A problem has been discovered in the Microsoft Windows XP Pro update procedure. Users may expect that previously installed patches will carry over when they upgrade to Windows XP Pro from an earlier Microsoft operating system (such as Windows 98). However, it has been reported that previously installed patches for Internet Explorer 6.0 do not carry over when the upgrade is undertaken. Users may not be aware that they are running an unpatched version of Internet Explorer 6.0. To complicate matters further, the previously installed patches are not available via the Windows Update service for XP Pro and must be sought out by the user. This issue is known to affect upgrades to Windows XP Pro where the browser was a patched version of Internet Explorer 6.0. It is not known whether this affects other patched versions of Internet Explorer, or upgrades to other versions of the Microsoft operating system (such as Windows XP Home).
