There are so many brands and models covering a very wide range of capabilities and prices.
Are you looking for a laptop, all-in-one Windows PC similar to iMac, or "standard" PC? In a "standard" PC are you looking for a deskside tower, desktop chassis, compact system, or very small form factor system? Will you be using just Office Suite applications or will you want to do some AV/multimedia work? Games?
In a laptop, are you looking for low-cost commodity entry level models that typically weight a lot with an average typical 15" screen or are you looking for something more upscale? Do you want a 2-in-1, a light Ultrabook?
Windows 10 is pretty much standard these days but some will give you the option of a free Windows 7 "downgrade".
They all offer low-end, midrange, and premium products. If you want a laptop you can google search "best laptops 2017". Several articles from different sources will appear and you'll see a common thread for what's hot right now. Good luck.
