However, I tested it myself and have not run into any problems. By following my instructions, you must understand that the result might be unpredictable in your case. Thank you for understanding, let's begin.

Hello, everyone! So, what's the issue?

You can easily download and install Windows 7 drivers of NVIDIA graphics cards (up to 3090 ti, 40 series and above are not supported). However, only with their regular (desktop) versions, not laptop ("notebook"). So, how can you install the driver?

1. Get your device id. Go to Device Manager, find Standard VGA Adapter, select properties -> Details -> Hardware ID. You need to take the longest text value of all the present ones.
2. Download a Windows 7 driver for the regular version of you graphics card from nvidia.com. In my case its version is 473.81, higher version may not work for some reason. However, it doesn't really matter because the latest Game Ready release is from 2021, so gaming experience isn't going to change.
3. Unpack the installer using 7-Zip, go to the Display.Driver folder and open nvaci.inf. Then, find this line:

[NVIDIA_Devices.NTamd64.6.1]

and replace Device ID in the following line (keep "Section001, ") with the line you copied from Device Manager earlier, so you have something like this:

%NVIDIA_DEV.1341.0867.1025% = Section001, PCI\VEN_10DE&DEV_1F15&SUBSYS_3A4717AA&REV_A1

Now you need to save the file and run setup.exe from the unpacked folder. Windows'll likely ask you if you really want to install that driver, you need to approve that.

It actually works! Seems like drivers for different versions (desktop and laptop) of a graphics card are practically the same. By the way, you can also edit 6.2 and 6.3 sections to make it compatible with Windows 8 and 8.1 respectively.

I really hope my tutorial was useful, good luck!
