Hidden program showing a virtual keyboard on a touchscreen computer and limiting access to several Windows functions. It can popup a password protected administrator menu for accessing tools and settings.
It uses the free virtual keyboard FreeVK (http://www.freevirtualkeyboard.com/) and a 3rd party taskmanager (https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer) as the Windows taskmanager had been disabled by policies.

| - | Disables the header bar of FreeVK. Because of this the configuration and close/hide buttons on the FreeVK window are not available for the user |
| - | Checks every second if the FreeVK window is not closed or hidden and brings it back |
| - | Optionally disables in the StartVK.ini file configured keypresses |
| - | Optionally starts a configured application at startup and/or by keypress |
| - | Redirects a configured keypress to an other (comes in handy if you need e.g. the PgDn button wich is unavailable in FreeVK) |
| - | Starts up to 4 programs with configured keypresses |
| - | Opens a password protected Admin panel by a configured keypress |
| - | Start Sysinternals Process Explorer and optional program from the Admin panel |
| - | The optionally disabled keypresses can be enabled in the Admin panel |
| - | As from v1.91 an optional mouse jiggler was added to prevent the computer to lock |

We needed to limit access to almost all Windows functions and start a virtual keyboard on a bunch of touchscreen computers. This project began searching for a suitable virtual keyboard as the Windows 7 virtual keyboard did not suffice. The free virtual keyboard FreeVK was the best I could find but it did have a header where the configuration of the keyboard could be altered. I didn't want the users to mess with the keyboard settings so was looking for a way to hide the header.
With AutoHotKey it is fairly simple to alter standard Windows applications on the run so I created a script that hides the header from FreeVK and also checks every second if the keyboard is still active. If not it restarts FreeVK.
The size and position of FreeVK can stil be altered (allthough its takes some effort on a touchscreen). The active settings can be saved from the StartVK admin panel and restored whenever needed.
Most access to Windows functions and shortcuts can be disabled by policies but some you do not want to loose for administrator use. Therefor I expanded the abbilities of StartVK by capturing configurable keypresses. Now all Windows keyboard shortcuts are blocked as is the right mouse click. In addition StartVK can alter keypresses as some keys (like PgDn) are not available on the virtual keyboard.
In version 1.7 an option was added to start an extra application automatically and/or manual by a key combination. This was added for StartVK to control WeightKey but it could be any program you need.
