Windows 10: Bitlocker bypassed when restarting after windows update

I have a notebook running Windows 10 Pro (without TPM).


When I power on, I am brought to the Bitlocker password screen, as expected.


However, when requested to restart after some Windows updates, Bitlocker screen is bypassed and I'm brought to the Windows logon screen. This does not happen with all update/restarts, but seems to be random.

Broken security by bypassing lock screen on restart

Question:

Why does Windows bypass the lock screen when it restarts after a Windows update? I consider this a security design flaw. If a maintenance crew came by my home while I'm at work to do some home renovation upgrades but they left the
front door unlocked when they finished, when I got home I'd wonder what on Earth they were thinking. I hope I've just missed a setting somewhere to disable this.

Three things I accept:

1. Locking my computer to protect my privacy.

2. Windows restarting after an update.

3. Windows automatically updating, which is frustrating but acceptable.

But I don't accept Windows bypassing the lock screen after an update.

Precondition:

Windows 10 is set up to require a password at sign in, both on startup and on the lock screen.

Steps to reproduce:

Step 1: Lock the computer.

Step 2: Leave the room.

Step 3: Wait for Windows to perform an automatic system update.

Step 4: Windows restarts automatically.

Problem 1: Windows bypasses the lock screen, instead signing in and showing the desktop.

Problem 2: Come home and book a doctor's appointment to deal with the stress of seeing my computer unlocked.

It's my first post in the community so suggestions about posting etiquette are welcome.

 

BitLocker - Is it possible to bypass on Restart?

Hello, just wondering, if you have BitLocker on is there a way to stop it asking for password/PIN when you restart the computer?

Restart ONLY

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.


Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
