This is a quick explanation of how Kidaro helps, and what it looks like to end users:
At a basic level the technology provides enterprise application-to-OS compatibility. We can assist customers in their migration to Windows Vista while supporting legacy applications in a virtualized Windows XP environment through the seamless use of Virtual PC technology. Think about this technology as providing management support and ‘steroids’ to Virtual PCs.
The OLD WAY of using Virtual PC on Windows:
Standard virtual machine interfaces require users to manage two desktops, two start menus, and two taskbars.
The NEW WAY of using Virtual PC on Windows:
With Kidaro Administrators can centrally define a set of applications to be installed in the virtual machine workspace. These applications will be available directly from the user’s start menu. Kidaro’s Single Desktop experience ensures a familiar user experience, making virtualization practical for deployment across large user groups with minimal training.
Workspace applications are integrated into the desktop, appearing side by side with native applications. A colored border is used to designate workspace applications on the desktop, and the virtual machine operating system and desktop are invisible to the end user.
