Citrix and Server 2012 legal notice scrollbar

If you have a Citrix XenApp/XenDesktop 7.x environment and enabled the legal notice and you are seeing the legal notice being displayed in a window with scrollbars here’s the solution.

On the XenApp/XenDesktop machines add these registry keys:

For 64bit VDA:
HKLM\Software\Wow6432node\Citrix\CtxHook\AppInit_DLLS\Multiple Monitor Hook\LogonUIWidth = DWORD:800
HKLM\Software\Wow6432node\Citrix\CtxHook\AppInit_DLLS\Multiple Monitor Hook\LogonUIHeight = DWORD:600

For 32bit VDA:
HKLM\Software\Citrix\CtxHook\AppInit_DLLS\Multiple Monitor Hook\LogonUIWidth = DWORD:800
HKLM\Software\Citrix\CtxHook\AppInit_DLLS\Multiple Monitor Hook\LogonUIHeight = DWORD:600

The size can be changed to different values as you see fit and based on the size of the legal notice.

Cheers,
Jack
