The advantages and disadvantages of "New Installation" and "Upgrade Installation" are analyzed in the two ways.
The five advantages of installing and running "dual systems"--
The three major operating systems, the current global average user usage rate of the highest three systems.
According to the market share from high to Low:
(1) Windows XP. October 2001 released. The current market share is 58%. "XP" takes the second to third letter of experience (Chinese translation: Experience) as the name of the version. The latest patch package is "Service Pack 3". According to Microsoft "Product Technology Support life cycle Policy", the final support time for System Automatic Update is April 8, 2014;
(2) Windows 7. August 2009 released. The current market share is 21%. For the name "7", Microsoft officially explained: "7" represents Microsoft (for Microcompuer and software: microcomputer software) the "Seventh Edition" of Windows system. "Service Pack 1" is in the public test. (3) Windows Vista. January 2007 released. The current market share is 13%. Vista in the translation of "vision, prospects." The latest patch package is "Service Pack 2".
There are five versions of Windows XP: Professional Edition, Home Edition, Media Center Edition, portable All-in-one platform (above all 32-bit versions) and 64-bit Edition (64-Bit Edition).
Windows 7 has six versions: flagship, Enterprise, professional, home advanced, home base, and Easy edition. The flagship and Enterprise editions are the most fully functional and best performing versions.
There are five versions of Windows Vista: Flagship, Enterprise, business, home, and home.
For preinstallation Disk File system format requirements: Windows XP with "NTFS" or "FAT32" can be recommended, "NTFS"; Windows 7, Windows Vista, must be "NTFS". On the premise of installing the common software to other disks outside the system disk, the reserved space for the system disk is recommended as follows: Windows XP is GB; Windows 7, Windows Vista is GB.
For a general installation of the above operating system, it is recommended to download the CD image and check the correct value after burning the disc, take the format of the new installation method. The biggest advantage of this way is: through the installation, to the user an authentic, clean operation platform. The price is the reinstallation of common software and drivers. By the way, here's the "Upgrade Installation" issue: This installation must be based on a lower version, which allows you to implement the most common software that was previously installed. However, the "Upgrade installation" also has its own difficult to overcome the drawbacks, mainly: The system will still retain the previous form of garbage files, of course, including the virus did not find and was removed, such as Trojans.
Install "Dual systems", which is recommended for Windows XP + windows 7. This recommendation is largely dependent on the fact that all software currently supports and is compatible with Windows XP, but that some professional software is not compatible with Windows 7, even under compatibility mode, which is currently supported by most commonly used software and compatible with Windows 7. Very few large professional software because there is a longer development cycle, follow Windows 7 also need a process. Install dual systems, you should adhere to the "from low to high version" of the installation order. If you install a second system of Windows XP on Windows 7, or if you reinstall a system after installing dual systems, you will receive an exception that only enters the second or reload system.
The title of this article "dual system" run five advantages, in short, is:
First, it is advantageous to enable the second system to continue working after a system has failed.
Second, in the two systems to install different anti-virus software, so as to increase the overall identification of viruses, trojans and kill probability.
Third, it is advantageous to analyze and judge the crux of software and hardware fault accurately through the performance of two systems.
Four, it is beneficial to use two systems through cross rotation to alleviate the visual and inertia fatigue caused by long-term operation.
Five, which facilitates the installation of fully compatible, commonly used software on both systems, and the transition from Windows XP to Windows 7 in a step-by-step process. Whether or not a "dual system" is installed depends entirely on the user's computer hardware configuration and personal preferences and job needs.
