Microsoft has partially addressed known issues impacting Windows 10 devices with certain Conexant or Synaptics audio devices after investigating ongoing errors since May 2020.

Microsoft has also removed some of the safeguard holds blocking the affected systems from upgrading to the latest Windows 10 version.

Issue resolved for two out of four safeguard holds

The known issue impacting computers with Conexant audio drivers has been under investigation since May 2020 when Microsoft released Windows 10, version 2004.

Redmond has resolved the issue for safeguard IDs 25702662 and 25702673 as of December 11, 2020.

'Please note, if there are no other safeguards that affect your device, it can take up to 48 hours before the update to Windows 10, version 2004 or Windows 10, version 20H2 is offered,' Microsoft says on the issue's Windows Health Dashboard entry.

'We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.'

While Microsoft does not recommend circumventing safeguard holds, you can still do that using the Media Creation Tool or a newly included Windows 10 group policy specifically designed to enable users to bypass update blocks.

To work around Windows 10 update installation issues, users are advised to use this update problem troubleshooter or this guided walk-through.

Problems and errors impacting Windows 10 devices under safeguard IDs 25702617 and 25702660 are still under investigation.
