You can't copy and paste files between a system that is running Virtual Machine Connection (VMConnect.exe) and a Hyper-V guest virtual machine when you use Enhanced Session Mode through Remote Desktop Protocol (RDP).
Enhanced Session Mode enables the transfer of files to and from virtual machines through the Clipboard copy-and-paste operations. However, copying and pasting files through the Clipboard is disabled if the Do not allow drive redirection policy option is enabled.
To successfully copy files to and from Hyper-V virtual machines when you use VMConnect through Enhanced Session Mode, make sure that you don't enable the following policy:
Policy path: Computer Configuration\Policies\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Device and Resource Redirection
If you use the Local Group Policy Editor, the Policies folder is not part of the node path.
Policy setting: Do not allow drive redirection
Set this policy to "Disabled" or "Not Configured" to allow file copy redirection in Remote Desktop Services and Hyper-V Enhanced Session Mode sessions.
