So your manager just suggested that you upgrade all your machines from XP to windows 7, and upgrade office from 2003 to 2013? That's not necessarily kneejerk stupidity - did your manager include a list of benefits from upgrading, against a cost analysis, and allow for a test run of trying to run all your existing spreadsheets (presumably more complex than just a few numbers!) on the new system, or just say 'hey we should get a new version of everything we use, it won't cause any downtime' and the boss said like hell it won't? I think upgrading is probably a good idea, but it's definitely not a no-brainer 'ok do it tomorrow' idea.
