Customization Tricks For Windows XP

Use registry shortcuts to disable and enable screensavers in Win XP:The steps in this tip will show you how to edit the registry for a time-saving shortcut for enabling and disabling your screensaver.When you perform maintenance operations such as defragmenting or backing up the hard disk, you probably disable your screensaver before you begin to prevent it from interfering with the maintenance operation. However, disabling your screensaver manually is a multistep operation that involves accessing the Display Properties dialog box, navigating to the Screen Saver tab, and setting the screen saver to None. Then, you need to re-enable the screen saver after you complete the maintenance operation.Fortunately, you can automate the disabling and enabling screen saver procedures with a couple of registry shortcuts. Note: Editing the registry is risky, so make sure you have a verified backup before making any changes.Here's how.1. Launch Notepad and type the following four lines. (Note: Th...

Create the a Dword value and name it "ProtectionMode "4. Set the Value to 1The Fix For Grayed Out Boxes:The File Types tab in Explorer's View / Options menu lets you edit most of your file types, but certain settings cannot be changed. The default action for a batch file, for instance, runs the batch file instead of opening it via Notepad or Wordpad. Thus, when you double-click on AUTOEXEC.BAT, a DOS window opens, and the file executes. If you want to change this default action and edit a batch file when you double-click on it, however, the File Types tab does not let you do so; the Set Default button for the file type called MS-DOS Batch File is always grayed out.The button is grayed out because HKEY_CLASSES_ROOT's batfile key contains an EditFlag value entry.

Add Open With to all files:You can add "Open With..." to the Right click context menu of all files.This is great for when you have several programs you want to open the same file types with.
