Synapse for Windows - V4.0.86.2610200951 / Chroma for Windows - V4.0.63.2610020954
NOTICE: END OF WINDOWS 10 SUPPORT FOR RAZER SYNAPSE 4
Following Microsoft's end of standard support for Windows 10 back on October 14, 2025, full support for Razer Synapse 4 on Windows 10 ends on October 14, 2026. As with Microsoft, this is a firm change: bug fixes and technical support for Synapse 4 on Windows 10 will not continue beyond this date.
From October 14, 2026 until October 12, 2027, any bug fixes released for Synapse 4 on Windows 10 will be limited to security updates only, mirroring Microsoft's own extended security updates for the platform. After October 12, 2027, Windows 10 support and compatibility will no longer be maintained for Synapse 4. Synapse 4 can still be used on Windows 10 and will still receive feature updates, but we cannot guarantee full functionality as we will no longer fix or address any bugs seen exclusively on Windows 10.
Moving forward, we recommend upgrading to Windows 11 to ensure the best possible experience. For more information on Microsoft's Windows 10 end of support and extended security updates, please visit Microsoft's official support page.
