Develop a menu-driven batch script (DOS/WMI/Powershell script) which works on Windows 10

Requirements of the script:

A script which mounts and dismounts the
encrypted container

A script which sets and removes VERAPATH
and VERAPASS

A script which does (1) by checking for the
existence of a sentinel and either mounts or
dismounts an encrypted container.

The script displays a set-up menu and uses
this to call the find, input and remove scripts

All scripts combined in one file, and no errors
are generated.

The script must not:
The script deletes or corrupts the local user
%PATH% variable

Major errors which prevent code execution or cause
a crash

Code not written for Windows 7-10 or requiring the
installation of other scripting languages (e.g. python)
