You can use the registry parameter to redirect the source of root certificate updates: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\AutoUpdate "RootDirURL"="d:\......." Is it possible to automatically distribute certificates of intermediate certification authorities in this way?104Views0likes0CommentsACPI EC OpRegion location
Hello, the ACPI specification defines OpRegions for ACPI bytecode to interact with devices, one suche device being the Embedded Controller. After looking at some example ACPI tables, it seems that Embedded Controller OpRegions can be defined anywhere inside the ACPI namespace, and not just inside the Embeeded Controller device scope. What is the Windows kernel policy for such OpRegions? Which Embedded Controller will be used to handle them (if any)?

Hi, We recently purchased an EV certificate to sign our software kernel driver, however, when trying to load it in Windows 10 it fails with code 0x800B010C aka CERT_E_REVOKED - A certificate was explicitly revoked by its issuer. We checked the driver with "signtool verify /v /all /pa" as suggested by our cert provider and everything is still valid. We followed these instructions https://docs.microsoft.com/en-us/windows-hardware/drivers/dashboard/attestation-signing-a-kernel-driver-for-public-release We've also tried contacting Microsoft's dev support by MS closed it down recently and they're not replying anymore... Any help would be appreciated, A.2.1KViews1like3CommentsHow to open a url in Edge WebView2 control within mmc instead of old Internet explorer?
Can we replace old IWebBrowser2 with IWebView2 controls in mmc so that websites open using new Edge WebView2 instead of old internet Explorer. I want the website to open within mmc and not outside in a popup new window. Is there any code that I can refer to achieve this? Or any change in registry settings to help achieve this? Note: I tried the webview2 in win32 apps in c++ sample code provided on Microsoft's website which opens webview2 component in a new window. But that when I tried to integrate the same with mmc snapin it did not work.814Views0likes0Comments
