There are hardware considerations so you might want to look into it. Also, you should have installed Lubuntu. The L is for Laptop, I don't know what specifically is different but it could matter. I don't need to run 50 different office programs when LibreOffice does it all. For free. I also like that the updating is when I choose, what I choose and no anti-virus needed. If I bought something with Windows on it, it would disappear fast.
As long as you aren't doing things professionally, Libre works pretty decently. But it isn't office, not by a long shot. I'm finishing up my doctoral thesis, and I sure wouldn't try to do that with Libre. For one thing I am part of a team, and the collaboration tools are vital, as are the OLE features to Project, Visio, and Excel.
Anyway, on the same hardware, Windows 10 performs better. This has Vivid Vervet, because Ubuntu releases new versions constantly.
Since IOS is the #1 target of viruses and malware, the old nonsense of Windows being more vulnerable is dead. Android (Linux) is the #2 target. The reason these two OS's get hit so often is simple, they are the biggest.
Linux is not inherently safe, it just was traditionally too small to bother with. Oh, and some of those Android viruses are being set loose on Linux desktops, so don't get caught by your false sense of security.
