Finally, I modified nvlddmkm.sys to prevent the unloading process. It also needs to be test-signed. To prevent the drastic performance decrease, I disabled driver signature enforcement before installation. FurMark test result: http://www.ozone3d.net/gpudb/score.php?which=787187

When nvlddmkm.sys is loaded, it detects OS version. If I want to install 412.40, I need to replace 3839 with 3FAB, then nvlddmkm.sys will not be unloaded. The second problem is Windows 10 version 1607, because it has strict driver signing rules. https://techcommunity.microsoft.com/t5/Windows-Hardware-Certification/Driver-Signing-changes-in-Windows-10-version-1607/ba-p/364894 GTX Turing GPUs do not support NVIDIA NGX. Besides, I think NVIDIA blocks Pascal GPUs on 1507 by NvBlockTH1Install. USB 3.1 card based on Asmedia ASM1142 works on Windows 2000 with blackwingcat's extended core v16a installed.

I modified the INF file, and GeForce GTX 1660 Ti displayed Code 43 error on Windows 10 version 1607 Test Mode. GeForce RTX GPUs support Windows 7, 8, 8.1, and Windows 10 version 1709 or later. But Quadro RTX GPUs support 1607. Now I am sure the installation is not blocked by the INF file. The driver for NVIDIA USB Type-C Port Policy Controller can be found in PPC folder. I also checked the INF file in AMD Radeon software 19.7.1, and I think Radeon RX 5700 GPUs may support 1607.

It's a copy paste bot.

I think the wcp.dll you found in 14393.0 folder is a delta backup. It is not a complete file, so you can't find detailed information.

Just like KB4494440, KB4503267 also requires the same SSU. Apparently Education edition is blocked by wcp.dll. However, if you check update.mum in CU, you will find that Education edition is not completely blocked.

It is necessary to fix security vulnerabilities in nvlddmkm.sys, and make sure the driver works on Windows 7, 8.1, 10 (1507~1709). Besides, the release notes mention that NVIDIA display driver constrains Total Available Graphics memory to just below 4 GB for GeForce GPUs with 2.75 GB or less of video memory. .

NVIDIA released R390 U10 for 64-bit version of Windows. The release notes didn't mention support for 32-bit Windows, so I think this is the end.

Since kb4494440, kb4498947 replaces kb4132216.

AMD offers 32-bit version of Radeon Pro Software for Enterprise 18.Q4.1 which supports WDDM 2.4.

Nvidia released R390 U9. I edited nv_dispwi.inf and it works with GeForce GTX 960.

Because Radeon Software 18.10.1 does not support 32-bit Windows, 4gamer.net (a Japanese video game website) asked AMD, and AMD confirmed that Radeon Software support for x32-bit Windows operating systems has been moved to a legacy support mode. https://www.amd.com/en/support/kb/faq/pa-120 https://www.4gamer.net/games/022/G002212/20181018086/ The final Radeon Software for 32-bit Windows is 18.9.3. And Nvidia released R390 U8 at September 2018.

1607 reached end of service on April, so you can upgrade to different version. If your laptop has a Clover Trail processor, you can apply servicing stack update KB4132216 before installing cumulative update KB4467691. Besides, Microsoft released a security update KB4465659 for SSU.

Install KB4132216, then find the latest wcp.dll and change its ownership and permissions. Copy old wcp.dll to replace the latest one, then restore the ownership and permissions. I am using Windows 10 x86, so there is only one wcp.dll (x86) in KB4132216.

Official 1607 ISO file contains KB3199986 SSU, and it is compatible with KB4103720 and old Flash Player security update. Anyway, I solved the problem by replacing the latest wcp.dll with old one. The installation of KB4284833 is successful.
