See if you have this registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\NonEnum
and see if the following entry in the right panel:
{645FF040-5081-101B-9F08-00AA002F954E}
If it is, and the data is set to 1, set it to 0 . This causes Recycle Bin
to be Hidden/Shown (1/0).
If not, check this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}
and see what is set for SortIndex (should be hex 0x60).
