SYMPTOMS

When you try to apply changes in the Msconfig.exe tool, Msconfig.exe may stop responding (hang). However, an administrator may be able to complete the same operation without any problems.

CAUSE

This problem can occur if you do not have sufficient permissions to make the change in the Msconfig.exe tool. Msconfig.exe still tries to save the changes even if you do not have the appropriate permissions, and then retries this process after it receives an access denied error.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
