Topic: Access Denied by operation with another's process from under an exclusive account

Kind time of days! There is a process launched from under the local manager. Attempt to remove from it  or to open with a totality of the rights, to receive a token, is completed with Access Denied. Setting does not help with client process SeDebugPrivilege. Start of client process from under System does not help. Ideas?

It is possible to try to reach through Process Hacker, he is able to bypass the majority of basic protection (using the driver). But, as already wrote, access even for managers and system  can be closed the built in means, it ObRegisterCallbacks and protected processes on Vista and above, and still Protected Processes Light (Win8.1 +) and Trustlets (Win10). Google - "The Evolution of Protected Processes" and "Battle of SKM and IUM" (A. Ionescu).

Attempt to remove  through Process Hacker ended as:--------------------------- Process Hacker--------------------------- Unable to create the minidump: It is refused access. That is now it is necessary  all calls through  the driver? We can kill the rights to process that it could not use similar protection?

Installed  it is possible to remove (at own risk) any antirootkit-utility. For example, GMER.
