Microsoft has just confirmed an emergency update for Windows 10, after an increasing number of users reported May’s mandatory security update breaking Windows. Affected users have been hit with BitLocker Recovery screens and even dreaded Blue Screens of Death after downloading and trying to install the latest critical update.

“Windows 10 might repeatedly display the BitLocker recovery screen at startup,” the company warned, confirming an out of bounds update via Microsoft’s Update Catalog.

The issue affects users “on devices with Intel Trusted Execution Technology (TXT) enabled on 10th generation or later Intel vPro processors.” Those who have not yet deployed May’s update should install the out of bounds update instead.

For those who have tried to install the update and are now stuck, Microsoft says:

Windows Latest was first to flag the issue, reporting that “the KB5058379 install starts, but ends up at ‘Enter the recovery key to get going again (Keyboard layout: US)’ screen, and there’s a text field to add the recovery key. In some cases, there’s a BSOD as well.”

Microsoft has again warned Windows users that its support team “doesn’t have the ability to retrieve, provide, or recreate a lost BitLocker recovery key,” but can use this link to find your BitLocker recovery key.” This issue and fix primarily applies to enterprise users, as “consumer devices typically do not use Intel vPro processors and are less likely to be impacted by this issue.”

May is proving an interesting month for the Windows-maker, with the wider release of its controversial Recall photographic memory for Copilot+ owners and the continuing drive to push 700 million Windows 10 users to upgrade ahead of October’s deadline.
