Microsoft has finally lifted a compatibility hold blocking Windows 11 upgrades on systems with Intel 11th Gen Core processors and Intel Smart Sound Technology (SST) audio drivers.

Microsoft is blocking Windows 24H2 upgrades on systems with incompatible Intel Smart Sound Technology (SST) audio drivers due to blue screen of death (BSOD) issues.

Certain Windows 10 PCs have been unable to upgrade to Windows 11 since late 2021, when Microsoft identified problems with drivers for Intel's Smart Sound Technology.
