What are virtual Bytes?
Virtual Bytes are the total amount of virtual address space that a process occupies. Similar to the working set, this set includes memory-mapped files (shared DLLs), as well as data that has already been paged out and resides on a disk somewhere.
What is virtual Bytes in Performance Monitor?
The Virtual Bytes counter indicates the current size of the virtual address space that the process is using. Some memory leaks appear in the data file as an increase in private bytes allocated. Other memory leaks show up as an increase in the virtual address space.
What is the difference between working set and private Bytes?

What is private virtual memory?
In the full-protection model, each process is given its own private virtual memory, which spans to 2 or 3.5 gigabytes (depending on the CPU). This is accomplished by using the CPU’s MMU. The memory cost per process may increase by 4 KB to 8 KB for each process’s page tables. …
