had text that was unsaved inside a Notepad for example here and I go down here and I select it and I kill it like this anything that was not saved will be lost, in addition if I had saved at least once then the file that, that data was saved in is going to be stuck in an open state. For many applications when they encounter a file that is an open state, its locked open they won't open it, they assume that somebody else has it open and they don't and the application doesn't want to risk corruption by allowing someone else to open that same file and potentially have two peoplesaving data to the same file simultaneously. So if that happens and you can't access an open file, go ahead and restart the system that'll clear the lock. Let's go ahead and start Notepad again.

Now if you need to see more details about an application that's currently running on the system on the Processes tab you can right-click the application and then come down here and hit go to Details.When you do we're taken over to the Details tab and we see the actual process that is providing this application. You can see that the Notepad.exe process is providing the Notepad application, here's its process ID number. Here's the status of the process, currently running. Here's the user that owns the process.Here's how much CPU time that process is using. Here's how much memory, and here's how much I/O the process is using and here's a description of it over here, Notepad. Now in addition to killing a process over here, on the Processes tab you could also kill the processes associated with that application over here on the Details tab. It'll basically do the same thing, select the process come down here and click End task. This time it'll warn you a little bit, it says "Hey, if you close this process uncleanly you might lose data and if it's a system process you might crash the whole system are you sure you want to do this?" and you have to decide whether it's worth it or not, sometimes it will be. If that's the case go ahead and kill the process. Let's go ahead and start Notepad again. Set Priorities 6:59-8:19 Now there's some other useful things you can do over here on the details tab. For example if I right-click on this process and go down to set priority I can actually change the priority of the processrunning on the system. Now by default it's running with a normal priority level in which case itbasically has to fight with all the other applications that are also set to normal priority for how much CPU time, how much I/O they get and so on. However if you're running a process that's kind of important that's going to require a lot of CPU attention, then you may want to change the priority level. For example, if you were editing video, or maybe you're rendering a 3D wireframe drawing or something like that, you could come in to the process and actually set its priority to above normal or even higher.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
