What is the Process Explorer and what is it used for?
The Process Explorer can show specific values concerning memory usage of a process. Relevant values are Virtual Size, Working Set and Private Bytes.
These values can be seen either in the properties window of a process (double-click in the list or Properties in the context menu) or in the process list - to do this, select the corresponding columns under View > Select Columns under Process Memory.
The Windows Task Manager uses different labels, which is a little bit confusing. The Virtual Memory Size doesn’t mean the Virtual Size, but the Private Bytes.
