This issue has been brought up a few times, and the answer unfortunately seems to be no. If you know your way around source code, the Chromium project may be of interest. You can hack away at the code and remove the warning.

What are the best performance chrome://flags that should be enabled by Chromebook users?
I recommend that you leave the flags alone. Flags are designed for use by the developers while they are testing and finalizing new features. They are not intended for routine use by consumers. They will disappear without notice. They can cause instability, crashes, and even boot problems that require a full Recovery. Of course, you won't believe me, so be prepared to lose ALL local data (ChromeOS and Linux) without warning, at any time. Store important files in Drive and make backups. You have been warned.

Dear Pooja Bhagchandani,

Thank you for reaching out to the Microsoft Community.

While I understand your interest in enabling the Parallel Download feature in Google Chrome to improve your downloading experience, it’s important to note that Google Chrome is a third-party application. As such, Microsoft does not directly manage or provide fixes for Chrome-specific features.

That said, I can guide you on how to enable the Parallel Download feature in Chrome and direct you to the appropriate resources for additional support.

How to Enable Parallel Downloading in Chrome

Parallel Downloading is an experimental feature in Chrome that can speed up downloads by creating multiple connections to download files simultaneously. To enable it:

  • Open Google Chrome.
  • Type chrome://flags in the address bar and press Enter.
  • In the search bar at the top, type Parallel Downloading.
  • When the Parallel Downloading option appears, click the dropdown menu next to it and select Enabled.
  • Click Relaunch to restart Chrome and apply the changes.

Based on my testing on Chrome V131.0.6778.205, this feature is enabled properly in the labs.

For detailed support and to address specific issues, I recommend visiting the Google Chrome Help Community or reaching out to Chrome's support team:

Google Chrome Help Community: Ask a Question - Google Chrome Community

Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites, or any support related to technology.

The dedicated team and community members there will be better equipped to help you troubleshoot and provide specific advice regarding Chrome features.

If you have any other questions or concerns, feel free to reach out.

Best Regards,

Martin | Microsoft Community Support Specialist
