Can't upload snapshot 

A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. 

Processes that use tool help functions access these lists from snapshots instead of directly from the operating system. The lists in system memory change when processes are started and ended, threads are created and destroyed, executable modules are loaded and unloaded from system memory, and heaps are created and destroyed.

Snapshot

An application consists of one or more processes. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread
