I haven't even bought my SSD yet but I knew I would need drivers. Like everybody else, I landed here:
Update to add native driver support in NVM Express in Windows 7 and Windows Server 2008 R2 - Microsoft Support
Where they no longer provide the hotfix. My interpretation of what it says on that page is that they will give you the hotfix if you call them & pay them for it. Negatory.
In any case, I got the Nvme-Win7x64.zip since I'm running W7 64-bit. I installed the Windows6.1-KB2990941-v3-x64.msu no problem. Rebooted. Went to install Windows6.1-KB3087873-v2-x64.msu & it said it didn't apply to my computer. Reading between the lines of something you said above, I'm guessing that if you have SP1 installed, you needn't worry about this failure to install. Yes? No?
I see you have something for USB 3. I have USB 3 ports on this machine & I have used devices plugged into those ports. Now I'm wondering if I'm really getting USB 3 performance out of them. How would I tell? Maybe I'll just get that thing & try to install whatever it is. I've already booted today. My habit is to go at least a few weeks if not months between reboots. I hope you're not going to make me reboot AGAIN. Such a hardship . . .

Well, I did get your USB 3 package & looked inside it. That gave me the ID kb2864202. Searching the MS web site landed me here:
MS13-081: Description of the security update for USB drivers: October 8, 2013 - Microsoft Support
According to the information on that page & a couple of dir /s commands on my boot partition, I already have this particular fix on my system. I'm sure I installed it years ago when I was still letting Windows Update run all the time. I of course shut that off when MS decided to yank the rug out from under our feet & take W7 out of support. OK. That package wasn't what I thought it was. It is not something that adds USB 3 support to W7 the way your NVME package adds NVME support to the system. It's just a security update & it seems I already have it.
In a word, never mind.

Oh. And I'll be sure to come back here & give an update once I actually own an SSD & have tried to make it my new boot drive.
