Windows 7 drivers for Intel Wireless AC-9260  

why nvidia - is there an internal nvida card? It would be best if you posted the entire machine specs here. Or a link to the download page for all of the win10 drivers (that would go on the machine if you were going to run win10). Not just two or three lines of specs. Lots of details. Buying a laptop that is made to run win10 and then loading win7 onto it is not a simple task

Respectfully, no, you have not posted your specs. You have posted your model number, cpu and memory amount. Here are an example of specs. They are for a Clevo-N850HP6. I googled your machine and got this one. Its not your machine, its just an example of specs.

I suggest you start a new thread called "I'm buying a laptop not available in the US, it has Win10 on it and I want to put Win7 on it". Then right at the start of the post, put your detailed specs. Why?

Because there are 5 or even 10 challenges when loading win7 onto a laptop designed for win10. We can't help you address those challenges without knowing the exact model numbers of the mainboard, video card, wireless card, cd-drive, usb drive version number, storage devices, etc. Every single line in the specs above has hardware that is running a Win10 driver, and when you load Win7 onto the machine you will need to make sure that every single line has a Win7 driver that will work. This is a problem because new hardware often will not have any older drivers. So without this detail, the folks here can't tell you if what you are doing is feasible.

the driver above is not specifically for a laptop, its just the intel beta driver for kaby lake graphics (intel cpu models that start with a 7, like 7700 or 7500). The driver will work on any win7 laptop or win7 desktop with a kaby lake cpu. Its the intel driver version 21.20.16.4508. Below is a thread about this, including links to the same driver on other sites. Most motherboard manufacturer sites have a copy of the driver for download, if you google 21.20.16.4508 you'll get a lot of hits.

HD Graphics 630 and Windows 7 : intel

can you recreate the below on your computer and post a screenshot? Here's how

1) start>run>devmgmt.msc
2) left click on the triangles to the left of disk drives, display adapters, network adapters, and usb controllers, to expand them. (network adapters may already be expanded)
3) right click on the wireless adapter, select properties, then details, then hardware ids, then move the window so its aligned like mine is below so you can take a screenshot

here is a link on how to post a screenshot if you need it
