I bought a new Lenovo ideapad 530s-14ikb laptop computer. It has Windows 10 64 bit OS, but I would like to use windows 8.1 64 bit OS, and I installed Windows 8.1 myself.

I can not find the driver for Intel(R) UHD graphics 620. There is only driver for windows 10. How can I solve this problem? Thank you.

The only way to solve the problem is to run Windows 10. There are no drivers for anything less than Windows 10.

Al is correct; only Windows 10 is supported on the 8th generation processors. There are no device drivers for Windows 8.1 other than a few that overlap.
