Hi Pasquale,
Thank you for posting question on Microsoft Windows forum!
Based on your query of removing the security warning when opening a file with VLC. Actually, it generally a Windows security feature, not specifically a VLC setting. Windows displays this warning for files that originate from the internet or other "untrusted" locations, as a way to protect you from potentially malicious software.
You can try the following steps to address that.
1."Always ask before opening this file" checkbox (for individual files):
- The simplest way to stop the warning for a specific file is to:
- When the "Open File - Security Warning" dialog appears, uncheck the box that says "Always ask before opening this file" at the bottom of the window.
- Click "Open" or "Run."
- This will prevent the warning from appearing for that specific file in the future. However, if you download many files, this can become tedious.
2.Unblock the file (for individual files):
- Windows adds a "Zone.Identifier" alternate data stream to files downloaded from the internet, which triggers the security warning. You can manually unblock a file:
- Right-click on the file you want to open.
- Select "Properties."
- In the "General" tab, look for a "Security" section at the bottom.
- If present, click the "Unblock" checkbox.
- Click "Apply" and then "OK."
3.Adjusting Internet Options (affects all files from the Internet Zone):
- This is a more general solution that can prevent the warning for all files originating from the "Internet Zone."
- Open the Run dialog box by pressing Windows key + R.
- Type inetcpl.cpl and press Enter. This will open "Internet Options."
- Go to the Security tab.
- Select "Internet" (usually the globe icon).
- Click the "Custom level..." button.
- Scroll down to the "Launching applications and unsafe files" option.
- Change the setting from "Prompt" to "Enable (not secure)".
- Click "OK," then "Yes" to confirm, and then "Apply" and "OK" in the Internet Options window.
- You may need to restart your computer for the changes to take effect.
- Important Note: Enabling "Launching applications and unsafe files" to "Enable" means that Windows will no longer warn you before opening potentially unsafe files from the internet. This significantly reduces your protection against malware and should only be done if you are absolutely sure of the safety of the files you open.
Hope the above information is helpful!
