When you start your Compaq computer after you upgrade Internet Explorer, you may receive one of the following error messages:
Explorer: This program has performed an illegal operation and will be shut down.
If you click Details, the following error message is displayed:
Explorer caused an Invalid Page Fault in module Shell32.dll
Cpqshell caused an invalid page fault in module Kernel32.dll


This issue can occur if the [Boot] section of the System.ini file contains the following line:
NOTE: The Cpqshell.exe file is incompatible with the Shell32.dll file that is included in Internet Explorer.


To resolve the issue, change the Shell= line in the System.ini file to Shell=explorer.exe. To do this, use the following steps:
  1. Click Start, point to Programs, point to Accessories, and then click Notepad.
  2. On the File menu, click Open.
  3. In the File name box, type c:\windows\system.ini, and then click Open.
  4. Click Search, and then click Find.
  5. In the Find what box, type shell=, and then click Find Next.
  6. Type a semi-colon (;) at the beginning of the Shell= line, and then create a new line.
  7. On the new line, type shell=explorer.exe, click Save on the File menu.
  8. Restart your computer. Click No if you receive the following prompt:
    Your system shell has changed. The Compaq software will work with your new shell, but the new shell will not work with your Compaq software. Do you want to keep your Compaq software working?
