I am using Office 2007
I tried the office 365, but it kept locking up when offline and it came with a Win8 tablet i bought awhile ago. I didn't care for it. And i don't use all the features that it provides anyway, so it a waste of money. When I went to see what MS Office you had now, it was rename MS 365, then on top of that its a monthly or yearly subscription, which I hate as well. There was MS office2019 student, but again, for what i used, a big price tag.
So the features I do use mainly Word and Excel, I never needed to upgrade to newer version, which again, waste of money. I rarely use Power Point, never used Access or Outlook
I would have stuck to even older versions but they kept forcing the upgrade notification.
When the update popped up, i checked to see what it was. There a lot of complaints in how it interferes with opening documents and excel and I am like "don't need that aggravation". So i asked if MS ever fixed those issue. And of course, since MS don't support it any longer, why am i getting an update.
In any case, power went out today, and as the PC rebooted, those updates installed. Now if it gives any issues I am looking at ways to uninstall it, if that needs arises.
