Some users in the Windows 11 testing program have experienced significant issues with the Recall feature, which is intended to enhance user experience through AI-driven search capabilities. Microsoft has identified a bug related to the optional update KB5046740, which interferes with Recall's functionality when installed before Dev build 26120.2415. This bug prevents Recall from saving snapshots necessary for its advanced search features. Microsoft has advised against installing the preview update before joining the Dev channel and has not provided a clear resolution for those affected, leaving them with limited options, such as reinstalling Windows 11. Recall is currently designed for Copilot+ PCs powered by Arm-based Snapdragon processors, narrowing the number of potential testers.
