Msconfig.exe Stops Responding if User Is Not an Administrator

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.
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.
