Installed a NVMe SSD, but Win7 doesn't detect it.  

So, just got myself a brand new WD-Black SN750 1TB NVMe Internal Gaming SSD - Gen3 PCIe, M.2 2280, 3D NAND - WDS100T3X0C on my PC. It fit the MoBo perfectly, and the Bios detects it OK. However, Win7 won't detect it as there doesn't seem to be a driver available.

I've been checking around, and I've heard mention of KB2990941; a hotfix Microsoft released to fix this. However, they've removed said hotfix from official websites to "encourage" people to upgrade to Win10, so I'm now trying to find that hotfix, as well as finding out if it comes with some kind of caveat or problem; I've heard from a few places it can cause your PC to start showing a 7E error.

So, does anyone knows where to find it? And once I have it, what can I do to avoid that 7E error? Thanks in advance.

what can I do to avoid that 7E error.

Install both KB2990941-v3 and KB3087873-v2

Sweet! And I had just found out about KB3087873 and how it fixed the problems. Lemme try this out...

EDIT: Yup! Worked like a charm, and with seemingly no strings attached. Had to manually assign it a letter on Disk Manager, but that was no big deal. Thanks for the help.

No disk manufacturer has a failure rate anywhere near that.

The implication was there. There isn't any reliable evidence that one manufacturer is more reliable than another for any given type of disk.

Your own experience is anecdotal.
