Windows 7: Kaby Lake and Coffee Lake with Win 7

Kaby Lake and Coffee Lake with Win 7

Not sure what subforum this belongs so I'll ask here.

I'm thinking about getting a 7700k which is a Kaby Lake CPU. Is there anything I need to know in order to use that CPU in Win 7 other than the fact updates won't work without a hack? I don't care about updates since I really don't use them.

If you want to use igpu graphics, you need an particular driver, iirc. I have it somewhere if you need it.
Can't recall if that driver is for HD620 OR 630.

No, I always use dedicated graphics. I'll be using the hardware in my Specs. I just plan on changing the CPU with Windows still installed.

I do plan on upgrading the GPU some time as well in preparation for a HTC Vive for the Sim.

I'm using an i7 7700 myself with Win7 and as far as I know, Windows 7 with Kaby Lake has 3 main problems:

- Lack of integrated GPU drivers: Intel have agreed to help Microsoft to extorsion people into downgrading to Windows 10, and refused to provide drivers for any Kaby Lake and latter CPUs for anything earlier than Win10. Not tried with any external GPU, but as long as you have the proper driver you should be fine. Getting a working driver for the built-in GPU is possible, but difficult.
- Lack of built-in USB3 drivers: Exactly the same problem as with SkyLake, Windows 7 doesn't come with drivers for USB3 ports and those won't work. Installation could be trouble some, including the need to tamper with the installation disk (although there are ways to avoid doing so). Proper drivers are generally available and installing them isn't difficult, just getting Windows to run in the first place. Since you're upgrading only the CPU, it's unlikely that'll hit you.
- A malicious update blocks Windows Update until you downgrade to Windows 10: As you've noted this is a real thing with one of the "convenience rollups". Tampering with system files is necesary to continue to use updates, with questionable legal status. Since updates themselves are also questionable, it's unlikely that'll bother you.

Besides that, the only thing I can think of is any other missing driver for some other hardware, which in this case is not a problem since you already have the system up and running.

A secondary problem, not specific to any CPU is that a few software developers refuse to let their programs run on Win7 (mostly MS itself, surprise) for no good reason, but again since you're already running, no change is expected here.

I just setup a desktop last month with an i7-7700 and a Radeon R7 450. As Alejandro said, there are only three blocking issues, none of which are insurmountable. I did a clean install of Win7, but since it worked successfully I wouldn't expect you should have much, if any, trouble using an existing installation.

My Radeon driver came from AMD, but I also needed to install a HD630 driver to clear a yellow exclamation point in Dev Mgr. The HD630 and USB3 drivers came from Intel. I embedded them in the Win7 installation media via DISM command line instructions, but SIW2 has a little tool to do it via a GUI, as well.

The third problem, the Windows Update hack you mentioned, is not really a problem at all, IMHO. MS rolled out a KB patch to block Windows Update from running if it detected Win7 on a Kaby Lake system, but there's a third-party update (google "wufuc patch") that rolls back the MS kill switch. But even without the wufuc patch, it's only an issue if you want to continue using the Windows Update feature.

You probably know that MS updates now come in a couple different forms: either the cumulative monthly "you-get-everything" update, or alternatively the non-cumulative monthly "security only" updates. Windows Update only works with the former. You cannot use WU if you want only the "security only" updates. Those have to be downloaded separately, outside of WU.

Since I only want the "security only" updates, I have no use for WU, so the fact MS is blocking WU on Kaby Lake isn't relevant to me.

So like I mentioned, I have the computer already going with Windows 7 on a Skylake i5 6600k. I do have USB 3.0 drivers already installed. So that shouldn't be an issue with the 7700. Correct? The USB drivers are already installed and both CPUs are LGA 1151.

I haven't tried what you're doing, but that would be my assumption. It should be the same driver you already have, but in case it's not it should be easy enough to update it after the fact. The main problem with clean installs is the Setup routine can't even find it's own installation media if the USB3 driver isn't embedded in the boot media, but in your case that shouldn't be an issue.

ISTR SIW2 mentioning a USB3 problem with a couple of specific chipsets (H270? B270?), so you may want to review some of his earlier threads on the subject.

You might get a yellow bang in Dev Mgr for a missing HD630 driver, even with the Radeon drivers installed. If you do, you'll need to download the Intel driver from here. Scroll down to the 15.45.19.4678 version, as that's the last one that seems to readily support Win7 with the i7-7700. You'll still need to edit the igdlh64.inf file, but it's a simple edit. There are instructions in a couple other forum threads, as well as on YouTube.

Download the .zip version, extract the folder, and dump it somewhere on your system. Then go to the yellow bang in Dev Mgr, "Update driver", and point it at the driver folder you extracted.

GA-H270-GIGABYTE U.S.A.- vga driver for intel 7th gen windows 7

2.
USB ports won't work on Intel H370 , B360 and H310 (rev1) chipsets, the solution is to use an external pci controller ( PCI-E to USB 3.0 Expansion Card )

3.
Just released H310 (rev2) now available with win 7 drivers.

I don't have an AMD GPU or that motherboard. Please read my Specs and let me know if there will be any issues.

It is in answer to dg1261 and general information for others reading this thread.

Has anybody suggested you have an AMD gpu or that motherboard? The link is for 7th gen intel processors.
