This function is used to generate GUIDs at kernel mode. According to documentation: "ExUuidCreate returns STATUS_SUCCESS if successful; otherwise, if the system is not ready to generate a new UUID, it returns STATUS_RETRY."

Moving to www.shcherbyna.com

I always wanted to have an own domain, hosting mail, blog and probably some important files for me. However, I always felt the leak in time, and this direction was non primary for me. Until today.

As you probably have mentioned, the server msmvps.com (which is hosting http://msmvps.com/blogs/v_scherbina/) was dead for approximately one week. During these 7 days my brain reorganized some tasks, and I decided to make independent blog which (theoretically) will be constantly up : ).

So let’s welcome www.shcherbyna.com web site. I am going to move completely on this blog, but for some period of time I will be duplicating posts to “Ab origine” as well.
