Windows 10: Windows Script Hoist - no script engine for file extension .js

I am using Windows 10 Home on a HP i3 laptop.

Just recently I have started receiving an error pop-up which says "Windows Script Host - There is no script engine for file extension ".js"".

There doesn't seem to be a pattern to when the error appears, but it is quite frequent.
I found one Windows 10 online post which said that I needed to have java installed. I can confirm that java is fully installed.
I have found other forum posts which relate to version of Windows before Windows 10 but none of these help.

Can anyone shed any light onto what this error might be with Windows 10?.

Settings doesn't launch on windows 10 - My Fix

Hello,

Thank you for sharing the information to solve the issue regarding unable to open the Settings. This might help other Community members who are facing the same issue.

Windows Script Host (WSH) enables scripts to be run directly in Windows by double-clicking a script file or by typing the name of a script file at a command prompt. Like Microsoft Internet Explorer, WSH serves as a controller of ActiveX scripting engines.
WSH has very low memory requirements and is ideal for both interactive and non-interactive scripting needs (such as logon scripting and administrative scripting).

WSH supports scripts written in Microsoft Visual Basic Scripting Edition (VBScript) or JavaScript. When you start a script, the scripting host reads and passes the specified script file contents to the registered script engine. The scripting engine uses
file extensions (.vbs for VBScript; .js for JavaScript) to identify the script instead of using the SCRIPT tag (used in HTML). Because of this, the script writer does not have to be familiar with the exact programmatic ID (ProgID) of various script engines.
The script host itself maintains a mapping of script extensions to ProgIDs and uses the Windows association model to start the appropriate engine for a given script.

There are two versions of WSH: a Windows-based version (Wscript.exe) that provides Windows-based properties for setting script properties, and a command prompt-based version (Cscript.exe) that provides command-line switches for setting script properties.
You can run either of these versions by typing "wscript.exe" or "cscript.exe" at a command prompt.

In earlier versions of Windows, the only native scripting language supported was the MS-DOS command language. Although MS-DOS is fast and small, it has limited features compared to VBScript and JavaScript. ActiveX scripting architecture allows users to take
advantage of these powerful scripting languages, while still providing support for MS-DOS command scripts.

Hope the information provided is helpful. Feel free to write to us for any other assistance with Windows, we'll be glad to assist you.

Thank you.

 

Up on start up Windows Scrip Host error can not find script file "C\WINDOWS\run.vbs".

Hi Inderjit,

Thank you for posting the query on Microsoft Community.

It could be due to some programs running in the background.

Windows Script Host supports scripts written in VBScript or JScript. When you start a script from your desktop or from the command prompt, the script host reads and passes the specified script file contents to the registered script engine. The script engine
uses file extensions (that is, .vbs for VBScript and .js for JScript) to identify the script. As a result, you do not need to know the exact programmatic identifier (that is, the ProgID) of the script engine. The script host maintains a mapping of script extensions
to programmatic identifiers, and uses the Windows XP association model to start the appropriate engine for a given script. For more information about Windows Script Host, see

Something on your computer is trying to run a script. That is NOT a good thing unless you know exactly what it is!
