Microsoft warns users of emergency update affecting all Windows users
Microsoft has just released a new emergency update after users reported significant errors with the last version, as it ended up causing PC crashes and the dreaded 'blue screen of death'.
Windows updates are something many people put off for as long as possible, but they remain an essential part of keeping your PC up to date and protected from any security flaws that might emerge.
Sometimes Microsoft will release mandatory versions that force you into the new version any time you turn off or restart your PC, but a major blunder has caused some users to enter a crash loop of sorts after installing the critical update.
What issues does the new Windows update cause?
As reported by Forbes, some users are reporting error messages to do with BitLocker Recovery, alongside the horrors of the blue screen of death that any veteran Windows users won't ever want to see.

Essentially, it means that you can't access your PC in any form whatsoever, and it can even make downloading emergency updates designed to fix this exact issue quite challenging if you don't know what you're doing.
Explaining the issue, Microsoft has detailed: "We are aware of a known issue on devices with Intel Trusted Execution Technology (TXT) enabled on 10th generation or later Intel vPro processors.
"On these systems, installing the May 13, 2025, Windows security update (KB5058379) might cause Isass.exe to terminate unexpectedly, triggering an Automatic Repair. On devices with BitLocker enabled, BitLocker requires the input of your BitLocker recovery key to initiate the Automatic Repair.
How to fix the Windows BitLocker recovery error
In simple terms the only way to fix the issue that emerged alongside the Windows KB5058379 update is to download the new out-of-band emergency patch, which is exclusively found on the Microsoft Update Catalog.
As you can imagine though, the trouble with that is that you need to have access to your PC in order to download and install the patch, and anyone affected by the issue is likely completely locked out.
Thankfully Microsoft have issued a step-by-step process that you can follow in order to temporarily circumvent the issue and access your PC in order to download the emergency update, and it is as follows:
- Temporarily disable Intel VT for Direct I/O (also known as VTD for VTX) and Intel Trusted Execution Technology (TXT) in your BIOS / UEFI settings
- Entering the BIOS / UEFI settings menu depends on your motherboard, but it's typically done by rapidly pressing the 'DEL', F2, F10, or F12 keys during the start up process
- Once you've done that, you should be able to download the new update (KB5061768) from the Microsoft Update Catalog
- Restart Windows, return to the BIOS / UEFI settings menu, and re-enable the previously disabled Intel settings
You will need to enter your BitLocker recovery key in order to do this though, so if you don't know this Microsoft have a specific page to help you find out what it is.
If you haven't yet installed the previous Windows update that is causing the error and you're on an Intel vPro processor, Microsoft has recommended that you go ahead and download the emergency update instead and that should mean that you avoid any of the issues plaguing other users.
