A Windows Server 2003-based computer may repeatedly restart after you uninstall hotfix 842642

A Microsoft Windows Server 2003-based computer may repeatedly restart after you uninstall hotfix 842642.

This problem may occur if the following conditions occur in the order that they are listed:

1.	You install security update 891711 on the computer.
2.	You install hotfix 842642 on the computer.
3.	You uninstall hotfix 842642.

This problem occurs because the Update.exe utility and the Spuninst.exe utility create the same temporary file name for the Winlogon.exe file and the Win32k.sys file.

Note The Update.exe utility and the Spuninst.exe utility are used to install and to remove Windows service packs and some hotfixes.

Note This problem may occur with packages that include a version Update.exe that is earlier than the 6.1.022.4 version.

To resolve this problem, either install a service pack or apply a hotfix. After you install the service pack or apply the hotfix, you must modify the registry to enable the fix. For more information, see the "More Information" section.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Use hotfix 897703 instead of hotfix 842642 to fix a problem. If you already installed hotfix 842642, do not uninstall the hotfix.

If you install Windows Server 2003 Service Pack 1 or hotfix 897703, you must modify the registry to enable the fix. However, if you have already installed the 842642 hotfix and followed the instructions in that article to add the SupportLinkedFontConTextOut registry entry, you do not have to complete the following procedure.

To enable the fix, use one of the following methods:

Method 1. Modify the registry directly

To modify the registry directly, follow these steps:

1.	Click Start, click Run, type regedit in the Open box, and then click OK.

5.	Right-click SupportLinkedFontConTextOut, and then click Modify.
6.	In the Value data box, type 1, and then click OK.
7.	Quit Registry Editor.
8.	Restart the computer.

Method 2. Import the registry entry from a file

To import the registry entry from a file, follow these steps:

1.	Start the Notepad program. To do this, click Start, click Run, type notepad.exe in the Open box, and then click OK.
2.	Copy the following data, and then paste the data into Notepad: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize] "SupportLinkedConTextOut"=dword:00000001
3.	On the File menu, click Save As.
4.	Choose a location to save the file, and then type a descriptive name in the File name box. For example, type GRE_Initialize.reg as the file name. Note When you save the file, you must use a .reg extension.
5.	In the Save as type list, click All Files.
6.	In the Encoding list, click Unicode.
7.	Click Save.
8.	Quit Notepad.
9.	Double-click the .reg file that you saved in step 7. This action adds the registry entry.
