6. Change the IP Address of the Wireless Hosted Network

A new feature in Windows 7 and Windows Server 2008 R2 lets you create a virtual Wi-Fi router, called a Wireless Hosted Network. By default, Windows assigns this virtual interface the IP address of 192.168.137.1. However, you can change this address in Windows Registry.

Change the "ScopeAddress", "ScopeAddressBackup", and "StandaloneDHCPAddress" DWORD values at the following location:

HKEY_LOCAL_MACHINE\SYSTEMCurrentControlSetservicesSharedAccessParameters

7. Remove the Public Folder Shortcuts

If you don't use the Public folders provided by Windows, you may want to remove the shortcuts in XP or Vista. You find them on most open/save file dialogs and in the Favorite Links section of Windows Explorer windows. A shortcut is even on the main folder list, among the shortcuts to the user folder and to the drives.

These shortcuts do not appear in Windows 7. However, the Public folders are by default chosen as a location for the Libraries, which you might want to change.

To remove the shortcut from the Favorite Links in XP or Vista, open your Links folder (C:Usersyour_user_nameLinks) and delete Public.lnk.

To remove the shortcut from the Folders List, you must delete the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion

explorerDesktopNameSpace{4336a54d-038b-4685-ab02-99bb52d3fb8b}

8. Remove the Shortcuts to the Shared Documents Folder

If you don't want users to use the Shared Documents folder in Windows XP, you might want to hide the shortcuts to it. Just create the "NoSharedDocuments" DWORD value and set to "1" at the following location:

HKEY_CURRENT_USERSoftware\MicrosoftWindowsCurrentVersionPoliciesExplorer

9. Change the Default IP Address of ICS

As you may know, Windows includes a very useful feature called Internet Connection Sharing (ICS) that lets you share your Internet connection. Windows gives the virtual router the IP address of 192.168.0.1 and hands out addresses via DHCP to computers. This however is the default IP of popular off-the-shelf routers like D-Link. Therefore, you might want to change the default to something else to avoid an IP conflict.

To change the IP address of ICS, modify the "ScopeAddress", "ScopeAddressBackup", and "StandaloneDhcpAddress" DWORD values at the following registry location:

HKEY_LOCAL_MACHINESYSTEMControlSetServicesSharedAccessParameters

10. Remove the Hand From Icons of Shared Resources

By default, Windows adds an image of a hand to all the icons of shared folders and printers. This makes it easy to distinguish resources that are being shared on the network. Sometimes you might not want this. Luckily, there's a quick registry hack to remove the hands.

Change the "Default" REG_SZ value from "ntshrui.dll" to blank at the following location:

HKEY_CLASSES_ROOTNetworkSharingHandler
