General Sentiment

Community reception has been largely positive, with users appreciating the practical improvements to File Explorer file size display and search functionality. The update addresses several long-standing reliability issues, particularly for enterprise users dealing with MDM and network storage scenarios. However, some users report the file size display feature is still rolling out gradually, and there are isolated reports of boot issues on certain hardware configurations. The 5GB download size has drawn some concern from users, though this is typical for cumulative patches. Overall sentiment reflects cautious optimism about the quality improvements without major reported regressions.
