Since I basically said that it was not possible, I should update my findings, in case anyone else has a need for this.
Both of the following driver packages work. I saw comments on-line about them before I posted my last comments here, but I didn't believe them, since if both Intel & Microsoft say it is not going to work, then what's the average guy posting on the internet know about it?
I should also say that while I did not test this, it is my understanding that if you have a dedicated graphics card, then it takes over, and a person should not have any problems. It is with the integrated graphics that the issue arises.
I had not tried this driver from MSI, because it was a beta test version. But it works, while the final version does not. Crazy, huh?
intel_vga_kbl_w7.zip is the beta version from the MSI site on B150M Pro-VDH, version 21.20.16.4508.
The other is from a non-MSI site. Its full name there is Intel HD & Iris Graphics Drivers Version 21.20.16.4526 WHQL.

Since the latter is a later version number, it might be best, since the MSI one is a beta, but the manufacturer’s own drivers might be best for other reasons.
I tested both, and they render the same results in the Windows Experience Index. (Showing some slight improvements in the graphics ratings over the 6th gen Skylake i3-6100 3.7 GHz CPU. This is, incidentally, the area of the bottom scores for both.)
System description: Windows 7 64-bit SP1 (no internet updates) on MSI B150M Pro-VDH with the i3-7100 3.9 GHz Kaby Lake 7th gen CPU, Seagate 7200 RPM 1 TB HDD, 8 GB Kinston HyperX DDR4 2133 MHz RAM.
Add'n'l Note: You do also need to create a modified Windows installation disk in order to install Win 7 on a 100 series chipset MB. Otherwise, the USB functions disappear after you get out of the BIOS. Also, while no one said anything about this on-line that I saw, in my experience even a PS2 mouse & keyboard will cease to respond, and you simply cannot go on with the installation.
