Upgrade to windows 10 from windows 8.1?

What programmes and apps do i delete to make more space on my laptop. When I tried to download and install windows 10 upgrade I got a message saying more space was needed. I got the laptop as a present it is a Lenovo yoga 300

Did you upgrade the laptop first or did you download or upload large files then upgraded to windows 10?

You can delete anything you don't want.
Start with videos. Then games. Then photos. Then documents.
