How to close all QuickBooks processes at once:
You can close them all at once. For example, QuickBooks might have a different name in different windows systems. Closing QuickBooks processes all at once is a bit easy. The steps to be followed here are:

• At first, press Ctrl + Shift + Esc keys to open the task manager.
• Hit a click on the processes tab.
• Click on QuickBooks and opt for the end task option.

If that does not work, you can

Tip: If you don’t want to restart your computer, you can end the appropriate process in Windows Task Manager.

• For this, open the computer’s task manager by right-clicking the taskbar at the bottom of the system.
• You can open the task manager by pressing Ctrl + Shift + Esc keys.
• Now, move to the processes or details tab and look for multiple instances of QuickBooks processes running.
• The QBDBMgrN.exe is the culprit in the details tab.
• And then hit a right click to close down the processes while leaving one open.
• Lastly, carry out the steps you performed in the commerce sync connection.
