What Causes a Windows Script Host Error

Windows Script Host (WSH) is a built-in automation tool in Windows that allows administrators to execute various scripts like VBScript and JScript. While WSH tasks are fairly common and run in the background, you might sometimes encounter errors like “Windows Script Host access is disabled on this machine.”

Errors like these can usually be traced back to registry errors, malware infection, VBS script file issues, or other corrupted files. To fix a Windows Script Host error you’ve encountered, you can try the below fixes in sequence.

1. Check Windows Script Host in Registry

Due to a number of reasons, Windows Script Host might simply be disabled on your system. A program you installed or some system settings you don’t remember changing could be the reason behind this. To check if this is indeed the case, you can use the Registry Editor as follows:

1. Press Win + R to open the “Run” dialog box.
2. Type regedit and press Enter to open the Registry Editor.
3. Open “HKEY_CURRENT_USER -> Software -> Microsoft -> Windows Script Host -> Settings.”

4. On the right-hand side pane, double-click the “Enabled” value and check the “Value data” field. Make sure it’s set to “1” and click “OK.”

5. If there is no “Enabled” value, you can create it. Right-click in the empty space on the right-hand side pane and select “New -> DWORD (32-bit) Value.” Set the name of this newly-created value to “Enabled.” Click “OK” and set its “Value data” to “1” to complete the process.

6. Restart your computer for the changes to take effect.

2. Use Microsoft Safety Scanner

Windows Script Host errors are often caused due to malware infection. You can use a free tool called Microsoft Safety Scanner to scan your system for malware and remove them to fix your WSH error. You can also employ the help of a third-party antivirus program to run a system scan. Here’s how to use Microsoft Safety Scanner.

1. Download Microsoft Safety Scanner from Microsoft’s website.
2. Launch the downloaded executable, and select “Full scan” for a comprehensive malware check of your system.

3. Click “Next” to initiate the scan and follow the on-screen instructions to complete the process.

Good to know: Windows Defender is enough for all the antivirus protection you need on your system.

3. Check VBS File Value in Registry

The Virtual Basic Script (VBS) is a Windows file containing information required by the Windows Script Host tool to run several scripts. It can sometimes be configured incorrectly, causing one or more WSH errors. You can check the VBS file using the Registry Editor to try to fix the errors.

1. Open Registry Editor from the “Run” dialog box.
2. Open “HKEY_CLASSES_ROOT -> .vbs” and double-click the “(Default)” value on the right-hand side pane.

3. Ensure that the “Value data” is set to “VBSFile” and click “OK.”

4. Don’t forget to restart your computer for the changes to take into effect.

4. Delete Entries After Userinit in Registry

Users can also encounter Windows Script Host errors during system startup. To fix these kinds of issues, you can delete a few registry entries in the Registry Editor and see if it helps. Follow the steps below to do so:

1. Open Registry Editorfrom the “Run” dialog box.
2. Open “HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows NT -> CurrentVersion -> Winlogon.”

3. Delete all the entries following “Userinit.” In this example, these are “VMApplet” and “WinStationsDisabled.”

4. Double-click “Userinit” and ensure the “Value data” is set to “C:\Windows\system32\userinit.exe.”

5. Click “OK” and restart your computer.
