I cannot find any documentation about this.

For good reason - this facility is deliberately undocumented by
Microsoft. :slight_smile: You need to find some other way of doing what you want to
do (if you tell us what we can help you).

This is not documented. And for what purpose do you need this?

I wanted to use it in order to create new thread in user ring3 process.
Standard solution (CreateRemoteThread()) does not fork on XP 2003 servers if
target process has other user credentials or belongs to other desktop than
calling one.

This is the case even if you have PROCESS_ALL_ACCESS to the process
handle you’re passing to CreateRemoteThread? That sounds like a bug in
2k3 Server if true. Perhaps there is an additional privilege you need to
enable.

If you really need to send a kernel APC, see this article:
