Per this thread: USB 3.0/3.1 Drivers (original and modded) (111), as well as personal experimentation, it is indeed difficult to get "in box" pre-included Windows 10 drivers (or any drivers really) working on Windows 7. However, just ignoring this limitation for a minute, I do have some questions:

1. What are the full listings of both the NVMe driver names/files as well as the xHCI driver names/files? Aka, what .sys(es) and possibly .inf(s) are needed to have full functionality of generic NVMe and xHCI support under Windows 10 - and what are their names? (I know Windows 7 has a NVMe update/hotfix, but apparently the driver is old and does not write to the cache like it is supposed to on NVMe drives.)

2. Windows 7 also has (to my knowledge) in box drivers as well that do not have an associated .cat file. Might it be possible to "slipstream" the Windows 10 NVMe and xHCI drivers into Windows 7 in a similar fashion?

3. Could it be possible to create and sign your own .cat file for the drivers, and then just import the certificate into Windows 7 to make these drivers "work?"

No, this doesn't work, because the Windows OS Setup only accepts their own on-box drivers and not theones, which were extracted from another OS and are not digitally signed.

@Omicron:
The OS knows its own files (inclusive the drivers). Only "external" drivers need the digital signature, which is stored within the *.cat files.
