Windows 10 Mobile / Are partitions locked somehow?

[Dz3n]

I don't have access to Off Topic Discussions, so why not to post this here?

So, I have official™ emulator's vhd with Windows 10 Mobile OS.



Looks nice, but I would like to edit/read some data in this VHD. So, I mounted VHD using diskpart, as usual, and there appeared some partitions:


I remember the good old days when I could replace the system files in Windows CE. Well, I know, since WP8, OS uses the Windows NT kernel. This is good as for me, but I remember how I edited the system files in Windows 7, which is also NT. Well, it's just Microsoft's opinion, it's better to hide access from users to file system, but why I cannot access files on this virtual hard disk even when it is mounted?



If I try to do something (even open) to resources, this error will appear

Error 0x80070780: Couldn`t access file

What is the funniest, I still have full access to small files:


Could anyone explain how to access other files?

UPD:
So, Windows asked me to check Data and MainOS partitions for errors. This time I allowed it, and it found a lot of errors.

It's something about removing file attributes.

UPD: Files are still inaccessible.

It's strange. Because I have full access to all files on a real Windows 10 Mobile device through Mass Storage Mode. I'm not sure what will happen if you try to access & modify the VHD file through tools like DiskGenius and/or PartitionGuru.
