What Is Wwahost.exe?

It is a helper program offered by Microsoft, located in the System32 folder, and you should not be doing anything with it. Some Metro apps on Windows 10 run in JavaScript, and WWAHost is the process that hosts this.

Any Metro program can run alternately on Internet Explorer because they are all created similarly to web apps. Microsoft describes WWAHost as “an Internet Explorer-based rendering platform.”

In Windows 10, WWAHost.exe is a secure and crucial process. Like svchost.exe hosts.dll files, it serves as a host for Metro app processes. To ensure that Windows 10 systems continue to operate normally, it is advisable to leave this operation unattended.

Can It Be Disabled?

So it is evident that you do not need to disable it because you never know which programs may still be using it. Although Windows 10 has altered how apps are downloaded and operated, if you can still see the program, it suggests some apps still rely on it.

One potential issue with WWAHost.exe is that it could result in high CPU, memory, or disc usage. The best action is to close each Store app individually and see if the user decreases. If it does, the app is the issue as WWAHost is merely assisting in its operation. You can either restart or reinstall the Windows Store app.

Programs that repeatedly use many CPU resources are typically in a loop and consume many resources. So, terminating the software might be helpful.

However, there is a technique to examine the program if you are still concerned that it might be malware. Right-click on it and select to open the file location in Task Manager. Now scan the file on your PC using any antivirus software. If the results are satisfactory, there is no need to be concerned.
