I have multiple instances of the same program running. Say I notice in the process tab that one of the instances is using 22GB of RAM. How can identify which of the instances this is, i.e. switch to the associated window? All I see is the option to kill the process, but I'd rather investigate the massive RAM use in a "non-destructive" way.

Use Process Explorer, it allows you to identify the window and then you can check the properties of the process to figure out the command line used. This command line will help you determine what exactly has been launched, this helps to figure out where Java applications and scripts are located...
Just drag the icon over the window.
For a complete list of start-up applications, services and drivers; check Autoruns.
This should get you some of the way there.
For detecting if Task Manager is open - use something like this:
tasklist /fi "WINDOWTITLE eq Task Manager - Google Chrome" /v | find "chrome.exe"
In a batch file you will probably need to escape the pipe character:
tasklist /fi "WINDOWTITLE eq Task Manager - Google Chrome" /v ^| find "chrome.exe"
Then use an %ERRORLEVEL% check to see if you it found it and kill them all:
if "%ERRORLEVEL%" == "1" TASKKILL /IM chrome.exe /F
I'll leave you to loop in batch (consider adding a sleep too).

Download something far more powerful called Process Explorer from SysInternals/Microsoft, right-click the instance, open the Window sub-menu and click on Bring to Front.
