Documents (system folder) restore default

[stuck]

Win 10 Pro, v1709 build 16299.125

1) In Explorer I selected the 'Documents' folder, i.e.:
    C:\Users\\Documents

2) I right clicked and then clicked 'Properties'
and then selected the 'Location' tab
and then clicked 'Move'
and browsed to the second HDD (drive D)

3) The move went OK BUT I made mistake and instead of making 'D:\data' the 'Documents' folder I've made the whole drive, i.e. 'D:\' into the 'Documents' folder.

4) OK, that was careless but all I need to do is use the 'Restore Default' option and then redo the move

EXCEPT when I try that a dialog box appears saying:
The folder can't be moved here
Failed to build the list of regular subdirectories under "D:\System Volume Information".
Access is denied.

There is only one user on this PC and it is a member of the 'Administrators' group so in theory it has full access to everything. However, the HDD was pulled from my XP box, where 'D:\data' had similarly had been set as the 'My documents' so I'm wondering if part of the problem is that the "D:\System Volume Information" folder contains XP data.

Any clues?

I suspect REGEDIT may be your friend. Search for D:\ and you should find the relevant entries.

Another thought. Maybe it is trying to move EVERYTHING under D:\ down to D:\Data\, and it tries to move D:\System Volume Information as part of the move. In that case you could probably use the UI to move the pointer, specifying that the documents should NOT be moved. Then manually move the documents to the new location.

Thank you Stuart. Yes, REGEDIT was the answer, I thought of that as soon as I posted ( Lounge Magic^TM).

Searched the registry for 'D:\' and it found relevant keys under:
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

Modified them, rebooted and all is well again.
