Just maybe you can take some of that money and hire proper QA testers instead of relying on all your customers.
Glad going well for Mark Russinovich though. I like him and his Sysinternal tools. I know others have worked on them but if it wasn't for him and Bryan they may never have existed. Enjoy his fiction books as well.
Although he did slightly annoy me a few years but in an interview about Azure and the Cloud where he said some engineers don't like the Cloud as they know it will put them out of work. Well yes and no stopped watching after that comment, as came across a bit smug.
Other than that he seems like a nice and honest guy. Pointed out to MS how UAC was flawed (although still exists) his presentations of Case of the Unexplained have always been good (I think he might of now given them up :( he's not done one this year and said he's so busy with Azure now he's hired someone to take on the Sysinternals development). He's helped a few times when I've emailed him and was kind enough, him a David Solomon, to allow me to upload the old Sysinternals training video library from back in 2006 to YouTube so they'll always be preserved.
