Off topic ramble...
I've started to realise I no longer use Office products, either Microsoft or OpenOffice etc. When my kids were at school I bought a famiy pack of 3 licences for one version (2007?) which I get hassles from Microsoft these days when trying to activate - have to say it's not installed elsewhere even though logically and legally/contractually it can be as a 3-licence deal. Whatever, we don't use it anyway, I just hate the idea of having something that doesn't work for bureaucratic reasons. I have 2010 with the physical media and key, and then 2013 and 2016 - maybe 2011 too - as downloadable river/whatever items that always seem a hassle to reinstall (or even obtain media for).
All of that hassle with Office makes me distrustful of Microsoft, though against that I've never had an issue with Windows activation that couldn't ultimately be resolved. Haven't tried activating XP lately, because I'm down to one "retro PC" that runs 98 and my other is mothballed (though from the hardware that'll be 98 too). I wonder whether at this point there's any need for XP - I'm not sure there's much I'd want to play that wouldn't work on 98 or 2000. Black and White maybe, I never got round to that; though I'm pretty sure it ran on 2000.
