All answers I could quickly find on this topic involve either the tip Molly gave or using an application (or coding it yourself). For example (I haven't tried this), Close All Windows.

Also, by pressing Ctrl + Shift + Esc you get the Windows Task Manager, where you can see all running applications at once (among other things), select them, and End Task them.

September 24, 2019 -

I selected 100 over videos and pressed enter. I thought it would start from beginning and play it from start to end. Similar to what i would do if i opened multiple images.

Well i selected 100 over videos and pressed enter. Now my computer is stuck because there are too many videos opening at once and its too slow. Even pressing control alt del is really slow. I want to kill all processes and kill anything else that is coming up as well. I closed all windows using task bar but it only killed the ones open and not the ones that were opening.

Now my computer is slowly filling up with the prompt "The application is not responding. This program may respond again if you wait. Do you want to end this process?" This is just one of the prompts for my 100 over prompts which will come later.

If this happens again, is there a command i can press on my computer to cancel everything and freeze all processes from continuing without shutting down my computer? Thanks

r/techsupport on Reddit: How can I gracefully close all open apps except Explorer with one click or keystroke?
June 20, 2024 -

I'm doing some testing and frequently need to gracefully close all open apps either before running a program or rebooting. The batch file and PowerShell methods I've tried shut down chrome improperly, so I need to restore all open tabs. I want to simulate closing the app manually.

The main apps I typically have open are Chrome, Word, Titan Mail, Thunderbird, an image management program, Photoshop, possibly other Office or Adobe programs, and Notepad.

How "gracefully" are you talking? There are multiple ways to close a program. The batch file/PowerShell method might be graceful or not, depending on exactly which commands you used. One option is to forcefully terminate each process/process group before shut down. There are also commands to gracefully ask a program to terminate. Generally it's the same command (taskkill/Stop-Process), without the /f/-force parameter. You can also interact with the program's GUI to close it, eg. using Alt+F4 keyboard shortcut,or clicking the X button in the top right (if there is one), or using File->Close in the menu bar (if it has one), or right-clicking the program icon in the taskbar and selecting Close Window. Applications may respond differently between graceful requests to terminate from the OS, and the GUI options to close. For example you mentioned Chrome, where the behaviour to automatically reopen tabs only occurs if the GUI is used to close the browser (and the option to automatically restore tabs is set), but not if you forcefully close it via command line (taskkill /f /IM chrome.exe). However it will restore tabs if you do it gracefully (taskkill /IM chrome.exe). Not all programs will necessarily behave the same way, however both Chrome and Word do.If you want to ensure you get the desired behaviour, the only reliable way to reproduce a GUI close is to use automation tools to simulate the same GUI interaction. You mentioned AutoHotKey in another comment, and yes that's one solution to achieve this. The problem is, if you want to automate this GUI interaction you also need to handle scenarios where the program refuses to close. Like in Word or Notepad, if you have an unsaved document, the GUI methods will prompt the user to save changes first. Each program will behave differently, so you'll need to account for every app you might possibly have open, and the different behaviours it might have to different states. At that point you either have an overly complicated automation, or you only have partial automation with user intervention required to handle any exceptions. Or you just accept the fact that terminating gracefully via command line is the easiest solution, even if some applications might not handle it the way you want. If you're willing to dig deeper, you might be interested in ARSO. But it'll only work with applications that explicitly support it, and I don't know of any way to trigger it manually.
