Office 2013 seems to have appeared on my computer, alongside Office 2007 that I own. I never bought Office 2013, I never downloaded it, I have no idea where it came from. When I clicked on it out of curiosity it downloaded Excel 2013 then asked me to sign in with the account my subscription is associated with. I've now uninstalled it.
What's going on here? Did Microsoft slip it onto my PC with windows update, hoping it would get my to buy it or something?
