  1. 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.
  2. 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.
  3. Starting with R530, the INF file of NVIDIA HDA driver no longer supports 32-bit version of Windows 10.
  4. 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.
  5. 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.
  6. 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.
  7. Since October, the cumulative update of 21H2 will install Edge and ignore DoNotUpdateToEdgeWithChromium. So I have to uninstall Edge after Patch Tuesday.
  8. 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.
  9. 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
  10. KB5000812 is the final security update for 1703 on Surface Hub, and MS released it on March 9, 2021. But you still can get other updates from WU.
  11. You can check the end of servicing dates first. https://learn.microsoft.com/en-us/windows/release-health/release-information
  12. I don't understand why 21H2 ISO file offers incomplete Japanese IME. Anyway, the Japanese IME in 1607 ISO is compatible with version 21H2. Unlike version 1607, I can't stop BITS and WU from re-enabling by using Microsoft Management Console.
  13. Latest CU KB5023697 removes support for Home edition, so it's time to upgrade to a newer version of Windows.
  14. Intel Xeon E 2300 series processors support SGX with SPS, but SPS does not provide PAVP. Tiger Lake-B desktop processors may support SGX with ME, but BIOS files for 500 series chipsets do not support SGX. Besides, ME firmware 15.0.10 and later removed iCLS and tcb. So Intel NUC 11 Extreme can't support UHDBD playback.
  15. Starting with v5.5.2.1, the ITE Tech CIR driver pack removes old drivers so it is no longer compatible with 1607.
