I do not wish to view the leaked copies of Windows source code, unfortunately. It does have potential legal ramifications, in the United States. If someone who doesn't care can attempt to audit it, that would be absolutely great. That said, KiInitializeContextThread isn't 'secret' enough to not appear, it is a well-known bit of internals. Here you can find some docs about it on Microsoft's own website, albeit I have…
If Microsoft cared, they wouldn’t be hosting that on their very own servers. GitHub belongs to Microsoft. They could pull that down at any time just because they feel like it. But they haven’t. That’s a pretty solid sign that there’s not any legal consequence to viewing it.
(You're also not allowed to contribute to the Wine CRT if you've ever seen the CRT source that's legally distributed with the Windows SDK.)
