Windows 10: Windows update triggered bitlocker twice within a week... Why

Last week my Lenovo did a Windows update and it triggered the bitlocker... Had some it friends look at it and the hard drive was toast... We replaced the hard drive and reloaded windows... Tonight it updated again and once again triggered bitlocker.... Why is it doing this? Fortunately it reloaded windows but this is ridiculous. Is there a way you avoid this?

Automatic windows update with BIOS update triggered bitlocker

Hello Debra Delacroix,

thank you for posting on the Microsoft Community Forums.

An automatic BIOS update during a Windows update can potentially enable BitLocker or trigger a BitLocker recovery if certain conditions are met. This is especially likely if the update changes hardware configurations or settings that BitLocker monitors to ensure system integrity. Here are a few steps you can follow given your situation:

Step 1: Verify BitLocker Status.



1. Access Windows Recovery Environment (WinRE):

- Power on your computer and as soon as the Windows logo appears, hold down the power button to force shutdown. Repeat this process 2-3 times until you see the "Preparing Automatic Repair" screen.

- After diagnosis, go to "Advanced options."



2. Use Command Prompt in WinRE；

- Navigate to "Troubleshoot" > "Advanced options" > "Command Prompt."

- In Command Prompt, type the following command to check the BitLocker status:

This will show whether BitLocker is indeed enabled and on which drives.

Step 2: Look for the Recovery Key in Alternate Locations.

You need to follow the steps in Finding your BitLocker recovery key in Windows - Microsoft Support to find it out.

Important:

• If you are unable to locate the BitLocker recovery key and can't revert any configuration change that might have caused it to be required, you’ll need to reset your device using one of the Windows recovery options. Resetting your device will remove all of your files.
  
• Microsoft support is unable to provide, or recreate, a lost BitLocker recovery key.
  

Step 3: Change BIOS/UEFI Settings.

1. Disable TPM:

- Restart your computer and enter the BIOS/UEFI settings (usually by pressing a key like F2, F12, Del, or Esc during startup).

- Navigate to the security settings and look for TPM (Trusted Platform Module).

- Disable TPM and save changes, then restart your computer.

Step 4: Other Options.

1. Safe Mode:

- Attempt to boot into Safe Mode by holding the Shift key and selecting Restart from the power menu. If you can access Safe Mode, there might be administrative tools to disable BitLocker.



2. Try Automated Recovery:

- In the WinRE, go to "Troubleshoot" > "Advanced options" > "Startup Repair." Follow the prompts to see if Windows can fix the startup issue automatically.

Final Option: Clean Installation.

If no recovery key is found and you cannot disable BitLocker, performing a clean installation of Windows might be your last resort.

Regards,

Lei

Task scheduler On Idle task not triggered Windows 7

Windows 10: I've just tested on windows 10 and set the task idle time to be 5 mins, but it
still triggered after 4 mins only, I've manually timed it 3 times and always triggers after 4 mins not 5 mins, any idea why?

Windows 7: Isn't the task triggered because Windows 7 does not admire the 4 minute idle timer as
according to Microsoft Windows 7 checks if the system is idle every 15 minutes? if so then shouldn't it work if the task idle time is set to 20 mins for example?

UPDATE : I just tested it and manually timed it twice on my Windows 7 machine and it always triggers after 15 mins of Idle time even if I am setting the Idle task to 20 mins. Also my
application doesn't start although the task is triggered but instead of my application running a screensaver starts running although I am setting screensaver to off on my machine. Any explanations or advice please?

WMI suggestion: Could you advise with the steps step by step to follow to do you WMI suggestion
please?
