What is windows Virtual PC?
Windows Virtual PC is the virtualization program especially made for the Microsoft windows and act as the virtual PC which virtualizes the associated hardware components with the PC suite and act as the successor for the Microsoft Virtual PC 2007, Microsoft Virtual PC 2004 and connectix Virtual PC and work as the windows hosted product of free license and do not work on operating system earlier than windows XP SP3 Professional and it sometimes may work in Linux also but not fully because Microsoft does not release official drivers for the Linux operating system. It is only compatible with the window 7 hosts only.
Publicly, windows virtual PC was introduced as the public beta on 30 April 2009 which was few days after window 7 release. when it is released it was meant with few restrictions such that hardware virtualization support is required in case you want to work it but later after the 19 March 2010 Microsoft has provided a updation tool in it according to which you can update the Microsoft Virtual PC and run it on every PC without any hardware support which is the great boom for the windows virtual PC.
Improved Features of Windows Virtual PC
The windows virtual PC is the desktop sharing software tool used for the virtualization and its improved features are discussed as follows-
Windows Virtual PC is available free of charge for the various editions of window 7 and you can even download it from Microsoft official website. Moreover, the USB support is also there in it according to which you can connect and redirect as many peripherals devices as you want which specify there categories as flash drives, slot for the digital camera, printer applications that connect guest to host and data cables of mobile phones or the other audio or video players. Instead of this the devices which is not synchronous with the USB ports such as webcams, microphones are not supported by it because of the reason that the audio or video streams in this devices does not vary with the time, as it time varies during the operation of execution. Thus, it creates problem for the port devices to receive and send the signals exactly at the fixed time intervals, so fully integrated support for the synchronous devices which is fulfill the criteria of the fixed time streaming of the signals and applications.
Windows XP Mode
You can even launch the publishing and launching of the window XP application under window XP mode by using the window 7 desktop which act as the virtual machine package for the windows virtual PC that contains the pre-installed copy of the windows XP professional service pack 3 which is a guest operating system, the newly update Microsoft tool has removed the dependencies of the CPU and motherboard for hardware virtualization and provide the pre-installed integration of the of the components which allows the applications to be run under the virtualized environment which appear directly to the host by sharing the local desktop of the windows 7 with the start menu of associating files by combining it with the windows terminal services which maintains the session with the window XP such that window XP mode can be directly accessed with the help of the Remote Desktop Protocols using the client running of the host operating system that is window 7.
It removes all the compatibility issue that may occurs when you are forcing an application to run under the window XP mode because it internally registered its entry in the window XP virtual machine and redirect the RDP to the window 7 for the 64-bit transfer of the data using the data bus or the address bus and compatibility of it even reduces less than it by running the 16 bit applications too. Moreover, you can even run the versions Internet explorer versions concurrently under the windows XP mode.
Windows virtual PC support Multithreading which can run two virtual machine concurrently using the improved stability and performance of the system such that hardware support is there to efficiently execute multiple applications using the concept of multi-processing systems which uses multi core processors that share the resources of the single core processor with the same computing units, CPU caches and translation lookaside buffer, the main of which is to utilized the resources of threading level and instruction level parallel with each other so that the applications can be shared with multiple resources instead of using the individual resources, thus it reduces the overall cost of the devices required for operation. Moreover, increases over all performance of the system such that in case one thread misses the cache then the other thread can continue the advantage of the computing resources which lead to the faster execution and synchronization of resources.
When a synthetic program of Hyper threading is using the loop of non optimized dependent operating points then it can gain the speed of 100 percent and while on the other had switch itself to the assembly language programs using the MMX or altivec extensions that fetches encoding and don not miss the idle computing resources and thus reduces the degraded performance due to the contention of the shared resources. The goal of threading is to quickly switch between the blocked thread and another thread which is ready to run and this can be done in one CPU cycle and minimizes the amount of software’s required for the execution. For example-Microcontrollers and embedded processors has multiple register bank which allows the quick switching for the interrupts after making the scheduling of the various processes which are being in state of execution.
Smart card redirection
The smart cards or the chip cards which are embedded in the integrated circuits and of pocket sized consist of the memory cards which contain only volatile memory storage of the resources and fully dedicated to the storage of the logical operations and the others are microprocessor cards which also consist of the volatile memory and other processor components for providing the sign-in and security authentications especially for the large firms and organization which carry a large amount of the data and thus windows virtual PC redirects the smart cards to easily connect the PC to the host computer.
The smart cards are basically used in the health insurance and exactly same as the credit cards and debit cards which has separate uniquely identified key codes which is often referred with the name of pin number and it will then redirect the user to the desired location therefore it is known with the name of administration system which will configure the login information for the access of the individual accounts by identify the unique password along with authentication of the data processing and data storage. Moreover, the volume of information are programmed by the card with multiple banking credentials that has embedded in its coding to offer free and easy transactions that provides the gain to the necessary funding when required.
The windows virtual PC makes use of the dynamic compilation only to translate the x86 kernel mode and real mode code into x86 user mode code, the final x86 user mode code make use of the virtual 8086 mode to run the program locally that traps the guest calls to accelerate additional features to integrate wit the host environment to encapsulate the virtual server with the virtual hard disks file format and the documentation of all these processes are carried out under the open specification promise. Instead of this, a virtual switch is also there in the virtual environment to allow the adding of the multiple network adapters.
Supports host and guest operating systems
The multiple guest operating systems can run the virtualized processes in a single physical host by making use of the windows Virtual PC such that a large number of hosts can manages the guest using the core virtualization which provides the running of the many operating systems after testing them properly and provides full support to the customers who encounters problems while running these operating system, as a desktop use, it supports a set of operating system which support the server oriented counterpart such that supports only one variety as host and another as guest, for the support of the Linux operating system the concept of the virtual server and Hyper-V has been introduced which can easily run with the Virtual machine additions as the 64 bit host.
System requirements of windows virtual PC
Windows XP mode is freely available in free of charge to the users of windows 7 Professional, Enterprise and ultimate and offers few restrictions as far as the system requirement is concerned which is explained below-
As mentioned above that the it requires the window 7 Ultimate, Enterprise or Professional and does not offers the windows XP mode for the other versions and also the processor should be such that it offers the multi-processing and should be more than 1 Gigabytes that includes the 32-64 bit data processing of various operations using the data buses such as SVGA, VESA graphics card, PCI or 4 MB video RAM with the limit of up to 16 bit MB for the editing of the standard file applications.
The RAM should be more than 1.25 Gigabytes because every process in state of execution requires the allocation in the main memory also due to this fact only that it RAM capacity should be more than it because few windows 7 applications are compatible with the RAM of between the 1 GB to 2GB.Moreover, Ethernet network card is also there to access of the data from host computer along with the hardware opcodes and exotic timings.
The storage capacity of 15 Gigabytes is required which is non volatile in nature because data stored in it doesn’t lost even the power can switched off due to this fact only the capacity for the storage should be more for the user data because windows 7 itself takes a lot of virtual memory for running its own applications, the soft wares and drivers of windows 7 are too much heavy, thus more storage capacity is required to run the windows virtual PC.
The Intel-VT and AMD-V is used for the virtualization of the data which is either a hardware device are mandatory to support the other peripherals devices. For example- if you are using the Intel Pentium II processor and your host machine must use the Intel 440BX chip-set for the virtualization of the hardware. Moreover, the basic input output (BIOS) function must of American Megatrends which creates the labs sound blaster between the hot and guest operating system by synchronizing the audio configuration of the files.
Removed features from windows virtual PC
The Drag and the drop file sharing between the host and guest has been removed but this are now carried by under the supervision of the protocols and TCP/IP model which redefine the path of transmission of files among these machines, the direct sharing of folders may be removed and few restrictions are imposed on the data sharing and the virtual machines actions are cannot be reverted using the undo or commit command in the earlier versions has been removed and now you can make the changes according to yourself.
The parallel ports are removed from the windows virtual PC because it sends the bulk of data on the single life cycle and time clock measurement features is not there in it which is removed now because the action of direct sharing between the host and guest is not allowed in the latest version which is fully compatible with the windows 7, the user interface of the virtual floppy disks functionality is not included in the latest version but when there is an need to access the virtual floppy disk then it make use of the intermediate script which act as the interface between the host and guest.
Integration requirement of virtual components
Using the windows virtual PC, you can make use of the guest and host operating systems to interact and share the common physical hardware components for the exchange of the data with the help of the virtual network interface and sometimes, mouse cursor itself can be used to control the operating system at any given time only if integration components are fully installed in the guest operating system, then it will give rise to the following features which will be activated itself on the details of which is given below-
The mouse can be shared between two machine such that the movement of the mouse can take place between both the guest as well as the host machine and the host computer machine has rights to initiate any external activity that involves the automatic shutdown of the machine using the defined set of application functions which not only shutdown the system but also controls the restart, standby and hibernation under windows virtual PC.
The time synchronization of the control signals should be synchronized automatically with the clock pulses of the virtual machine such that host machine clock should coordinate all the activities of the virtual machine and process the monitoring of the applications takes place using the task manager operator that will detect whether the software on the guest operating system is responsible or not.
The dynamic screen resolution of the guest operating system can be changes either by changing the positions of the pixels or monitoring the position of each and every pixel with the variation of the size of the main window screen on which guest machine desktop is running. Moreover, the audio sharing is also allowed according to which both host and guest machine can also share the common platform of audio activity.
The sharing can be clipboard sharing according to which the text, picture or windows clipboard may be shared between the machines, the smart card sharing which access the authentications and security rights, printer sharing which involves file and printer sharing over a virtual network connection and finally one more sharing is there that is sharing of the disk partitions and disk drives of the host ad guest machines using the flash drives in which the data is stored because it is included on the USB port which is supported by windows virtual PC and all this features are accessible using the remote desktop connection.
