@m0nkrus:
Here is my comment:

1. Your test result statements are absolutely misleading, especially for users with an Intel NVMe SSD, who are searching within this thread for a suitable driver.
   A statement, whether a specific driver works or not, can only be given by someone, who has tested it on a system, where the related target device (here: "Intel NVMe Controller") is present within the test system.
2. Although I don't know the exact reason for the BSOD on certain test systems, it is very unlikely, that any of my INF file modifications was the origin of the BSOD. What I cannot exclude is the possibility, that the real Intel NVMe driver named IaNVMe.sys has been coded by Intel not to support the NVMe Controller DEV_FAF0, which is located within the "Intel(R) SSD 665p Series". This can only be verified by a user of such Intel NVMe SSD model.
3. Previously you had written, that the Intel NVMe drivers v4.3.0.1006 and v4.4.0.1003 as original and modded variants have been integrated into the Win7 ISO file. It was unclear for me, in which combination these drivers have been integrated into the Win7 ISO file. That is why I asked you to post the details about the integrated Intel NVMe drivers. As I understand you now, there have never been different Intel NVMe driver versions or variants integrated into the same ISO file. Is this correct?
4. On the other hand I do not understand why you have integrated so many different third party NVMe drivers into the Win7 ISO file, although the generic MS NVMe driver has been integrated as well and - contrary to the other ones - this MS driver definitively supports all available NVMe Controllers. This enhances the risk of an unwanted interference between different matching drivers and makes it more difficult for the Win7 Setup to decide, which one among the integrated NVMe drivers should be installed during the OS installation.

In my experience, the MS NVMe driver does not provide support for most of the NVMe devices I worked with.

@m0nkrus:
The specific drivers, which have been compiled by the manufacturer of the related device, work usually better than the generic drivers, which are offered by Microsoft. That is the only reason why I am offering mod+signed drivers for devices, which are natively not supported by the original third party drivers, but run fine with them, if the related HardwareIDs have been added into the INF file.
Users, who want to get Win7 clean installed, should be happy to get the OS running on the related system drive. For this purpose all problems with NVMe Controllers are solved, if the user integrates the MS NVMe Hotfix into the boot.wim and install.wim of the Win7 ISO file. Once the OS is running it is no problem to try another NVMe driver, if the user is not satisfied with the generic MS NVMe driver.

Welcome to the Win-RAID Forum!

Since I neither have a modern Intel chipset system (from 300-Series up) nor an Intel Optane SSD, I cannot answer your first 2 questions. If you should not get help from anyone else, I recommend to test the different drivers yourself.
By the way: All Intel RST drivers, which belong to the v16 or v17 platform, do support NVMe as well!

3) how do i install the certificate? before? after the driver? Import Win-RAID CA.cmd ? Win-RAID CA.cer ?

Welcome to the Win-RAID Forum!
Due to my recent experiences with an AMD X570 chipset mainboard I can confirm, what you have written: The installation of the mod+signed OFA NVMe driver may end with an unbootable system and this issue may not even be repairable the usual way.
That is why it is very important to set a "Restore Point" before starting the replacement of an in-box or WHQL certified storage driver by any other one.
If you should not be satisfied with the performance of the generic Microsoft resp. of the specific Western Digital NVMe driver, I recommend to try the installation of the original Samsung NVMe driver v3.2.0.1910. According to my recent tests the WHQL certified Samsung NVMe drivers are a very good choice even for non-Samsung NVMe SSDs. The installation has to be forced by hitting the "Have Disk" button, the compatibility warning can be disregarded, if you have set a "Restore Point".
Good luck!

Was anyone here fast enough to get the new Samsung NVMe drivers 3.3?
If so, it would be fantastic if you could post them here.
