Not sure if this is the right section but oh well.
Basically I upgraded to windows 10, but I did a fresh install, so all my apps are gone which is fine, until I forgot I vitally needed Microsoft Office. I have a backup, but I don't want to literally do a backup, my computer was already slow, that's why I fresh installed. Basically I just want to recover my Microsoft office, is this possible? Cheers in advance
Your biggest problem wll be the Product Key to activate any new installation you make. If you don't have that, you're dead in the water.
However, Libre Office is a highable workable equivalent and will open documents, spreadsheets, Publisher projects and Powerpoint presentations. If you used Outlook, Mozilla Thunderbird will import your e-mail and contact data and run with it. It's Opensource and as such is free but they welcome donations.
To "recover" Office (or any other licensed app), you need two things: Installation media, and activation key. You can restore back your backup, use application like Belarc Advisor, and recover your activation key, but you need installation media compatible with that key (eg. Home, Professional, etc).
