This HP Pavilion a767c has Windows 10, 64-bit, installed and is already ACTIVATED.
This one has a H-IG41-uATX motherboard.
It comes with the complete Microsoft Office Suite: Word, Excel, Access, PowerPoint, Outlook, FrontPage, and Publisher.
Glary Utilities shows it boots up in about 19 seconds.
This is mainly due to the SSD (Solid State Drive). It's only a 120 GB drive but it does the job. Notice it is divided into two partitions, C and E. There is also a regular 1 TB hard drive (drive F) attached for you to store all your files.
Though I was able to install Windows 10, 64-bit, onto this computer, it has only a Pentium Dual-Core CPU E5700 running at 3 GHz and only 4 GB of RAM. From all I can tell, the 4 GB of RAM is the absolute max you can upgrade this to. So, if you are a multi-tasker with a computer on Windows 10, you'll find that sometimes it won't keep up with you. Just sometimes, and only when you're multi-tasking.
It does have a wi-fi card installed. However, take a close look at the pics where I show the back of the case. This is an older wi-fi card which uses a wire antenna. It's still really good at receiving and sending, but it could be a little awkward for you to string this antenna wire up.
The DVD/CD player works great for you to watch movies and listen to your jams.
All those USB ports work great.
If you need a monitor, keyboard and mouse to go with this, I have that for an additional $30.
If you live in Bella Vista, I can deliver this to you at no additional charge.
