    [Sung to the tune of an old blues standard]

    My notebook was running the..Release Candidate
    Since early in springtime, and all was just great
    When final release code, was shipped to my door
    I left it alone there, sayin’ I don’t need no more

    The programs were runnin’, the data was hot
    The widgets so useful, I had such a lot
    So no need to install, the RTM disc
    When everythin’s alright, then why take a risk?

    (Chorus):

    But oh, oh, oh, tell me it ain’t so
    I got the Windows 7 Outlook crashing blues (yeah yeah)

    Twas only last Monday, started out strong
    But purty soon I noticed something was wrong
    Cause every few minutes, my Outlook would crash
    And then it would restart, with full memory cache

    There’s no way of workin’, you cannot progress
    When crashes are reg’lar, much to your distress
    I tried to reboot it, I started to fuss
    But nothing could stop this, not even a cuss

    (Repeat Chorus)

    So now I’m alone here, the reformat starts
    The first stage of install, in so many parts
    And finally farewell to Release Candidate
    Hello to release code, you’d better be great

    (Final Chorus)

    Cause oh, oh, oh if you ain’t good
    I’ll have the Windows 7 Outlook crashing blues forever more.

    [Since determined that part of the problem is the Office 2003 junk mail filter that Windows Update insists on installing unless you switch it off. Hope that helps those who get with the same problem.]
