Can we assume this is a Windows question? XP x64, Vista, 7?

In Windows 7 I believe a 32-bit application running in a 64-bit OS has a *32 after its name in the Task Manager...

Just to add to this old answer, yes use Process Explorer. You can right click on the columns and select Image Type to show which processes are 32 bit and which are 64 bit. Run Process as Administrator to see some services.

Unlike in Windows 7 task manager where 32-bit processes are shown with *32, in Windows 8 and 10 they'll be shown with (32 bit) at the end. No need to go to the Details tab and add another column!

In compact mode they're shown in the same way, but in less detail compared to the Processes tab and Details tab
