Welcome Pichuwong07,
Thank you for providing such a detailed description of the issue.
Since the behavior occurs in both Google Chrome and Microsoft Edge, and even when downloading an existing .URL file, it would be helpful to determine whether this is caused by the browser download process, a Windows file association change, or a security setting on the device.
Could you please confirm:
- When the file is downloaded, what is the exact file name shown in File Explorer? For example, does it appear as filename.url.download or simply filename.download?
- If you right-click the downloaded file, select “Properties”, and check “Type of file”, what does it display?
- Does the same behavior occur if you download a .URL file while signed into a different Windows user account?
In the meantime, please try these quick checks:
- Open Settings > Apps > Default apps
- Search for “.url” and verify which application is associated with the file type
- In File Explorer, enable File name extensions from the View menu so the complete file name is visible.
- Download the file again and check whether the browser is appending an additional extension rather than replacing “.url”.
If the answer is helpful, please click "Yes". If you have extra questions about this answer, please click "Comment".
