Answer

Hi,

Thank you for posting your query on Microsoft Community.

As per the issue description you are getting an error "Microsoft WWA Host is not responding" while testing the app which you are developing. It is crashing and giving you an the specific above mentioned error.

WWAHost.exe in Windows 8 as an executable necessary for certain Windows Apps. Windows 8 uses Javascript to execute some Metro apps, and WWAHost is the process that hosts this. Because any Metro apps are written in the same fashion as webapps, several of them need to run interchangeably within Internet Explorer.

Let’s try these methods and check if it helps.

Method 1: Run the System maintenance troubleshooter and check.

a)      Press Windows key + W and type troubleshooting.

b)      Select troubleshooting.

c)      Select view all on the top left corner.

d)      Click System maintenance follow the prompts from there.

Method 2

Try to run the app troubleshooter from the link mentioned below and if doesn't work then try other steps mentioned in the same link.

Troubleshoot problems with an app

 

Method 3

If issue persist try to check the system files are they working fine or not and to check that try to run System File Checker (SFC) tool.

SFC scan will scans all protected system files and replaces incorrect versions with correct Microsoft versions.

How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows 8.

  1. Press Windows key and X at the same time.

  2. Choose Command Prompt (Admin) from the context menu.

  3. In the command prompt, type sfc /scannow and hit Enter.

  4. Exit command prompt.
