Microsoft Lifts Upgrade Block for Windows 11 24H2: What You Need to Know
In an important development for Windows users, Microsoft has announced the removal of a long-standing upgrade block that had prevented many Windows 10 users from transitioning to Windows 11. This restriction, which persisted for over two years, primarily impacted Intel PC users due to incompatibility issues with the Intel Smart Sound Technology (SST) drivers, causing systems to encounter Blue Screen of Death (BSOD) errors.
Understanding Intel SST Technology
The Intel Smart Sound Technology (SST) serves as an integrated digital signal processor responsible for managing audio signals on various contemporary Intel devices. This functionality is crucial for enhancing sound quality and processing audio efficiently.

The Ongoing Compatibility Issues
It’s worth noting that this compatibility issue extended to the Windows 11 24H2 release as well, prompting Microsoft to impose a safeguard block on devices equipped with 11th Gen Intel Core processors. Consequently, these devices were unable to access the feature update through Windows Update.
Resolving the Compatibility Hurdle
Microsoft has provided a way for IT administrators and system admins to monitor the status of this safeguard block through the identification number 51876952. After a prolonged wait, the company has finally addressed the compatibility issues, lifting this block alongside others recently concerning specific audio and camera functionalities.
Updating Drivers: A Key Step
To overcome the Intel SST-related issues, it is essential to update the SST Audio Controller driver. Users should look for driver versions 10.29.00.5714 or later, and 10.30.00.5714 or beyond. Most devices should receive these updates through the Windows Update service. Therefore, affected users are strongly encouraged to manually check for updates to ensure they are operating with the latest drivers.
Post-Update Process
Once a compatible driver has been successfully installed, Microsoft typically indicates that the safeguard will be automatically lifted. However, please note that it may take up to 48 hours for Windows 11 24H2 to appear as available for installation. If there is no change after this period, it may suggest that a compatible driver has yet to be released for the specific hardware configuration of that device.
Seeking Support
In situations where the safeguard remains, Microsoft advises reaching out to the respective Original Equipment Manufacturer (OEM) for additional support. The company is actively collaborating with Intel and various OEMs to ensure that updated drivers are made available through Windows Update as they become ready, providing a potential alternative for affected users to resolve issues.
