DOCUMENT:Q194965 10-AUG-2001 [winnt] TITLE :Desktop Update Lost by Running Windows NT 4.0 SP4 Uninstall PRODUCT :Microsoft Windows NT PROD/VER:WinNT:4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 SP4 - Microsoft Windows NT Server version 4.0 SP4 - Microsoft Windows NT Server, Enterprise Edition version 4.0 SP4 ------------------------------------------------------------------------------- SYMPTOMS ======== The desktop update and the Internet Explorer icon will be lost after running the uninstall for Windows NT 4.0 Service Pack 4 (SP4) if the Internet Explorer 4.x Browser was installed previous to applying SP4 as browser only, and the desktop update was not installed until after SP4. CAUSE ===== The Service Pack 4 installation creates an uninstall folder by default that will contain the current system files including Shell32.dll and Explorer.exe. When the Internet Explorer desktop update is installed, it will replace these files but will not update the files in the SP4 uninstall folder. If SP4 is uninstalled, the files that were on the system when SP4 was installed will be restored. RESOLUTION ========== To work around this problem, reapply the desktop update: 1. In Control Panel, double-click Add/Remove Programs. 2. Select Microsoft Internet Explorer 4.0 and click Add/Remove. 3. Select Add the Windows Desktop Update Component from Web Site. MORE INFORMATION ================ This will be an issue with any software installed after Service Pack 4 that replaces Windows NT system files. ====================================================================== Keywords : Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400search kbWinNT400search kbWinNTW400sp4 kbWinNTSsearch kbWinNTSEntSearch kbWinNTSEnt400sp4 kbWinNTS400sp4 kbWinNTS400search Version : WinNT:4.0 Issue type : kbbug ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
