A Windows Script Host error on startup in Windows 11 usually appears when a script fails to run during system boot. The error message may show a missing script file or a path that Windows cannot find.
This problem is often caused by leftover startup entries, malware remnants, or corrupted registry settings. In most cases, you can fix the Windows Script Host error by removing the faulty startup script or repairing system settings. This guide explains the causes and the most effective solutions.
What Is Windows Script Host?
Windows Script Host (WSH) is a built-in Windows component that runs scripts written in languages such as VBScript and JScript. These scripts are often used to automate tasks or launch processes when Windows starts.
Some programs also create startup scripts that run automatically when you log in.
If the script file is missing or corrupted, Windows may display a Windows Script Host error during startup.
Why Does the Windows Script Host Error Appear on Startup?
The Windows Script Host error usually appears when Windows tries to run a script that no longer exists.
Common causes include:
- A program that was uninstalled incorrectly
- Malware that created a startup script
- Missing or deleted script files
- Invalid registry entries
- Broken startup items
Fixing the startup entry typically resolves the issue.
Fix Windows Script Host Error on Startup in Windows 11
Try the following solutions to remove the error.
Remove Suspicious Startup Entries
A broken startup script can trigger the error.
- Press Ctrl + Shift + Esc to open Task Manager.
- Click the Startup tab.

- Right-click them and select Disable.
Restart your computer and check if the error disappears.
Check the Startup Folder
Sometimes a script file is stored in the startup folder.
- Press Windows + R.
- Type:
shell:startup
- Press Enter.
- Look for unusual script files such as .vbs or .js.
- Delete suspicious entries.
Restart the system afterward.
Remove Broken Script Entries from Registry
If the error still appears, a registry entry may be pointing to a missing script.
- Press Windows + R.
- Type regedit and press Enter.
- Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- Look for entries referencing .vbs or .js scripts.
- Delete entries linked to missing files.
Be careful when editing the registry and only remove suspicious entries.
Run a Malware Scan
Some Windows Script Host errors are caused by leftover malware scripts.
To scan your system:
- Open Settings.
- Go to Privacy & security.
- Click Windows Security.
- Select Virus & threat protection.
- Run a Full scan.
Removing malware often resolves script-related startup errors.
Run System File Checker
Corrupted system files can also trigger Windows Script Host errors.
- Right-click the Start button.
- Select Windows Terminal (Admin).
- Type:
sfc /scannow
- Press Enter.
Windows will scan and repair damaged system files automatically.
Final Thoughts
The Windows Script Host error on startup in Windows 11 usually appears because Windows is trying to run a missing or invalid script. In most cases, removing faulty startup entries, checking the startup folder, or scanning for malware resolves the problem.
If the error continues after trying these solutions, performing a full system scan and checking registry startup entries will usually identify the cause.
