I mean... some process like svchost.exe, i can't inject in them using C#, but... C++ does it without problems.

Why?... i need AdjustTokenPrivileges for that? or... Ring0 privileges?

If svchost.exe is owned by you, you should be able to access it no matter what. If it's owned by another user or System and you are calling C# app as your user you won't have access to it. Welcome to The Wonderful World of messed up file perms.

From MSDN on AdjustTokenPrivileges http://msdn.microsoft.com/en-us/library/aa375202%28v=vs.85%29.aspx
Quote:

Remarks

The AdjustTokenPrivileges function cannot add new privileges to the access token. It can only enable or disable the token's existing privileges. To determine the token's privileges, call the GetTokenInformation function.


Further explanation of service token privileges.
