    I have installed Virtual PC 2007 in Windows Vista Business running as the
    host and Windows XP SP2 running as the guest. Everything seem to run fine
    until an update for MSXML 4.0 SP2 is needed to be installed in Windows XP SP2
    that somehow keeps repeating whenever I shut-down the guest OS. Similarly the
    patch for MSXML 4.0 SP2 keeps appearing whenever I go to Windows Update site
    even though a previous installation has already been successful.

    Are you using the "Undo disk" feature and discarding changes maybe?

  3. I've seen the same thing on my XP VPC running on XP (SP2 for both). This is
    after saving the changes, too.

    I managed to resolve the issue that I reported earlier which in fact has
    nothing to do with Virtual PC 2007. Rather, this is a known issue with the
    security update for both KB927978 (
    and KB925672 ( This
    issue is also widely discussed in MSDN forum
    However, there is a workaround to resolve the problem while waiting for
    Microsoft to release a fix. Below are the steps to rectify the issue.

    Step 1.) Uninstall both MSXML 4.0 SP2 (KB925672) and MSXML 4.0 SP2
    (KB927978) from the Add/Remove Programs located in the Control Panel.
    Step 2.) Reinstall both updates using Windows Update site.
    Step 3.) (OPTIONAL) Delete all alphanumerics folders which contain only a
    reported log file created during the installation of both updates previously.

    Thanks & Regards,
