Why Virtual Machine Why is it necessary to run two, three or

more operating systems on one computer?

flexibility

Benefits Ease of use;

Users may switch between operating systems and applications with the click of a mouse — without Repetitive rebooting and relaunching.

Affordability; one computer becomes capable of running multiple

operating systems, applications and services. Security;

Operating systems and applications running within a virtual machine may be "cut off " from other environments.

Benefits Safety;

Changes to virtual machines do not affect the day-to-day Windows environment and changes that might be catastrophic within a virtual environment may be discarded when no longer needed.

Legacy support; Users may upgrade to new hardware and operating systems, yet

virtual machines maintain the ability to run older software that would otherwise crash in the new environment.

Standardization; avoids bugs caused by minor differences between PC hardware

systems. Configurability;

This allows users to create a wide variety of testing environments.

Benefits Guest operating system flexibility;

Virtual PC supports a wide variety of x86 operating systems. Easy Installation;

Convenience; All virtual machines, whether running, suspended or saved, are

managed through a single convenient user interface. Host Integration.

Integrating applications makes interoperability between the guest and host operating systems a snap.

Applications Technical Support

Enable an entire department to be backwards compatible even while upgrading to new hardware and operating systems that would normally cause your legacy applications to crash.

Set up any number of user-specific system configurations, on a single computer for real-time scenario testing and evaluation.
