My FurMark2 benchmark score using 552.55. https://www.gpumagick.com/scores/show.php?id=177863 Just like R545, Quadro GPUs users can use R550 by simple modification. However, NVIDIA app will replace control panel in near future. Unlike NVIDIA control panel, I think new NVIDIA app will not be compatible with 1607 anymore.

I thought driver security updates resulted in drastic FPS drop in P3R. But the true answer is UE4's shader compilation issue is the main reason. So I think I have to edit engine.ini carefully to deal with it.

Anyway, I don't think 1607 has any chance to run latest Blackwell GPUs, but only time can prove it.

My FurMark2 benchmark score using 545.84. https://www.gpumagick.com/scores/show.php?id=177195 NVIDIA added new codes to check Windows version during loading driver, so I modified the original requirement then 1607 can use R545 drivers, which means Quadro and Geforce Turing GPUs with NGX may use super resolution in latest VLC media player. For Quadro Turing users, the modification required for nvlddmkm.sys is quite simple. But R545 drivers no longer have security updates, so using R535 drivers should be better.

The minimum OS requirement of latest Intel audio driver 10.27.0.14 becomes 1809, so installing the driver on 1607 requires INF modification. Another problem is 24-bit audio output over HDMI may require Intel's control panel.

Windows 10 21h2 home edition reached EOS, but MS didn't block installation of CU by SSU or remove support for Core edition.

What I've told you has nothing to do with debugging, I can't teach you the answer you need because I am not a programmer. Instead I told you the solution I used, so you can run IDA and hex editor to modify the driver. Officially the minimum requirement of Quadro DCH driver is 17098. That is why 1803(17134) is required. But old minimum requirement in standard driver still works so Tuning GPUs still work on 1709 with DCH driver. If GeForce DCH driver requires 1803, I think 1803 should be enough for Ada Lovelace GPUs.

Did you make 3070 working with R510 and later? If you can't make 3070 and 4070 work by modification, I will guess NVIDIA uses different way to prevent GeForce from working on old version of Windows. Good luck.

Latest ME firmware 14.1.72.2287 broke the compatibility with Batman: Mask of the Phantasm UHD Blu-ray and resulted in noise and choppy playback at specific scenes. Although it is possible to downgrade the firmware on my ASUS ROG Strix Z490-F Gaming, it is still difficult to fix the issue because I can't find a simple solution. I tried using different sound card, reinstalling or updating audio driver or graphics driver, and none of them worked. Finally I solved the issue by switching off the power supply. Anyway, I think putting PAVP in the firmware which requires security update every year is a terrible idea.

OBS Studio 30.1.2 can do Vulkan game capture with FrameView enabled by using display capture instead of windows capture. But February security update of NVIDIA driver still resulted in performance hit when playing P3R.

It seems that latest dxvk 2.3.1 and Vulkan driver 1.3.280 from R550 solved the performance hit issue in P3R on Steam when I use 538.49. I also tried using 474.82 but R470 is not compatible with Vulkan 1.3 so replacing Vulkan driver didn't work on DX 12 games like P3R. Intel's graphics driver for 7th-10th Core processors also supports Vulkan 1.3. Unlike NVIDIA, Intel and AMD have 8 driver files related with Vulkan.

Intel released ME drivers 2413.5.67.0 to replace old 2141.15.0.2511. Latest Intel graphics driver 31.0.101.2127 results in blank screen with audio when I use PowerDVD 22.

Latest Nier: Automata on Steam offered two EXE files. One for old Windows without Windows HDR, the other one only works on Windows with Windows HDR. Without dxvk, the Windows HDR version only shows black screen with BGM. Although the Windows HDR version works with dxvk, Windows HDR can't be activated on 1607. Persona 5 Royal on Steam requires SetThreadDescription. Unfortunately the kernel32.dll of 1607 does not support the function and there is no utility like VxKex. So the game can't run on 1607 without modification.

R545 and later no longer work on 1607. I've tried modifying R545 and R550 by overwriting OS version in nvlddmkm.sys, but only got error code 37. Now I am using 538.49. Because 1607 is too old to support latest DX12, I can't start Persona 3 Reload on Steam. So I have to use vkd3d-proton 2.12 and dxvk 2.2 to start the game. However, I can access digital art book and OST without converting to Vulkan. I think the game crashed because 1607 does not support ray tracing. Besides, latest OBS Studio 30.1.2 no longer works on 1607 because obs.dll uses isWOW64process2 function instead of isWOW64process, so obs.dll can't work without modification.

Users of Realtek's HDA codecs have valuable experience, which helped me find my preferred solution. The true problem is ASUS can't provide reliable support quality for NUC 10. Only NUC 11 and later have new BIOS files.

Realtek's HDA codecs DCH driver for Windows 10 x64 requires version 1703 and later. But Microsoft update catalog offers 6.0.9239.1 for Vista x64 and later. The problem is Realtek only offers customized DCH driver, which means users have to modify driver if PC manufacturers no longer offer new audio driver for old motherboards. I need to modify two files. HDXxxx.inf for HDA audio driver, and HDX_xxx.inf in ExtRtk_xxxx folder for software component extension. It is better to install HDX_xxx.inf first before installing Realtek Audio Console, then I can install other software component like RealtekHSA and RealtekService. Finally, I have to install HDA audio driver so Realtek Audio Console can identify it. Because 1607 does not support extension of DCH driver, the 6.0.9239.1 driver from MUC is the only way to make PowerDVD 22 to play 24-bit LPCM audio. Anyway, SupremeFX S1220A (device id 1168) supports 24-bit audio on UHD Blu-ray.

Intel Graphics DCH drivers 31.0.101.2115 and later include AcxHdAudio related files which require 1903 and above. Besides, the iGPU of CML does not use AcxHdAudio. So MSHdaDac.inf must be removed from iigd_dch.inf before installation. To pass HDCP test with Lindy DP 1.2 to HDMI with HDR active converter in PowerDVD 22, I have to set LG 27GL850-B to DisplayPort instead of HDMI before PowerDVD 22 completes HDCP test. Then I can watch UHD Blu-ray at 4K23Hz with HDR over the monitor's HDMI. When TrueTheater HDR works, 4K23Hz becomes 4K60Hz. In 1607, the iGPU of CML decodes HEVC by DX9 DXVA. My motherboard does not support Blu-ray audio content protection, so PowerDVD downsamples the audio to 16bit 48kHz.

But latest Intel SGX driver, Management Engine driver, Wi-Fi and Wireless Bluetooth driver no longer work on 1607. Without INF modification, Intel 6th-10th Gen Graphics driver and Realtek HDA driver don't work on 1607. Of course LTSB 2016 still has monthly CU from Microsoft, but you can't solve security vulnerabilities without latest driver.

Starting with R530, the INF file of NVIDIA HDA driver no longer supports 32-bit version of Windows 10.

Intel no longer releases compatible driver for 1607 after 2022. NVIDIA dropped support for 1607 in 2023. So I think it is too late to use 1607 now. Besides, 1607 lacks complete support for DCH driver.

CyberLink and Corel decided to cease UHD Blu-ray playback features and corresponding online authentication in the latest version of PowerDVD 22, PowerDVD 365 and WinDVD UHD BD after October, 2023. https://www.cyberlink.com/support-center/faq/content?id=28347 https://kb.corel.com/en/129837 Bundled version of PowerDVD released after October 2023 also removed UHD Blu-ray playback features. https://jpn.pioneer/ja/pcperipherals/bdd/products/bdr-x13j-x/bundle/ PowerDVD 22 Ultra build 3214 is the last version to support UHD Blu-ray playback. But I want to make sure online SGX activation and the 1st initialization of the playback feature are still available, so I tried to install PowerDVD 22 Ultra build 3214 on my new PC in December 2023. Intel Core i5-10400 ASUS Rog Strix Z490-F Gaming BIOS 2801 (modified for SGX options required for Windows 10 x64 1607) Intel ME 14.1.70.2228v4 Chipset INF Utility (10.1.18793.8276) Intel Graphics DCH drivers (31.0.101.2111) Intel Network Adapter driver for Windows 10 (28.2) Intel Serial IO driver (30.100.2020.7) Intel Management Engine Interface driver (1937.14.0.1350, for DELL Vostro 3590) Intel SGX driver for Windows (2.15.100.4) The INF files of Intel Graphics DCH drivers and Intel Network Adapter driver require modification. Intel Management Engine Drivers 2141.15.0.2511 can not replace Dell's 1937.14.0.1350 because its INF files removes support for 10th Gen Intel Core processors including Comet Lake and Ice Lake. Intel stopped releasing non-DCH driver for Win 10 RS2 or earlier, so 1607 can not apply latest MEI and SGX patches. Besides, latest Intel Network Adapter driver 28.3 removes support for Windows 8. Intel ME 14.1.51.1528 results in choppy UHD Blu-ray playback with HDR over DisplayPort. Corel Ultra HD Blu-ray check tool 1.0.0.32 will stuck on SGX test, which means SGX is working. All offline tests passed after finishing online SGX activation and the 1st initialization of the UHDBD playback feature of PowerDVD 22. By using UEFITool, UEFITool NE and IFRExtractor to analyze Setup module in BIOS, I found that hidden SGX options like "Enabled" or "PRMRR Size" still exist. So I modified Setup module and AMITSESetupData module in BIOS, then I could enable SGX and set PRMRR size after running USB BIOS Flashback. The Q-Flash Plus on Gigabyte B560M D3H requires USB 3.0 flash drive. Although the USB BIOS Flashback on ASUS Rog Strix Z490-F Gaming is compatible with both USB 3.0 and USB 2.0 flash drive, the function usually hangs with solid green light, so turning off PSU switch before running USB BIOS Flashback is the only one solution. Anyway, I am sure online SGX activation and the 1st initialization are still available in December 2023, and PowerDVD 22 Ultra build 3214 can play UHD Blu-ray discs with HDR over Displayport or without HDR over HDMI 1.4. But I think online SGX activation and the 1st initialization service can't last forever. Besides, finding reliable DP to HDMI active converter cable with HDR is another problem. I bought Lindy DP 1.2 to HDMI with HDR active converter, but I only got 4k 30Hz available and HDCP 2.2 test by PowerDVD 22 failed.

It seems that CU has nothing to do with installation of Microsoft Edge. When I tried to get game patch files which contain microsoftedgewebview2setup.exe, the installation files of Microsoft Edge were downloaded.

Since October, the cumulative update of 21H2 will install Edge and ignore DoNotUpdateToEdgeWithChromium. So I have to uninstall Edge after Patch Tuesday.

Driver Release Branch 545 and later no longer support Version 1709 and earlier versions of Windows 10, so NVIDIA RTX and Quadro graphics cards will need INF modding. Besides, it seems that latest nvlddmkm.sys is still compatible with earlier versions of Windows 10.

I don't use hybrid shutdown or hibernating, and I didn't encounter the problem in Windows 10 21H2. But it seems that installing different NVIDIA driver is helpful in Windows 11 when GPU temperature disappears. https://forums.flightsimulator.com/t/gpu-temperature-suddenly-missing-in-windows-11-task-manager-performance-left-side/587896
