<p>Does anyone know the API call I can use to change the keyboard layout on a windows machine to Dvorak?  Doing it through the UI is easy but I'd like to have a script that I can run on new VM's to automate the process.  </p>

You can do this via the registry.  Just save it as a .reg file, and open it on the new VM.  I believe this should do it for remapping to Dvorak:
```
```
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"ScanCode Map"=hex:00,00,00,00,00,00,00,00,22,00,00,00,2d,00,30,00,24,00,2e,00,\
11,00,33,00,33,00,11,00,12,00,20,00,34,00,12,00,1b,00,0d,00,0d,00,1b,00,16,\
00,21,00,17,00,22,00,20,00,23,00,1a,00,0c,00,2e,00,17,00,23,00,24,00,14,00,\
25,00,31,00,26,00,35,00,1a,00,30,00,31,00,13,00,18,00,26,00,19,00,2f,00,34,\
00,28,00,10,00,0c,00,28,00,19,00,13,00,18,00,1f,00,1f,00,27,00,2c,00,35,00,\
15,00,14,00,22,00,16,00,25,00,2f,00,10,00,2d,00,21,00,15,00,27,00,2c,00,00,\
00,00,00
```
```
And if you want to go back:
```
```
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"ScanCode Map"=hex:00,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00
```
```
