Above suggestions didn't worked for me. I got it running on my windows, using inspiration from http://butlerccwebdev.net/support/testingserver/vhosts-setup-win.html
For Http inside httpd-vhosts.conf
<Directory "D:/Projects">
AllowOverride All
Require all granted
</Directory>
##Letzgrow
<VirtualHost *:80>
DocumentRoot "D:/Projects/letzgrow"
ServerName letz.dev
ServerAlias letz.dev
</VirtualHost>
For using Https (Open SSL) inside httpd-ssl.conf
<Directory "D:/Projects">
AllowOverride All
Require all granted
</Directory>
##Letzgrow
<VirtualHost *:443>
DocumentRoot "D:/Projects/letzgrow"
ServerName letz.dev
ServerAlias letz.dev
</VirtualHost>
Hope it helps someone !!
