BitLocker screen awfully slow after Windows 11 24H2 update

[JensDe]

Hi community!

Since I installed Windows 11 24H2 update on my brand new machine, the Bitlocker screen during boot up is awfully slow. The screen is shown during boot and I need to enter my PIN here.

The problem is: Since the update the screen takes ages to build up. Roughly 1 line per second and I need to wait until the whole screen is build up before I can enter my PIN and proceed.

Microsoft seems not to be able to solve the issue on their side. Does somebody from the community have any idea how I can solve this issue? I

Hi @JensDe,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The slow BitLocker PIN screen issue after the Windows 11 24H2 update could stem from a few factors, including drivers, firmware, or system configuration changes introduced by the update. Here are some steps you can take to resolve or mitigate the issue.

Update BIOS/UEFI Firmware

• Visit your laptop manufacturer’s support website and check for any available BIOS/UEFI updates. Firmware updates often include optimizations for boot processes and hardware interactions, which might resolve the issue.
• Follow the manufacturer's instructions carefully while updating the BIOS.

Update Storage and Graphics Drivers

• Outdated or incompatible drivers for storage controllers or graphics could slow down the rendering of the BitLocker screen.
• Update drivers via:
  • Windows Update: Settings > Windows Update > Advanced options > Optional updates.
  • Manufacturer's Website: Download the latest storage and GPU drivers specific to your laptop model.

 Switch to Software BitLocker Encryption

• If your system uses hardware-based encryption (common with SSDs), compatibility issues with the new Windows version might cause delays.
• Switch to software-based encryption:
  1. Suspend BitLocker: Open Control Panel > BitLocker Drive Encryption > Suspend Protection.
  2. Disable hardware encryption:
     • Run gpedit.msc to open the Group Policy Editor.
     • Navigate to: Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives.
     • Enable the setting Use software-based encryption when available.
  3. Resume BitLocker: Reactivate BitLocker protection.

Disable Fast Boot in UEFI Settings

• Fast Boot can sometimes interfere with boot sequences, including the BitLocker prompt.
• Access the UEFI settings (usually by pressing Esc, F2, or Del during startup) and disable Fast Boot.

Use a Simplified Boot Mode

• If your laptop supports Legacy Boot Mode, you can test whether switching from UEFI to Legacy improves performance. Note, this might not be possible on all systems with secure boot and BitLocker enabled.

Test with Minimal Peripheral Devices

• Disconnect any non-essential peripherals during boot to ensure they aren't causing delays.

Repair BitLocker Configuration

• Reset the BitLocker TPM PIN interface using the following steps:
  1. Open Command Prompt as Administrator.
  2. Run:

manage-bde -protectors -disable C:
manage-bde -protectors -enable C:
 

1. Reboot and test the boot screen performance.

I hope this helps.

Take care and have a good day.

Good Morning,

Thank you for your helpful solutions. Unfortunately, none of them worked. This problem only occurs with the HP 440 G2 model. In our company, we have other devices from brands like Dell and Fujitsu, and none of them have this issue.

Best regards,

Gonçalo
