Taskbar

Table 5-14 describes the settings in the Taskbar category. Most notably, you can disable balloon tips by setting the REG_DWORD value EnableBallonTips to 0x00. Create this value if it doesn't already exist.

Grouping

The settings in the Grouping category, as described in Table 5-15, enable you to control how buttons group on the taskbar. Using the TaskbarGroupSize value, which you create if it doesn't already exist, you determine the applications that Windows XP collapses into groups first:

  • Group least used applications first. Windows XP groups least frequently used applications first, and groups more frequently used applications as necessary.
  • Group applications with the most windows first. Windows XP groups applications that have the most open windows first, and groups applications with fewer open windows only as necessary.
  • Group any application with at least N windows. Windows XP groups applications that have N windows open on the desktop.

Windows XP uses the same REG_DWORD value for all three cases. If you set TaskbarGroupSize to 0x00, Windows XP uses least-used grouping. If you set it to 0x01, Windows XP uses most-windows grouping. Finally, if you set it to any other value, Windows XP groups any application that has that number of open windows.

XP Start Menu

Windows XP displays the most frequently used programs on the bottom of the Start menu. This handy feature prevents you from having to hunt for applications you use often. Some applications don't belong on this list, however. I tire of seeing Notepad on the Start menu just because I happened to use it to view a text file. I also don't like seeing Command Prompt on the Start menu every time I type cmd in the Run dialog box. The solution is to tell Windows XP which applications you don't want it to add to the Start menu. Do that in the key HKCU\Software\Classes\Applications.

In Table 5-16, look up the application that you want to keep off the Start menu's list of frequently used programs. If you don't find the program in Table 5-16, find the program's file name by looking in the Program Files folder or at the program's shortcut on the Start menu. Then add a subkey to Applications, in which the name of the subkey is the program's file name (omit the path). Add the REG_SZ value NoStartPage to the program's subkey, and leave it blank. For example, to keep Notepad off the Start menu, create the subkey Notepad.exe in HKCU\Software\Classes\Applications, and add the value NoStartPage.

Desktop

One of the most popular customizations for Windows 98 was to remove the icons from the desktop. That meant users did not display the My Documents icon and the Network Neighborhood icon. Windows XP caught up with users' tastes and displays only the Recycle Bin icon on the desktop by default.

If you miss the good old days, you can add the icons back to the desktop. Use the Tweak UI category Desktop. Table 5-17 describes the values corresponding to each icon. Add each value to the subkey NewStartPanel, creating it if it doesn't exist, and set it to 0x00 to hide the icon or 0x01 to display the icon.

First Icon

Using the First Icon category, choose the icon that you want to appear first on the desktop: My Documents or My Computer. Table 5-18 describes the settings you need to apply for either scenario.

Drives

Windows XP can hide drive letters. You hide them by setting NoDrives in the key HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, but it's easier using the Tweak UI category Drives. The trick is figuring out the value to put in the REG_BINARY value NoDrives.

Each bit in NoDrives, right to left, corresponds to the drive letters A through Z. To hide drive A, turn on the first bit. To hide drive B, turn on the second bit. Turn on the bit representing each drive that you want to hide. This math is easier if you use Calculator in Scientific mode. Also, see Chapter 1, "Learning the Basics," for some tips on doing bitwise math.

Special Folders

Windows XP users have special folders in their user profiles, such as the My Documents, My Pictures, and Favorites folders. The default location for these folders is in %USERPROFILE%, but you can redirect them to any location, including a location on the network. That's the purpose of the Tweak UI category Special Folders.

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders is the key where you find each of these special folders. You learn about them in detail in Chapter 4, "Hacking the Registry," and Chapter 17, "Per-User Settings." In Table 5-20 on the next page, look up the folder you want to redirect. Then in User Shell Folders, change the value shown in the Value Column to the folder's new location. I suggest that you use environment variables, particularly when referencing folders in %USERPROFILE% or %SYSTEMROOT%. The next time you log on to Windows XP, Windows XP updates HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\ to reflect your changes. After relocating a shell folder, you must manually move your files and folders from the old location to the new location.

AutoPlay

All the action in the AutoPlay category is in its subcategories: Drives, Types, and Handlers. In the Drives category, you can prevent specific drives from playing media automatically when you insert them. You use the value NoDriveAutoRun, which is a REG_BINARY value, just like the NoDrives value you learned about earlier. For each drive that you want to stop from playing disks automatically, set the bit, right to left, which corresponds to the drive letters A through Z. NoDriveAutoRun is in the key HKCU\Software\Microsoft\Windows \CurrentVersion\Policies\Explorer.

The next subcategory is Types. In this category, you can control whether CDs, DVDs, and removable drives automatically play when you insert disks. Table 5-21 describes the values that correlate to the settings you see in this category. Just like you did with the value UserPreferencesMask, you must toggle the bit shown in the Data column. To prevent CD drives from automatically playing, for example, set bit 0x20 in the REG_DWORD value NoDriveTypeAutoRun.

Table 5-21 Values in Autoplay Drive Types

Enable Autoplay for CD and DVD drivesNoDriveTypeAutoRunREG_DWORDBit 0x20
Enable Autoplay for removable drivesNoDriveTypeAutoRunREG_DWORDBit 0x04

The last subcategory is Handlers. When Windows XP detects that you've inserted a CD, DVD, or removable disk, it automatically runs the program that it associates with the type of content on that disk. You control what programs are used with which types of content using the Handlers tab. This setting is much easier to configure in Tweak UI than manually, but we'll try it anyway.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AutoplayHandlers \EventHandlers is the key where you find these associations. In Table 5-22, look up the type of content you want to customize. Then open the subkey shown in the Subkey column for EventHandlers. In that subkey, add any of the following handlers as an empty REG_SZ value:

  • MSCDBurningOnArrival
  • MSOpenFolder
  • MSPlayCDAudioOnArrival
  • MSPlayDVDMovieOnArrival
  • MSPlayMediaOnArrival

Control Panel

The Control Panel category enables you to hide specific icons in Control Panel. Create a REG_SZ value in the key HKCU\Control Panel\don't load, and name it using the file name of the CPL file you want to hide. Set the value to Yes to display the icon or No to hide the icon. Table 5-23 shows the file names of the CPL files that come with Windows XP. For example, to hide the Internet Options icon, add the REG_SZ value Inetcpl.cpl to don't load, and set its value to No.

Templates

Use the Templates category to customize the templates you see when you right-click the desktop or the unused space in a folder window, and then click New. Chapter 4, "Hacking the Registry," and Appendix A, "File Associations," describe how to build customized templates. Table 5-24 describes the values that Tweak UI uses for each of the default templates in Windows XP. Note that if you disable any of the templates shown in Table 5-24, Tweak UI hides the ShellNew key by renaming it to ShellNew- (adds a dash).

Search

This is my favorite customization. The Tweak UI's category Search enables you to add search URLs to Internet Explorer so that you can use search engines from the browser's address bar. For example, add the prefix news and set its URL to http://groups.google.com /groups?q=%s&hl=en; then you can quickly search Google Groups for Windows XP by typing news Windows XP in the address bar. Figure 5-4 shows a search URL.

Figure 5-4 You don't need to download any search add-ins for Internet Explorer when using your favorite search engines is this easy.

Add the subkey SearchURL to HKCU\Software\Microsoft\Internet Explorer. Then add a subkey for each search prefix you want to use. To use the example I just gave you, create the subkey news. Set the default value of the prefix's subkey, news in this example, to the URL of the search engine. Use the %s as a placeholder for the search string. Internet Explorer replaces the %s with any text you type to the right of the prefix. Continuing the Google Groups example, you'd set the default value to http://groups.google.com /groups?q=%s&hl=en.

Add the REG_SZ values shown in Table 5-26 to the prefix key you created. The purpose of these values is to describe what to substitute for special characters in your search string, including a space, percent sign (%), ampersand (&), and plus sign (+). These characters have special meaning when submitting forms to Web sites, so you must substitute a plus sign for a space, for example, or %26 for an ampersand. Thus, the browser translates the search string Windows XP Bits & Pieces to Windows+XP+Bits+%26+Pieces.

The only question left now is where to get the URL. That's easy. Open the search engine you want to add to Internet Explorer's search URLs, and then search for something— anything. When the browser displays the results, copy the URL from the Address bar, replacing your search word with a %s. For example, when searching Google Groups for honeycutt, the results are in a Web page with the URL http://groups.google.com /groups?q=honeycutt&hl=en. Replace the search word honeycutt with a %s to get http://groups.google.com/groups?q=%s&hl=en.

View Source

Use the View Source category in Tweak UI to change the program in which Internet Explorer displays a Web page's source. Set the default value of the key HKLM\SOFTWARE\Microsoft \Internet Explorer\View Source Editor\Editor Name to the path and file name of the program you want to use. Create this value if it doesn't already exist.

Command Prompt

If you're a command-line junkie like me, you'll appreciate file name and directory completion. The MS-DOS command prompt supports both of these features, but you have to enable them first. Table 5-27 describes the settings in the Command Prompt category in Tweak UI. Set the value CompletionChar to the keystroke you want to use for file name completion, and set the value PathCompletionChar to the keystroke you want to use for directory completion. You can use the same keystroke for both values. The value you use for key is the ASCII key code. Thus, Tab is 0x09. The value WordDelimiters is a string of characters that delimit words on the command line when you press Ctrl+Right Arrow or Ctrl+Left Arrow. Create these values if they don't exist.

Logon

In the Logon category, you toggle Autoexec.bat parsing by setting the REG_SZ value ParseAutoexec in the key HKCU\Software\Microsoft\Windows NT\CurrentVersion \Winlogon to 0 or 1. Set ParseAutoexec to 0 to prevent Windows XP from parsing Autoexec.bat for environment variables. Otherwise, set ParseAutoexec to 1, and Windows XP will parse it for environment variables.

Autologon

The last useful category in Tweak UI is Autologon, and it enables you to automatically log on to Windows XP without providing your name, domain, or password. Table 5-27 describes the values you must set to log on to the computer automatically. Name is the user name, and Domain is the domain name. To enable Autologon, you must set the REG_SZ value AutoAdminLogon to 1. Last, set the value REG_SZ value DefaultPassword in the subkey Winlogon to the password you want to use to automatically log on to the computer. You don't see this value in Tweak UI because it stores the password differently.
