Have you noticed? The number of test items in Windows HLK 24H2 has decreased compared to 23H2.
Today, I just installed the 24H2 version of the HLK and was preparing to give it a try. I noticed that for the same test target, the 24H2 version only has a few (less than 5) test tabs (playlist not loaded), whereas the 23H2 version has more than 60. I'm not sure what updates have caused this, can anyone help explain?
hardware dashboard
Hellow. I want submit .hlkx files with tests results from HLK Studio through web pages on https://partner.microsoft.com/en-us/dashboard/home. I created a free tenant with Global Admin rights on the Azure portal. I added the Hardware program. Since then, an error has been reported when trying to connect to this program - Page not found. When i test web page https://partner.microsoft.com/en-us/dashboard/Registration/Tenant/Hardware?step=GetStarted?step=GetStarted# - Reported error 404 Resource not found. I found sample program HardwareApiCSharpSample on microsoft web pages. It was created only token with it and for create Product (for files hlkx submission) the same problem - Reported errr 404 Resource not found. I dont known where is problem and what way send the hlkx files to certificate program portal. Can you help me.
Bluetooth device connection problems
We have built a HID/MIDI multifunction device and are having connection problems only on Windows (works on iOS, Mac, Android). It only happens on some Windows PCs. I think it happening because Windows rejects several connection parameter requests and then terminates the connection, but I don't know why it is doing that. I've attached a packet capture from BTVS. You can see in frame 297 a connection parameter update request is rejected, and then in frame 299 the host sends a disconnect. Could you confirm this is what is happening, help me understand why Windows is terminating the connection, and what we can do about it? Thanks https://we.tl/t-ebJMwwYZkcThe same version, different driver date driver update problem
Hi、technical advisor I would like to confirm whether the driver date has a higher priority than the driver version when updating the driver through windows update. For example: I have a driver, the version is 2.0.0.354, the driver date is 2021/10/22, because the test found that there is a problem with this driver, the manufacturer changed the inf file and re-passed WHQL, and the driver version is still 2.0.0.354, It's just that the driver date has changed to 2021/10/25, I released a new driver through WU, it was a critical release, and I checked "Automatically delivered during Windows Upgrades" and "Automatically delivered to all applicable systems", this new driver Will it be downloaded and installed automatically? Will the new driver be automatically downloaded and installed for devices that have activated the Windows operating system, while the new drivers will only be downloaded and not automatically installed for devices that have not been activated for OEM testing?thank you very much!
HLK test case fail //DF - PNP Rebalance Fail Restart Device Test (Development and Integration)
HLK Test case : "DF - PNP Rebalance Fail Restart Device Test (Development and Integration)" is getting failed with the error WDTF_PNP : ERROR : PNP.RestartDevice() Win32=1 - Incorrect function. We are performing this test on Windows server 2016 VM without any other test software. (We are not installing our driver or software). The test case is falling all the times on clean VMs. I could see the similar test failing with same error in Regression test case. (DF - PNP Rebalance Fail Restart Device Test (Regression)). After applying the latest filter, Regression test is getting passed but Development and Integration test is still failing. Does anyone see this issue and How can I proceed further.
Guidance needed on submitting motion sensor tests for certification of sensor hub as an IHV
My group is an IHV specializing in inertial motion sensor processing. We're working on an Windows 10 sensor hub driver for 2-in-1 laptop systems and would like to get certified. We've set up our HLK system, and have read the “Integrating Motion and Orientation Sensors With Windows 10” doc and the https://docs.microsoft.com/en-us/windows-hardware/test/hlk/testref/how-to-run-hck-motion-sensor-tests guide online. It looks like the test results are handled manually via the SensorInfo app. How would we bundle our results given the manual nature? And is true that for our purposes, we’d only need to run the 5 sensor-specific tests (ie. Accel, Gyro, Inclinometer, Compass, and Orientation)? Any help would be greatly appreciated.UEFI GOP mode
Hello: About UEFI GOP mode test Topology Selection: • UEFI must reliably detect all the displays that are connected to the POST adapter. The Pre-OS screen can only be displayed on a display connected to the POST adapter. •In case multiple displays are detected, UEFI must display the Pre-OS screen based on the following logic: System with an Integrated display(Laptop, All In One, Tablet): UEFI must display the Pre-OS screen only on the integrated display If the laptop system Pre-OS screen is also displayed on the external monitor simultaneously, will this violate the regulations?SysVAD Virtual Audio Driver Sample updated

Changes to the Windows 10 Update experience were announced today by Mike Fortin, Corporate Vice President, Windows. These changes, introduced with the Windows 10 May 2019 Update, will put customers more in control of updates to their systems. Highlights include: Improving user choice, quality and transparency Increased focus on user feedback, including a longer release preview phase. Users will be in control of feature updates. Microsoft will only automatically initiate a new feature update if the installed version of Windows 10 is nearing the end of support (for security updates). New features for user control of updates New “check for updates” functionality allows users to clearly know when they are initiating quality or feature updates. Users of Windows 10 Home Edition will now have the option to pause updates (both feature and monthly) up to a total of 35 days (7 days at a time) when a quality or feature update is offered. Intelligent Active Hours to avoid disruptive reboots. Expanded focus on quality More time in the Release Preview phase, with additional ecosystem partner interaction for added early-feedback. Improved early detection and resolution of low-volume, but high-severity issues. Public dashboard for increased issue transparency New dashboard communicating issues, update status and messaging.
