You can fetch MSCONFIG from your XP cd or from this link:
http://www.spywareinfo.com/~merijn/winfiles.html

BE AWARE AND READ THE NOTICE on the link:

"Several variants of the CoolWebSearch trojan are overwriting Windows system files with copies of the trojan itself, reinstalling it whenever this infected file is called by Windows.

CWShredder detects and removes these infected copies. You can download the files replaced by the trojan here, if the version for your Windows version is available. Note that these are all for US-English Windows versions.

If the file is not available for your Windows version, you can always restore it from your Windows Setup CD!

A mirror of the files on this page is available at: OfficeFive.org.uk

Note: The files available for download on this page are taken from US English versions of Windows (unless noted otherwise). If you have a Windows version in any other language, you should not use these files."

As to the DVD item, 4.7 Billion Bytes seems to be 4.4 GB. It's a common problem.
