WWAHost.exe (Microsoft WWA Host) is a program by Microsoft that allows some of the Windows apps to run properly. So if you came here wondering if WWAHost.exe is a virus, and you should uninstall it, then that’s not the case. It’s a helper program offered by Microsoft, located in the System32 folder and you should not be doing anything with it. The program helps some apps execute JavaScript.
What is the WWAHost.exe process?
So, it is clear that you do not need to disable it because you never know which apps might be still using it. Windows 11/10 has changed the way apps are executed and distributed, but if you still see the program, then it means some apps are dependent on it.
One thing that may happen with WWAHost.exe is that it may cause high CPU or Memory or Disk Usage. The best way to go ahead is to close the Store apps one by one and check if it drops the usage. If it does, then the app is the problem because WWAHost is only helping it to run. You can choose to reinstall or restart the Windows Store app.
If that doesn’t help, then open Task Manager using Ctrl+Shift+Esc.
- Then locate WWAHost.exe, and kill it using the right-click menu.
- Relaunch the apps, and see if the issue resolves.
Programs that keep on causing high-CPU usage are usually stuck in the loop and results in high resource usage. Hence killing the program might help.
That said, if you still suspect the program is malware, there is a way to check it. In the Task Manager, right-click on it and choose to open the file location. Now, using any antivirus program on your computer, scan the file. If the results are fine, there is nothing to be worried about.
I hope the post helped you understand how the WWAHost.exe program is used on Windows 11/10 computers and whether you should disable or delete it.
