Win10 on Win10 Shared folders have ceased working

I have a Win10 x64 VM running on Win10 x64 host. Virtualbox is v5.0.10. Since the Win10 cumulative update to version 1511 earlier this week (on both host and VM), my Win10 VM can no longer see the shared folders on the host that could be accessed before the cumulative update. I also have a Linux Mint VM on the same machine that has exactly the same host shared folders configured, and it can still see the shared folders, so the problem would seem to be on the Windows VM side rather than the host side. Any suggestions? When I Iook in the VM log, what I see there indicates that the shared folder was added correctly:

Code: Select all

00:00:05.237070 SharedFolders host service: Adding host mapping
00:00:05.237087     Host path 'D:\Users\Nick\Downloads', map name 'Downloads', writable, automount=true, create_symlinks=false, missing=false
00:00:05.238203 Changing the VM state from 'CREATED' to 'POWERING_ON'

remove the shared folder from the guest- restart the guest - reinstall the guest additions - add the shared folder - restart the guest.

Same issue today after upgrading Guest Win 10 to 1511 (November Update).
Nope, removing, restarting and readding didn't help.
I removed every mention of a shared folder from both Host and Guest, restarted everything, re-added the shared folder in the virtualbox, trying to set up in Guest again and the same thing, can't find the path.

Boom! Reinstalled the VB guest addons and the shared folder reappeared after the reboot. :)
