Over the last few months, Microsoft implemented a temporary block on the Windows 11 24H2 update for specific PCs. This measure was taken to prevent crashes and address compatibility issues that appeared during the rollout.
Back in November, many users reported that USB scanners and other scanning-capable devices stopped functioning after upgrading to Windows 11 24H2. To address this, Microsoft restricted the update for systems connected to these devices. Now, the block has been removed, and these PCs can proceed with the update.
The root of the issue was tied to devices using the eSCL protocol. After the update, these devices could not switch to USB mode, rendering them unrecognizable and disabling features like scanning. Affected hardware included scanners, multifunction printers, fax machines, modems, and other eSCL-compatible devices.
To mitigate the problem, Microsoft halted the update for impacted systems and warned users against installing 24H2 manually. The situation was finally resolved with the KB5048667 cumulative update, released on December 10, 2024. Microsoft stated:
“This issue was resolved by Windows updates released December 10, 2024 (KB5048667), and later. We recommend you install the latest security update for your device as it contains important improvements and issue resolutions, including this one.
The safeguard hold (ID 54762729) that was previously in place for this issue will be lifted in the coming days. Once you install the Windows update addressing this issue, it may take up to 48 hours for the Windows 11, version 24H2 update to be offered via Windows Update. Restarting your device might expedite the process.”
