How to fix winsqlite3.dll update in windows server

Hello,

This DLL is part of the Windows system libraries and is updated through cumulative Windows Updates rather than as a standalone package.

To address this issue, we recommend the following steps:

1. Ensure your server is fully updated by running Settings > Windows Update or using sconfig on Server Core.
2. If the issue persists, run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to repair any corrupted system files.
3. If the DLL is flagged by security tools (e.g., due to CVE-2025-6965), Microsoft has acknowledged this and will include fixes in future cumulative updates.
4. Avoid manually replacing the DLL, as it may cause system instability or fail signature checks.

If this guidance helps resolve your issue, feel free to mark this answer as accepted so others can benefit too. I am here if you need further assistance.

Best regards,

Domic Vo.
