HP Recommended
Operating System: Microsoft Windows 11

HP Accessory Center 2.21.4522 interferes with BitLocker on my Windows 11 26H2 machine (also valid for 25H2). 

 

Steps to reproduce:

1. Open HP Accessory Center

2. Connect a BitLocker-encrypted external SSD

3. Unlock the encrypted SSD by entering its password

4. Try to open the drive.

 

Result: an error appears

Expected result: the drive is opened

 

This doesn't happen if the HP Accessory Center is not started. The program holds an open handle to the RAW volume before it's mounted (when the password is entered), which prevents Windows from properly mounting the NTFS partition once BitLocker password is entered.
