Microsoft have just lifted a block preventing specific PCs from upgrading to Windows 11. In the latest bug fixes for the current Windows 11 update, Microsoft marked a severe bug preventing PCs with specific Intel 11th generation processors from successfully upgrading to Windows 11 as “resolved”. With the bug initially being discovered in 2021, Windows 11 received a fix for affected PCs within weeks of its initial discovery. Only this Friday were affected PCs finally allowed to upgrade to Windows 11 from Windows 10.

The issue was rooted in drivers for Intel Smart Sound Technology (Intel SST) on some Intel 11th gen processors. The driver, “Intel Smart Sound Technology Audio Controller”, can be accessed from Device Manager under sound, video and game controllers. The driver versions in question were & were flagged with the error.

To fix this problem, Microsoft urged Intel to release corrected versions of the drivers. Any Intel SST driver version named or as well as later versions. What’s more, Intel fixed this issue almost immediately – affected users have been directed to the Intel website to find the fixed drivers. Strangely, Microsoft decided not to have these corrected drivers automatically found and installed by Windows Update. Only this week has Microsoft removed the block preventing Windows Update from making use of the fixed driver versions. This is also likely why Microsoft updated the issue from “Mitigated” to “Resolved External” on their support website.

Once the corrected drivers are installed, either through Windows Update or manually via the Intel website, users will be able to upgrade to Windows 11 within 48 hours. If the computer can still not be upgraded to Windows 11 from Windows 10 two days after the corrected drivers are installed, Microsoft recommends contacting the device manufacturer directly for assistance.
