* Checks if password exists for the user, if it doesn't the user is prompted to create one.
It checks if the password is equal to $null using `ValidateCredentials` and if it isn't the variable will be created. If it is equal to $null, a window with text, a textbox and a button will appear asking the user to create a password. That password is then set for the user and the winget installation continues.

Securing the password variable when it gets created and deleting it after it's done being used.
* Forces the user to input their password and automatically puts their username into the credentials box
* Removed the second greater than 0 check
