I-94 Problem: You�re tired of looking at the same the dialup networking icon in the start menu and want to change it to a custom icon. The following registry entry lets you do so.

Hive: HKEY_LOCAL_MACHINE

Data Type: REG_EXPAND_SZ

The number 2 is the number of the icon in the file you want displayed. In this case, 2 specifies the third icon because the first icon in a file is numbered 0. If no number is used, the default is 0.

Hive: HKEY_CLASSES_ROOT
Key: LNKFILE
Value Name: IsShortcut

Restart your machine for these new values to take effect.

I-104 Problem: You have a machine that different people use at different times. You have recently had complaints that people can see what others were working on and that it is a potential security problem. You can manually remove these file entries, but this registry modification automatically deletes the files for you. Modify the following value under User Shell Folders.

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\Policies\
Explorer\User Shell Folders
Value Name: Recent
Data Type: REG_DWORD
Value: C:\Recycle

Set your recycle bin to automatically delete files. Log off and then log back on. Now the Document menu option always reads empty.

I-105 Problem: The Explorer interface seems a little slow on some of the older computers in your installation. Here is a neat little trick to turn off animated or so-called �exploding� windows. Add the following value under the explorer key:

Hive: HKEY_CURRENT_USER
Key: Control Panel\Desktop\WindowsMetrics
Value Name: MinAnimate
Data Type: REG_DWORD
Value: 0

I-106 Problem: When you select an option from the Start menu and that menu option has multiple options, a window displays the additional menu selections � but sometimes these additional menus seem slow or delayed. You can really speed things up with the following registry modification. The lower the number, the faster the menus are displayed. The default value on my system was 400. Change the following value under the Desktop key.

Hive: HKEY_CURRENT_USER
Key: Control Panel\Desktop
Value Name: MenuShowDelay
Data Type: REG_SZ
Value: 1

Now choose the Programs option from the Start menu. The submenus are displayed instantly! No delay.

I-107 Problem: You want to restrict access to network drives and local drives from the Explorer interface. This registry modification lets you do just that. To disable all drives, add the following value under the Explorer key:

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\
Policies\Explorer
Value Name: NoDrives
Data Type: REG_DWORD
Value: 03FFFFFF

This value is a bit field, where each bit corresponds to a letter in the alphabet, as shown below.


   0    3    F    F    F    F    F    F
0000 0011 1111 1111 1111 1111 1111 1111
       zy xwvu tsrq ponm lkji hgfe dcba
If the bit is on (value of 1), access to the drive from Explorer is disabled. If the bit is off (value of 0), access to the drive is enabled. To disable everything but the A, B, C, and D drives, just set this value to 03FFFFF0:


   0    3    F    F    F    F    F    0
0000 0011 1111 1111 1111 1111 1111 0000
       zy xwvu tsrq ponm lkji hgfe dcba
You must log off for these new values to take effect. Note that this change does not disable access to the drives; it just disables their appearance in the Explorer interface.

I-108 Problem: You have a corporate standard for the way users are supposed to configure their systems. Yet you have a pesky user � you know the one � who knows enough to mess up everything, but not quite enough to fix it.

Hive: HKEY_CURRENT_USER

Restart your machine for these new values to take effect.

Value Name: NoRun
Data Type: REG_DWORD
Value: 1

Restart your machine for these new values to take effect.

I-110 Problem: Users continually clutter their desktops with icons, then they can�t figure out what they�ve done and you have to come fix it. This registry entry lets you hide all icons on the desktop. That way users can run programs only from their respective program groups. Add the following value under the explorer key:

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\
Policies\Explorer
Value Name: NoDesktop
Data Type: REG_DWORD
Value: 1

Restart your machine for these new values to take effect.

I-111 Problem: You want to keep users from using the Find command in the Start menu. This registry entry lets you disable the Find command. Add the following value under the explorer key:

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\
Policies\Explorer
Value Name: NoFind
Data Type: REG_DWORD
Value: 1

Restart your machine for these new values to take effect.

I-112 Problem: Windows NT selects the location of default folders in the following manner. Each user has a default location where Windows NT stores files � for example, the Favorites folder. This folder points to a directory stored in the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ex plorer\Shell Folders key. The default value is %USERPROFILE%\. For example, Favorites would be stored under %USERPROFILE%\Favorites. You can change the value in any of the thirteen keys to reflect a different directory than the default value.
