We have a number of users with Windows Mobile 6 and need to apply minor changes. eg. update a registry setting. One option is push and execute an executable file using our devic
Try Lua:

Lua WinCe / Mobile port: http://www.magma.com.ni/sw/wince/lua/
Once option that the devs over at xda-developers seem to enjoy is Mortscript
I have never bothered to use it, but I have used many cab installers that distribute mortscript so that they can do various tasks
The closest thing to a scripting environment on Windows Mobile is the Configuration Service Provider interface. While it is not a scripting language per se, it does allow one to do a lot of the same type of things such as modify registry settings, copy and delete files and directories, install and uninstall applications and much more.
Mike Calligaro has a great article on how to write scripts and how to get them from your desktop onto the device in various ways. One of them is certain to work for you.
I work on windows mobile full time and have never really come across a good Windows Mobile scripting implementation unfortunately. For some reason MS has never seen the need for it. For example, even though you can actually get a command console on WM, it does not support running batch files, even though all the commands are still there and it would be relatively easy. There is definitely not a VBScript engine I've ever heard of nor JScript. There is PythonCE but the WM specific support is minimal and you don't get access to a lot of WM only things.
Also, I've done a lot of work with a company called SOTI which has a product called MobiControl that does incorporate a basic scripting engine. Though most of the commands are specific to their system and actually have to be run from a desktop-side management console.
Given all of the times I have tried to find a good scripting engine for WM myself you would think I would've just written one ;)
So, sorry, but the basic answer is no, there is not a scripting engine available for VB in the context that you specified.
There is also a Visual Basic Runtime to run VBScript
