Starting with v5.5.2.1, the ITE Tech CIR driver pack removes old drivers so it is no longer compatible with 1607.

If your desktop computer supports NVMe M.2 SSD, you don't need dual channel memory.

Starting with 22.160.0, the Wi-Fi driver for AX201 no longer works in 1607. I've tried 22.160.0 and 22.170.0, but Device Manager reported error code 39.

OS and driver are different, so the solution will be different.

Just use WinDbg.

Unlike 20 series and 16 series, you've proved that 30 series require version 1803 instead of 1709. By starting kernel mode debugging, you can find the hex value and create your solution.

You have to debug the graphics driver and find out your answer. All I can say is that it is not as difficult as you think.

If you want to install DCH driver on 1709, just modify the INF file.

If you can debug graphics driver, it is possible to solve the problem by modifying the driver. However, updating Windows to version 1709 or later is a better solution. https://msfn.org/board/topic/179590-nvidia-geforce-rtx-error-code-43-on-windows-10-version-1607/

Intel SGX PSW 2.16.100.3 removes support for RS2 and before, so 2.15.100.4 is the last release that supports 1607. Besides, Intel Management Engine Drivers 2141.15.0.2511 is the last release that supports 1607, because 2216.16.0.2805 also removes support for RS2 and before. Therefore, Intel Lunar Lake processors only support PAVP on RS3 and above. Intel SGX Driver for Windows v2.15.100.4 https://www.intel.com/content/www/us/en/download/683952/intel-software-guard-extensions-intel-sgx-driver-and-data-center-attestation-primitives-intel-sgx-dcap.html Intel Management Engine Drivers v2141.15.0.2511 https://www.intel.com/content/www/us/en/download/682431/682437/intel-management-engine-drivers-for-windows-10-and-windows-11.html Bluetooth driver 22.130.0 and 22.140.0 trigger error code 37 on 1607. Fortunately, new Intel Graphics drivers such as 30.0.101.1191 fixed DirectX 12 support issue on 1607, but it seems that 30.0.101.1340 and 30.0.101.1404 have refresh rate and audio problems with PowerDVD 20.

If you can't install any CU on 21H2, you should try to find out the incompatible driver or hardware. If you can install old CU on 21H2, but you can't install KB5013942 because it rolls back, you can try KB5015020, which replaces KB5013942.

KB5013624 is not CU. Did you install any CU successfully on 21H2 before installing KB5013952? When WU is stuck at specific percentage, it will be helpful if you can describe the installation percentage. If you are using incompatible driver or hardware, you may install the OS, but WU will fail with rollback.

Did you try installing KB5015020 instead of CU KB5013942?

I updated to 512.78. The DCH display driver package contains NVIDIA Control Panel application. To launch DCH version of NVIDIA Control Panel for the first time, Internet connection is required, and WU, Windows License Manager Service, and Microsoft Account Sign-in Assistant should be enabled. I don't know how to install standard NVIDIA Control Panel and Container along with DCH display driver. The standard NVIDIA Control Panel is still compatible with DCH driver, so users of non-DCH driver can launch standard NVIDIA Control Panel from Windows Control Panel.

Starting from R495, NVIDIA no longer provides non-DCH drivers. The minimum version supported is 1607.
