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.

Have any of you seen this gem yet?
If I read this correctly, and it's not entirely clear that I am, it looks to me like Microsoft finally intends to terminate the option to sign drivers using the cross-certificate technique, which today is still quite useful for systems with Secure Boot turned off. But they are not doing so by closing a loophole in new kernels, which would be sensible. Instead, it looks like they are shutting down the entire "Microsoft Code Verification Root" CA, thereby making it impossible to cross-sign driver packages at all.
To me, this look like yet another example of the Redmond bubble, in which people don't have to live in the Real World. In the Real World, MANY of us are still writing drivers that have to run on Windows 7, 8, and 8.1, where attestation signing is entirely useless and cross-signing is required.
If I am reading this right, and I invite those with Microsoft contacts to correct me I'm wrong, then I can only hope that an industry outcry will once again convince them that major policy decisions cannot be made in a bubble.
