How to Install the Windows 11 Recovery Mode Emergency Patch

If you count on Windows 11’s native recovery tools, you need one important update before disaster strikes. Microsoft has shipped an out-of-band fix, KB5070773, to correct a bug that left USB mouse and keyboard input broken in the Windows Recovery Environment (WinRE). Without this patch, the vast majority of PCs are simply unreachable in recovery mode — i.e., when you need control the most.

What the patch fixes in Windows 11 Recovery Environment

Based on information included with the latest updates released by Microsoft and the developer’s own Windows Release Health dashboard, a recent Windows update caused a USB Human Interface Device issue in WinRE. The problem affected Windows 11 24H2 and 25H2, as well as Windows Server 2025. What this meant in practical terms is that users booting into recovery mode discovered that they were unable to move a cursor, press Enter, or select repair options.

PS/2 peripherals were still supported, but these days few motherboards ship with PS/2 ports. As a result, many users had no way to access Safe Mode, Startup Repair, System Restore, or Reset this PC in the event that Windows was unable to boot. KB5070773 fixes the USB input issue in WinRE, restoring the ability to use your keyboard and mouse when running recovery tools.

Who is affected, and why it matters for recovery mode

WinRE is a stopgap when Windows is not bootable. Among other uses, it can restore boot records, roll back problematic driver updates, and recover from failed updates by starting the system in a minimal device state — Safe Mode. It also offers guidance for BitLocker recovery keys. If your keyboard and mouse don’t function there, even something as simple as a quick fix can turn into an all-out outage.

This isn’t a niche scenario. According to industry trackers like StatCounter, about one-third of Windows desktops are now running Windows 11. At that scale, a recovery-mode input failure can lead to some very unpleasant disruptions for both homes and enterprises, not the least of which are going to be laptops that rely entirely on USB for external input.

How to download and install the Windows 11 WinRE update

On a Windows 11 computer, click Settings, then select Windows Update, and then Check for updates. Find and install the cumulative update KB5070773. Restart when prompted. WinRE should detect USB keyboards and mice as normal after the reboot.

IT administrators can push the fix to users’ machines using Windows Server Update Services or through endpoint management tools like Microsoft Intune. If you keep golden images or custom recovery partitions/images, make sure that the WinRE image is updated after deployment so new devices get the fix.

Quick way to test the fix in Windows Recovery Environment

To be sure everything is working correctly in advance of an emergency, it’s a good idea in the Start menu to hold down the Shift key while clicking Restart on the Power icon, and your PC will boot into WinRE. Browse to the Rescue Menu using your keyboard’s arrow keys and press Enter, then back out without applying any changes. You’re in the clear so long as your input responds normally when you are asked a question.

If you’re stuck before the update, try these options

If you are already at a stage where WinRE is not responding to input, the options are few but not zero. If you have a legacy PS/2 keyboard it might still work on desktops with the appropriate port. Enterprise systems may have the option to take advantage of out-of-band management or a remote KVM from the system’s firmware. You can also boot from alternative Windows installation media and employ its recovery tools, after which you should install KB5070773 once the system boots normally.

Why this matters: maintaining stability in Windows WinRE

Reliability in recovery mode isn’t just a matter of convenience — it’s part of your resilience plan. WinRE today is core for Windows recovery scenarios, especially on Secure Boot and BitLocker-capable devices. A busted recovery environment can easily transform a 10-minute rollback into hours of data-loss exposure, user downtime, and help desk rampage.

Microsoft’s decision to ship an out-of-band update highlights the seriousness. This is an out-of-band release, meaning admins should install it as soon as possible instead of waiting two weeks for the next Patch Tuesday release. The company’s KB5070773 documentation spells out the objective: wrest control back from the one place you can least afford to lose it.

What the IT team can do now to safeguard recovery tools

Focus on deploying to the Windows 11 (24H2) release and newer versions, as well as to Windows Server 2025 hosts. Test it on a pilot group while you boot WinRE and make sure that USB input works at the different menu points. Be especially wary of systems where you might need to recover with BitLocker (remote workers’ laptops, kiosks that use USB-only peripherals).

Record the steps to verify for your service desk, and plan to review the way you image so that your new device rollouts include patched WinRE. Making recovery reliable is basic security hygiene — and the difference between a quick fix and an outage.

Bottom line: Get KB5070773 installed now, so that your recovery tools are there waiting for you when or if you need them, not after.
