Click “CheckedValue” key and modify it to “1“. This is to show all the hidden files.
