+Windows uses this to determine what kind of file it is to execute. Additionally,
+if you are running Vagrant on something like Cygwin or WSL where bash is
+available, then you should be able to use an extension like ".sh".

+```ruby
+Vagrant.configure("2") do |config|
+  config.vm.provision "shell", path: "scripts/PowershellScript.ps1"
+end
+```
