Add Specific Folders to the Open Dialog Box

When you use certain Windows applications (such as Notepad) to open a file, on the left side of the Open dialog box are a group of icons and folders (such as My Documents, My Recent Documents, Desktop, My Computer, and My Network) to which you can navigate to open files.
Good idea, bad implementation. Do you really keep documents in My Computer? Unlikely, at best. It would be much more helpful if you could list only those folders that you use, and if you could choose to put any folder there, not just ones XP decides you need.
In fact, you can do it, with a Registry hack. It'll let you put just the folders of your choosing on the left side of the Open dialog box. Note that when you do this, it will affect XP applications such as Notepad and Paint that use the Open and Save common dialog boxes. However, it won't affect Microsoft Office applications and other applications that don't use the common dialog boxes.
TIP: If you want to change the dialog "frequently used" folders for Microsoft Word, try Woody Leonhard's Place Bar Customizer, one of many useful utilities from http://www.wopr.com/.
Run the Registry Editor and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\comdlg32. This is the key that determines how common dialog boxes are handled. You're going to create a subkey that will create a customized location for the folders, and then give that subkey a series of values, each of which will define a folder location.
To start, create a new subkey underneath HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\comdlg32 called Placesbar, and create a String value for it named Place0. Give Place0 a value of the topmost folder that you want to appear on the Open dialog box-e.g., C:\Projects.
Next, create another String value for Placesbar called Place1. Give it a value of the second folder that you want to appear on the Open dialog box. You can put up to five icons on the Open dialog box, so create new String values up to Place4 and give them values as outlined in the previous steps. When you're done, exit the Registry. You won't have to reboot for the changes to take effect
If you want no folders to appear in common open dialog boxes, you can do that as well. In HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\comdlg32 create a new DWORD value called NoPlacesBar and give it a value of 1. Exit the Registry. If you want the folders back, either delete NoPlacesBar or give it a value of 0.
Turn Off System Beeps
To me, system beeps that my PC makes when it encounters certain system errors are like balloon tips-gnat-like annoyances that I can do without. So I turn them off using a Registry hack. Run the Registry Editor, go to HKEY_CURRENT_USER\Control Panel\Sound, and find the Beep and ExtendedSounds String values. Set each value to No. Exit the Registry and reboot. The beeps will no longer sound.
