Previously, I would look in Task Manager for a *32 next to the process name in Task Manager to tell what platform the process is running on:
However, in Windows 8 and 10 (on the details tab) this is not present:
How can I see, in Task Manager, if my processes are running as 32-bit or 64-bit?
You'll find that 64bit windows keeps two copies of system executables. There's c:\windows\system32 for 64bit apps, and "c:\windows\syswow64" for the 32bit versions.
Navigate to the syswow64 folder and look for taskmgr.exe, double click it to run the 32bit version, after task manager opens you will notice "taskmgr.exe*32" in the list, any process in the list with *32 means it is a 32bit version running.
This is a special tool to deal with hung and frozen programs. It helps you identify the actual process that caused the freeze:
The analyze wait chain tree shows which processes (root nodes in the tree) are using, or waiting to use, a resource that is being used by another process (child nodes in the tree) and is required for the selected process to continue).
So if you have an unresponsive process, this tool will show you a resource dependency tree and it will highlight the frozen child processes (if any) with red color. By ending the correct ones you might still save your data in the parent process.
See this or this blog posts for a detailed description.
As to the wait chain, see the official API documentation:
A wait chain is an alternating sequence of threads and synchronization objects; each thread waits for the object that follows it, which is owned by the subsequent thread in the chain.
In fact, the Wait Chain Traversal API has been around since Windows Vista. For example, Windows 7's Resource Monitor has already had the same context menu item:
So in Windows 8 it was merely moved to a more convenient location in the Task Manager (copied, to be exact, as Resource Monitor still has it too).
