A new bug is affecting some Windows 11 and Windows 10 users, and it's been caused by Microsoft's July cumulative update.
It's also a bit odd that the BitLocker recovery screen is presented to some users after they boot their devices, which must be an unpleasant surprise for those affected.
According Windows CentralSeveral versions of Windows 11 are affected by the issue, including Windows 11 versions 23H2, 22H2, and 21H2, as well as Windows 10 versions 22H2 and 21H2, among others.
Microsoft's monthly cumulative updates (known as “Patch Tuesday” updates, since they arrive on the second Tuesday of every month) bring quality-of-life improvements and security fixes to Windows 10 and Windows 11. And, of course, bugs sometimes, like this July offering.
BitLocker is a tool that offers drive encryption to keep your data safe. It can be set up on Windows 11 Pro (or the business and education versions of the operating system), but Windows 11 Home does not support BitLocker; however, it does offer a device encryption option (basically, a lightweight alternative).
As a result, we obviously don't expect Windows 11 Home users to be affected by this bug, but those using Windows 11 Pro may need to be vigilant when applying the July Update.
Microsoft is investigating the bug, but what can you do in the meantime?
Microsoft is aware of this issue and has been updated The Windows 11 version status dashboard with details about the bug. The software giant warns that the bug is more likely to occur if you have device encryption enabled and BitLocker turned on. You can find this option in the Settings application, going to the Privacy & Security section and clicking on Device encryptionIf you don't see Device Encryption, it may not be available on your device.
In any case, after applying the July update, if you encounter the failed BitLocker recovery screen (when you weren't expecting to see it), there is currently a workaround available: entering a BitLocker recovery key. This key is available through your Microsoft account and can be recovered by signing in to Microsoft Recovery Screen PortalAfter entering the recovery key, your PC should continue to boot normally.
Unfortunately, this is currently the only known fix for the issue, but Microsoft is working on the case and says it is investigating the bug, so we hope to find a fix soon. If Microsoft can find the time while still helping to shut down the massive CrowdStrike outage, that is.
