I have AMD Radeon HD 6500m/5600/5700 Series installed on an HP Pavilion dv7 Windows 7 laptop, and it can't be updated to be used in Windows 10. Do you have a help option?
According to the official information on the website, the drivers for this laptop might be available through Windows Update. This means that if you configure the laptop to connect to the Internet, Windows Update will scan it and provide all the drivers necessary, because there is no download on the Support page if you choose Windows 10 as the operating system.
However, you can simply download the driver for Windows 7 and then you can install it normally in Windows 10 because it will work. Run the drivers in compatibility mode and everything should be just fine. You only need the network one and Windows will do the rest.
