Best is to use Samba share on windows, and connect to it on Linux VM.

1: Share Folder From Command Line in Windows net user guest /active:yes net share vagrant /DELETE net share vagrant="%CD%\projects" /GRANT:Everyone,FULL /REMARK:“Shared dir for Linux box” Icacls “%CD%\projects” /grant Everyone:F /inheritance:e /T

2: Networking between host and guest VMs in VirtualBox Mount A Network Share On Linux / Ubuntu | LINHOST.INFO

apt-get install cifs-utils

mkdir /mnt/vagrant
mount.cifs // /mnt/vagrant -o user=vagrant,pass=vagrant

or like this:
    mount.cifs //  /mnt/vagrant -o user=,pass=

echo "// /mnt/vagrant cifs username=dummy,password=dummy 0 0" >> /etc/fstab

And it works.

E: Cannot allocate memory

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v LargeSystemCache
reg query "HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" /v Size

Change the values with:

reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /f /v LargeSystemCache /t REG_DWORD /d 1
reg add "HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" /f /v Size /t REG_DWORD /d 3
