Do you want to run your old DOS games on your computer that installed Windows XP system Or learn how to program under GNU/Linux, without leaving your Windows desktop Want to run multiple operating systems on one computer for different purpose Yes, you get it! The virtual PC operating system software can realize your needs. At it happens there are some powerful yet easy to use Virtual PC operating system software I will show you. They are: Virtual PC for Windows, Connectix Virtual PC for Mac, Returnil Virtual System and VMware Server. Come on with me and see if there is a favorite virtual PC operating system for you now.

Virtual PC for Windows allows multiple operating systems to run concurrently on a single machine. It enables developers to test and debug their software on a number of different platforms, all on one PC. Other uses include training, tech support, legacy application support or any other use that requires access to multiple operating systems. We can easily switch between operating systems without having to log off or reboot. Virtual PC for Windows is a virtualization suite for Microsoft Windows operating systems, and an emulation suite for Mac OS X on PowerPC-based systems. Virtual PC virtualizes a standard PC and its associated hardware. Supported Windows operating systems can run inside Virtual PC. However, other operating systems like Linux may run, but are not officially supported.

Connectix Virtual PC for Mac delivers true PC compatibility by enabling our Mac to run Windows applications, access PC networks, use Windows-only Internet applications and share files with PC-based colleagues. Virtual PC provides us with the functionality and compatibility of a Pentium PC through sophisticated software emulation of the standard Intel chip set and other hardware components. It's like putting a powerful PC inside our Mac. We can run our Windows or DOS software - including business, education, Internet and home applications - just as we would on a PC. Let's face it, we love our Mac but sometimes we need the ability to run Windows applications. With Virtual PC we can now emulate an entire PC without any additional hardware costs. Virtual PC lets us run one or more fully functional, emulated PCs on our Mac and is compatible with a full range of Windows operating systems, as well as DOS. We are limited only by our current machine's RAM and disk space.

Returnil Virtual System is a powerful virtualization technology that completely mirrors our actual computer setup and it can create a virtual storage disk within our PC where we can save documents, data, and files while using the System Protection feature. The security of computers connected to the Internet remains a problem. Despite the efforts of major Anti-malware companies, a high proportion of computer infections remain undetected, Internet crime continues to grow and new malware is being discovered at the rate of many tens of thousands of items per day. The situation is getting worse, proving that existing security technologies, whilst useful, are inadequate. Returnil virtualization technology clones a computer's System Partition and boots the PC into this system rather than native Windows, allowing us run our applications in a completely isolated environment. Hence the session and all activity, malicious or otherwise, will happen in the virtual environment, not in the real PC environment. If the PC is attacked or gets infected, all we need to do is to simply reboot the PC to erase all changes. After reboot, the system will be restored to its original state, as if nothing ever happened. All of this without sacrificing computer performance or usability while helping to reduce technical support intervention and the need for routine maintenance. The Returnil Virtual System provides the third and arguably most important part of a true layered approach, the cure! Stop the endless, performance hogging cycle of filtering, detection, and removal. We can finally sit comfortably and start enjoying our computer.

VMware Server provides two free virtualization software. VMWare Player allows us to use virtual machines created by other software (such as VMWare Server, Virtual PC or the free third-party command-line VMX-Builder). It allows us to run operating systems like Linux, Windows, FreeBSD, etc, on top of our existing Windows or Linux system. VMware Server allows us to create and use virtual servers. The site also provides a number of prebuilt virtual machines for free operating systems (like Linux), including something they call a "browser appliance" - a complete system running under their virtualisation software (VMWare Player or others) that allows us to surf the Internet safely without jeopardising our main machine even if our browsing leads us to unsafe sites. Instead of cleaning up our machine with an antivirus program or an anti-spyware software, we simply ditch the changes made in the virutal machine and restart it.

In a word, Virtual PC for Windows is a classical virtual PC operating system. It enables developers to test and debug their software on a number of different platforms, all on one PC. Connectix Virtual PC for Mac provides us with the functionality and compatibility of a Pentium PC through sophisticated software emulation of the standard Intel chip set and other hardware components. It's like putting a powerful PC inside our Mac. Returnil Virtual System is a powerful virtualization technology that completely mirrors our actual computer setup and it can create a virtual storage disk within our PC where we can save documents, data, and files while using the System Protection feature.

After reboot, the system will be restored to its original state, as if nothing ever happened. VMWare provides two free virtualization software. VMWare Player allows us to use virtual machines created by other software. VMware Server allows us to create and use virtual servers.
