When a Windows program or your computer is not responding, freezes, or becomes unresponsive, there are several possible causes why it happened. Most of the time, it is due to the lack of system resources like memory, storage and processing capacity compared to the needed resources of the unresponsive program along with other running tasks. However, in some cases, this issue of Windows might be due to conflict between the software and hardware, software bugs or malware.
There are several measures you can do to attempt to solve the non-responsive Windows or software. The steps for troubleshooting a non-responding program are described in detail below. Nevertheless, in early versions of Windows you will be prompted by Windows to “Close the program” or “Wait for the program to response”.
Solutions to fix Windows Program or Application is Not Responding Issue
1. Use Task Manager
Press the Ctrl + Alt + Del keys on your keyboard to launch the Task Manager window as your initial attempt to fix the program’s non-responsiveness. Click on the Task Manager, then select the problematic software or task, then select End Task to end the process. Remember that all your works or inputs in the non-responsive program will not be saved once you “End Task”. If the computer doesn’t respond to Ctrl + Alt + Del, it may be deadlocked, and must be forced shutdown the computer.

2. Restart or Shutdown the computer
Restarting your computer should be the next course of action if the program still doesn’t react after being closed and reopened. Although restarting the computer could seem like a “cop-out” solution, it frequently resolves many software problems and is one of the simplest troubleshooting procedures to carry out for the majority of computer-related issues.
