The free OSR Learning Library has more than 50 articles on a wide variety of topics about writing and debugging device drivers and Minifilters. From introductory level to advanced. All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

I'm preparing a driver to support Windows 11 (I'm using Windows 11 22000 as a test machine). The driver is listed as File System and Windows Filtering Platform.
For now all tests are passed except one - AppContainers_Tests (only Traffic test variation 10 is failed). This test is always failed with Traffic was unexpectedly blocked error. Even if the driver does nothing (I modified the driver and its DriverEntry just returns STATUS_SUCCESS without any other actions) the test is failed.
I tried to disable the built-in firewall during this test, but it is still failed. Also I run this test on built-in drivers mpsdrv.sys and wdnisdrv.sys - this test is failed for built-in drivers too.
I tried to upgrade my test machine to Windows 11 22449, but HLK wan't able to recognize it, so I can't say if the issue is fixed after upgrading.
In this test variation a client uses TCP address fe80::1:0:0:FE to connect to a server with InternetClient capabilities. In the next variation a client uses the same address with InternetClientServer capabilities, and this test is passed. So I suppose IPv6 is working.
Have anyone encountered this issue? Is there a way to safely ignore this test to pass certification?
