Wednesday is Windows 10 launch day. That means you should be able to upgrade your computer to Windows 10 — depending on the model and if you've been participating in the Windows 10 Insider program. It also means that retailers will begin selling the first Windows 10 machines, despite rumors that suggested new computers wouldn't be available right away. Staples on Tuesday revealed several machines that will be available from the website.

You'll be able to grab the Toshiba Satellite Fusion, a laptop that features a 5th-gen Intel Core i5 processor, a 15.6-inch display, and a 2-axis hinge, for just $699.99. Staples will also sell the Dell Redwood 2-in-1 laptop with an 11-inch display and a Pentium processor for $499.99, and the Toshiba Satellite S55 Core i7 laptop for $849.99.

Plenty of other retailers should have new machines available, too, and we'll let you know as we hear more. Staples said you can find these computers in stores in early August — they'll be available online only until then.
