The fastest native solution seems to be Win + Tab and then middle-click the Apps to close them.

The best 3rd party solution I found is 7+ Taskbar Tweaker. You can configure it to close Tasks by middle-click to the tasks entry immediately in the task bar. Unfortunately, Taskbar Tweaker seems to be tailor-fit very closely to Windows and broke with every major update (Anniversary, Creator). The maintainer each time fixed it within some weeks, but meanwhile everything defaults to the old behavior of opening new instances instead of closing old ones.

You can use the cmd but it is a little painful here's the explanation:

1 - run cmd as Administrator

2 - type the command tasklist and press Enter

3 - Now you can see all currently running programs.

4 - Now you need to use a command called TASKKILL and use the PID of every program to close.

Let's imagine if a program have PID = 21093

You'll need to use this command:

TASKKILL /PID 21093 /F

And this goes for all the PID's like this:

TASKKILL /PID 21093 1048 1592 1040 /F

PS: /F means forcibly terminate

Hi C, this is Kimberly. I'm glad to assist you today.

Unfortunately, Windows itself doesn’t have a built-in “close all without saving” command, the prompt is coming from WordPerfect, not from Windows, and it’s deliberately there to prevent data loss.

That means the only ways to bypass it are:

1. Use WordPerfect’s own settings (if available) to disable the prompt

Some older versions of WordPerfect have an option in Tools → Settings → Environment or Files to control the "Confirm save on close" behavior.

If your version has such a setting, you could temporarily turn off the confirmation prompt, close all documents, then turn it back on.

However, many versions don’t have this feature.

2. Force-quit the processes from Task Manager

If you’re absolutely sure you don’t want to save anything, you can:

Open Task Manager (Ctrl + Shift + Esc)

Go to the Details or Processes tab (depending on Windows version)

Find each wpwin*.exe or WordPerfect process (you’ll see ~25 of them)

Select them all (Ctrl-click or Shift-click), then press End Task.

This will terminate WordPerfect instantly without saving changes — no prompts will appear.

Warning: This is the software equivalent of yanking the power cord — you will lose any unsaved changes (which in your case is the goal).

3. Command-line kill (faster for many windows)

Instead of ending them one by one in Task Manager, you can run in Command Prompt or PowerShell:

Command Prompt

taskkill /IM wpwin*.exe /F

PowerShell

Stop-Process -Name "wpwin*" -Force

This closes all running instances of WordPerfect instantly.

4. Future prevention tip

If you’ll do this again, consider opening such files in read-only mode (many programs, including WordPerfect, have “File → Open → Read-Only” checkboxes) so they won’t be marked as changed, and you can close them without prompts.

Should you have more questions, please let me know.

Best regards,

Kimberly

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.

You're most welcome.
