Bug: Mounting VHD files with Bitlocker may cause an issue that can't access it

[Xionghaizi001]

Description

When using Files to mount a VHDX file containing BitLocker, a UAC dialog pops up, but nothing happens. The file is actually mounted but remains unlocked. If you attempt to mount it again, you won’t be able to access its files, and Disk Manager will display an "unknown" partition with BitLocker.

Steps To Reproduce

1. A VHDX file contains 1 or more partitions encrypted by Bitlocker;
2. Mount it;
3. Hold on a second;
4. If not require to input password, double-click VHDX file again;
5. Reproduced.
6. (Optional) Open Windows explorer and click the partition in VHDX -> "Parameter error";
7. (Optional) Open Disk Manager -> Unknown partition (Bitlocker enabled)

As I mentioned in the comment, nothing visible will happen, but you won't be able to access your VHD unless you reboot Windows.

I'm asking what happens if you mount the VHDX in Windows File Explorer, If it does the same as Files then it better send as Windows Feedback

Sorry, I misread your comment. When mounting it in Windows Explorer, the system normally asks me for the password, and nothing happens if I ignore the popup. If you click the file again, Windows will show an error that requires you to unlock it.
