Fix: Windows Script Host Access is Disabled on This Machine

When you start up your PC, you may be welcomed by a Windows script host access is disabled on this machine pop-up message. 

The Windows Script Host is a feature of Microsoft Windows that allows users to run scripts written in various languages. Most users may never use this feature but for those who will, this article will guide you on how to enable it.

Should I enable Windows Script Host?

Windows Script Host is a powerful scripting engine that allows you to run scripts in the background, automate tasks and add new functionality to your applications. 

Some of the tasks it can help you perform include:

• Run a program when you log on to Windows
• Report on system status at regular intervals
• Display a pop-up message when the user clicks an icon
• Executing scripts remotely on other computers 

If you’re not a developer or don’t need to use scripts, then you probably don’t need WSH. This is because malicious scripts can use to execute malicious code of their own design or even steal your passwords from your browser or email programs.

Although WSH has been around for a long time, it’s not as secure as other scripting engines, such as PowerShell. You should only use it if you are familiar with the ins and outs of the engine or need to run older scripts that rely on WSH.

The WSH is included in every version of Microsoft Windows but is disabled by default. This is because it is vulnerable to security exploits. You can enable the WSH on your system if you need to use it.

If you have enabled it but still getting the Windows script host access is disabled on this machine pop-up message, it is probably a malware or registry error. Below is how you can fix this error.
