Before you create the master image, there is a series of tasks you need to perform to prepare and optimize the reference computer:

Note: Unless otherwise noted, the tasks in this section apply to Windows 2000/XP

as well as Windows Vista.

1 If the reference computer already has an OS and applications installed on it (as may be the case when receiving a new computer directly from the

manufacturer), use a tool such as GDisk to wipe the hard disk’s MBR or to perform a full disk wipe.

2 Perform a clean installation of Windows on the reference computer using a volume license. Do not add the reference computer to a domain.

CAUTION If the machine is a member of a domain when Sysprep runs, then

when you deploy the master image to the users’ computers, Sysprep will not be able to automatically add the users’ computers to a domain. Therefore, always make sure the machine you are using to create the master image is not a member of a domain when you run Sysprep.

3 Install Windows service packs, patches, and updates as needed.

4 The drivers for the following devices often prevent the reinstallation of Plug and Play devices, so you must remove them from Device Manager:

– Network cards – Modems – USB hubs – Audio

– Keyboard and mouse (Important: Do not reboot after uninstalling these drivers, even if you are prompted to do so.)

– Video (Important: Uninstall this driver last. Also, do not reboot after uninstalling the video driver, even if you are prompted to do so.)

5 If any null drivers are present in Device Manager, remove them.

Null drivers prevent Windows from reinstalling their related devices during the next reboot. These drivers appear as yellow icons in Device Manager.

To remove a null driver, right-click the device and select Uninstall.

6 Windows XP: Configure the Default User profile to comply with corporate standards (for example, set wallpaper and screensavers to the corporate standards, add corporate documents to the Documents folder, and so on). By doing this, any user profile that is added to the computer in the future will be automatically configured to comply with corporate standards.

To configure the Default User profile in Windows XP:

a Create a temporary administrative user.

b Log in as the temporary user and configure system settings as needed.

c Log off the temporary user and log in as Administrator.

d Run the User Profiles management tool (Control Panel —> System —> Advanced tab —> User Profiles group box —> Settings) and copy the temporary user’s profile settings to the Default User profile.

Note: In some cases, you may need to reboot the computer before you can

perform the copy operation.

e Delete the temporary user profile.

7 Install any additional applications that you want to include in your base image. Include an application if at least 80 percent of your users need it. Also, install important application patches. Do not install applications that are hardware- related (Control Panel items, hardware utilities, and so on).

8 Often, hardware-related applications are installed by default during an operating system installation to provide extra functionality for such devices as video, network, mouse/touchpad, and so on. Open the Control Panel, double- click Add/Remove Programs, and uninstall any applications that are hardware- related.

7 9 Remove any unwanted or unneeded files from the C: drive, including files in

temporary directories.

10 Clear out cached Internet Explorer documents, including Files, History, and Cookies.

11 Run a defrag utility.

12 Set the system paging file to zero, as follows:

a Right-click on My Computer and select Properties.

b Windows XP: Click the Advanced tab.

Windows Vista: Click “Advanced system settings.”

c In the Performance group box, click Settings.

d Click the Advanced tab.

e In the Virtual memory group box, click Change.

f Select the option “No paging file” and click Set.

Note: In Windows Vista, you must remove the check mark from the

“Automatically manage paging file size for all drives” option before you can select the “No paging file” option.

g In each of the open dialog boxes, click OK until you are back at the desktop.

h Reboot the computer.

13 From a command prompt, run CHKDSK /F C:

CHKDSK searches for and fixes any disk-related errors that could affect the integrity of your image file. To run CHKDSK on the system drive, you must reboot your computer after running the CHKDSK /F C: command.

14 Configure Windows to rebuild the pagefile based on the destination workstations’ total memory.

a Run REGEDIT.EXE.

b Delete the existing multi-string entry for:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ Session Manager\Memory Management\PagingFiles c Create a new string value for:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\

Session Manager\Memory Management\PagingFiles=C:\pagefile.sys 0 0 15 Windows XP: You may want to change how the Guest login account is used.

By default, Windows XP forces anyone attempting to connect to a remote system to log in as “Guest.” To allow the connecting user to enter a name and password instead of having to log in as “Guest,” perform the following:

a Run REGEDIT.EXE. b Locate the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Forceguest c Change the “Forceguest” value to 0.
