Topic: Signing of drivers, Server 2016, HLK

I welcome! A question to who has an experience of passage of tests Hardware Lab Kit and certifications of drivers under Windows Server 2016 or other Windows versions. Tell, if it is not difficult, how much it is the difficult process, what equipment is required, how many on the average on time it occupies all, etc. Also very much interests, it is how much difficult to transit certification for the file system minifilter. Read (for example, at forums OSR) what exactly for FS-minifilters it can be improbably difficult and durable procedure that there almost millions the tests, which all time are filled up and to transit certification for the given class of drivers is almost unreal. In general, are welcomed any information on a subject. Thanks!
