How can I determine what programs/processes are slowing down my PC?

You can use the Windows Task Manager to view and manage all running processes. The Task Manager Windows displays a list of applications and processes currently running on your system and helps you determine which applications or processes are slowing down your PC. You can also use third-party tools such as Process Explorer, Resource Monitor, and System Explorer to monitor processes on your PC and figure out which ones are causing your computer to slow down.
