I don't think you can put it in a users login script because hosts may be protected... Unless user is an admin.<br />
<br />
You could put it in a gpo in the Startup script, which should work.

Keep in mind this will need to happen with elevated user permissions on most modern versions of Windows.<br />

How to add an entry with a condition to hosts file?

VBScript (Visual Basic Scripting Edition) is an interpreted scripting language developed by Microsoft that is modeled on Visual Basic, but with some important differences. VBScript is commonly used for automating administrative and other tasks in Windows operating systems (by means of the Windows Script Host) and for server-side scripting in ASP web applications. It is also used for client-side scripting in Internet Explorer, specifically in intranet web applications.

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Batch files are text files containing a script of commands that are executed by the command interpreter on DOS, OS/2 and Windows systems. Most commonly, they are used to perform a series of functions that are repeated -- copying a set of files created daily with one step, for example.

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.

The term 'shell' refers to a general class of text-based command interpreters most often associated with the UNIX and Linux operating systems. Popular shells include Bourne, Debian Almquist (dash), Korn (ksh), Bourne Again (bash) and the C shell family (csh). Some view the DOS 'cmd' prompt as a minimal shell of sorts. It is also possible to install Cygwin on Windows and emulate a full Unix environment with complete shell capabilities. Terminal emulators, such as xterm, GNOME Terminal and OS X Terminal, can be used to access shell.
