I've been using Focusrite Scarlet 2i2 1st gen for 5 years. Compatible with Windows 7, 10 and I believe with Mac(although I've no experience with Mac).
Interface usually comes with a free DAW (recording software) and other free plug ins.
I have no experience with any other interface but I can't fault focusrite 2i2. Recorded in excess of 40 of my own songs from punk, rock, metal, acoustics, electronic, some pop. It's a reliable and quality built product.
Do your research first as there are lots of great products and each may come with extra DAW etc.
As for DAW I occasionally use Audacity to slow diwn songs or devide left and right channel.
I tried free version of Reaper but dudnt like it.
As dad3353 said there is a thread on subject.
