Microsoft: October updates break USB input in Windows Recovery

Microsoft has confirmed that this month’s security updates disableUSB mice and keyboards in the Windows Recovery Environment (WinRE), making it unusable.

WinRE is a minimal Windows-based environment that operates independently of the main operating system, allowingusers to repair, restore, or troubleshoot the operating system even when Windows fails to start.

However, as Microsoft revealed in a Windows release health dashboard update on Friday, after installing the KB5066835 October 2025 security updates, users will no longer be able to use their USB-wired mouse and keyboard while in recovery mode.

The company added that the input devices will still work while using the Windows operating systems, although if the users need to use WinRE they might already experience issues which require troubleshooting or repairing the OS.

“After installing the Windows security update released on October 14, 2025 (KB5066835), USB devices, such as keyboards and mice, do not function in the Windows Recovery Environment (WinRE),” Microsoft said.

“This issue prevents navigation of any of the recovery options within WinRE. Note that the USB keyboard and mouse continue to work normally within the Windows operating system.”

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
