            · Speed up scrolling by Pressing and holding 
            the Ctrl key while you scroll.
            · To expand all the subfolders of a selected 
            drive in Windows Explorer, press the asterisk (*) key on the numeric 
            keypad (this could take a while if the directory has lots of folders 
            in it). But watch out-there's no easy way to collapse them again.
            · To restore the default column widths in 
            the Details view of any folder window and many program or applet windows, 
            press Ctrl and the plus sign (+) key on the numeric 
            keypad.
            · Win9x has trouble retaining default folder and 
            Explorer window settings-such as size, position, sort order, toolbar 
            status and display type (large icons, details and so on). Here's a 
            temporary workaround. Open the folder for your C:drive, and without 
            opening any other folders, arrange and configure it exactly as you'd 
            like all your folders to appear. When you're ready to set the default, 
            press Ctrl+Alt+Shift while you click the close box 
            in the upper right-hand corner of the window. There's a limit to the 
            number of specific folder instances Win9x can remember, so eventually 
            your setting may roll off the list. Repeat the steps to restore your 
            settings
            · Find out exactly what a program does when you install it 
            by using the System File Checker's log feature. After installing program, 
            open the log by launching the System Information utility (Start/Programs/Accessories/System 
            Tools/System Information), choosing System File Checker from the Tools 
            menu, clicking on the Settings button and then on the View Log button. 
            The log will tell you exactly which files were added to your computer 
            and which were updated with a newer version.
            · Take any .BMP file, rename it to give it an .ICO 
            extension, and voila! Instant icon. You access the file in the normal 
            way: Right-click on the current icon for a shortcut, select Properties 
            from the Context menu, select the Shortcut tab and click on the Change 
            Icon button. Now use the Browse button to find your new one. I use 
            the paint program to do this to create favicons for Web sites.
            · Win98 comes with a handy way to check your Registry for errors. 
            Launch the Microsoft System Information (MSI) utility from Start/Accessories/System 
            Tools/System Information, then select the Registry Checker from the 
            Tools menu.
            · Insert the current time and date in Notepad by pressing 
            F5. Or, if you want to log the date and time automatically 
            each time you open a Notepad file, type .LOG on the first line, then 
            save and close the file. Every time you open the file thereafter, 
            the current date and time will be recorded in it.
            · To manage the active window, press [Alt][Spacebar]. 
            Then press the appropriate hot key to select Restore, Move, Size,

            · Get with detailed columns - Windows Explorer 
            gives a customizable view of the files and folders on your computer 
            or network. By default, when you highlight a folder in the left pane, 
            you view the files and subfolders in the right pane. But these views 
            can be customized by Detail, List, Large Icons, or Small Icons views 
            using the Views menu.
            · RESCUE YOUR WINDOWS PRODUCT KEY If you ever have to reinstall 
            Windows 9x from a CD, one of the worst problems you can face is to 
            find that you no longer have the original CD case and its Product 
            Key. Without the Product Key, you may find that you cannot reinstall 
            Windows. However, because you were asked for the Key when you first 
            installed Windows, it's saved in the registry. This means that you 
            can locate it before removing Windows from your system. Even if you 
            are unable to start Windows, as long as you can get to the command 
            line, you can run this on the System.dat file that's part of the registry. 
            At a command prompt, type one of the following commands (depending 
            on which version of Windows you are working with):
            · For Windows 95 installations, type: 
          FIND.EXE/I 
            "ProductId" %winbootdir%\SYSTEM.DAT
          The 
            %winbootdir% should look up the folder in which Windows is
            installed; however, it can only do this if the system environment 
            variable is set.
            If you've had to boot the computer from a floppy, then it might not 
            be
            set. In that case, you should "cd" into the folder where 
            System.dat is
            located and run the command from there.
          For 
            Windows 98 installations, type:
          FIND.EXE/I 
            "ProductKey" %winbootdir%\SYSTEM.DAT
          The 
            first line of the values returned should show the product key in a
            form similar to ?????-?????-?????-?????-?????.
          If 
            you select the Details view, you get Name, Size, Type, and Modified 
            columns with details on each file and folder. Each column is resizable 
            for information viewing preferences. It's also possible to (on purpose 
            or by accident) drag each of the column width markers to the left 
            edge of the pane--effectively making them disappear.
          Once 
            created, there is a way out of this blind view. Click in the empty 
            right-hand pane and simultaneously press [Ctrl] and the plus sign 
            (+)from the keyboard's 
            numeric keypad. This sets the column widths back to the default minimum 
            width.
          In 
            addition, you can fix the problem over a Win 9x client network if 
            you have remote access to users registries. Locate the 
            HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer 
            
          key, 
            and delete the DirectoryColsX subkey. This will automatically 
            · reset the column widths on the next startup of Explorer.
