Several users reported that they were seeing a BSOD or blue screen of death error after they installed the new Windows 11 21H2 feature update on their systems.
Following the reports, Microsoft confirmed the compatibility issues with some versions of the Intel Audio drivers and the Windows 11 Operating System.
Soon, Microsoft posted a doc where the company explained
“Intel and Microsoft have found incompatibility issues with certain versions of drivers for Intel Smart Sound Technology (Intel SST) and Windows 11. Windows 11 devices with the affected Intel SST driver might receive an error with a blue screen.”
Microsoft on its Windows Health dashboard explained that the issue is caused by the Intel SST driver version 10.29.0.5152 and earlier or 10.30.0.5152 and earlier.
Additionally, Microsoft has put compatibility lock to secure the upgrade experience for the system impacted by the recent Intel SST drivers issue.
Meanwhile, Microsoft details a workaround for the issue where the users need to check for any driver update from Intel and install the update as soon as possible.
The issue can be fixed after the user updates their Intel SST drivers to either 10.30.00.5714 and later version or 10.29.00.5714 and later version.
On installing the Intel SST driver update, the compatibility lock should be lifted and there shouldn’t be any problem upgrading to Windows 11.
Besides this, Microsoft says that it may take up to 48 hours before Windows 11 upgrade is offered to the users who have updated their Intel SST audio drivers.
As of now, users can’t upgrade to Windows 11 on virtual machines created with Oracle Virtualbox.
