【 Weak current College 】 installation Windows 7 operating system before the five notes

5 may, Microsoft Official will begin allowing download Windows 7 RC. MSDN or TechNet, before the user has already been tried out. 　　We have a wide variety of system installation and upgrade RC, also refer to a lot of domestic and foreign friends and blog comments. Next, I want to organize, and share it Windows 7 installation, want to help. First, select the installation method now that you have downloaded the ISO image and burn it to DVD. 　　Next, you have two options to run the Setup program. Windows Installer properties of different depending on what you select. If your system is already installed on Windows XP, Vista, or earlier versions, you can start from the Windows operating system. 　　Alternatively, you can boot the system from the installation media. 　　Either way, you will see a dialog box appears. What is the difference? 　　if you run Setup in Windows. 　　1, you cannot run x86 version of Windows running 64-bit Installer. 　　2. install Windows 7 and Windows versions available with volume. 　　3, you must use an existing partition, cannot be changed, Setup does not recognize the unallocated space. 　　If the Windows 7 DVD boot: 1, you cannot upgrade an existing version of Windows, you can only customize the installation. 　　2, you can delete an existing partition, create a new partition, expand an existing partition, or specify an unallocated space as the location of the installation. 　　3. install Windows 7 and Windows versions available with volume. In addition, if you start Setup in Windows, you can choose the existing system running the compatibility check. 2. how to clean install if you intend to do a clean installation, it is recommended that you back up, and then from the Windows 7 DVD to start the Setup program to remove any existing partitions. Because this will save you time and reduce some trouble. 　　Now, suppose that you have backed up. 　　Since then all the data will be lost, so be sure to first store before starting. Clean install a total of four steps: 1. from the Windows DVD to start the program, follow the prompts to select a custom (Advanced) installation, and then click next to enter the picture; 　　2, click drive options (Advanced) displays all the available disk management tool; 　　3. Select a partition from the list, and then click Delete. 　　4. on the other, any additional volume for repeat the operation until the addition to the unallocated space to leave nothing out. Now, you can use the drive on all the unallocated space to complete the installation. 　　3. find the old driver should not fear in my tests, to date, windows 7 is doing very detailed. But it is not perfect, some equipment appears blank, or replaced by a generic driver. If you have already installed Windows Vista or Windows 7 in earlier versions, you do not need to use from the old system of special procedures to backup drivers. 　　Windows Vista and windows7 in a folder named FileRepository, save a local copy of all the drivers, it DriverStore subfolder. The full path is C:Windows\System32\DriverStore\FileRepository. 　　On a clean Windows 7 x 86 install, FileRepository folder contains over 900 MB of files. 　If you add a new device or update, this figure can easily exceed 1GB. When you complete a new installation of Windows 7, you can use Device Manager to install or update a driver, or simply click on your saved old driver installation. 4. fear over the old folder when you indicate that the Windows Installer to do a custom installation, it will be the old Windows, Program Files, and user folder (Documents and Settings) to move to a Windows. 　　Old folder. New installation will create an entirely new current system drive a set of top-level folders: windows, Program Files and Users. The advantage is obvious that the system of a single disk has only one partition and a large amount of free disk space, you receive a new installation without losing any data. Non-destructive new installation allows you to have a new beginning, the old data file will be safely hidden in Windows. Old folder. 　　To perform a clean-install, you can in Windows or from Windows 7 DVD boot Windows 7 Setup, click install, select custom (Advanced) option, and then, in the available disk partition list, choose the one containing your current Windows installation partition. 　　For most people, is the c drive. Click OK, you will see a warning dialog box. After completing the settings, when you first start Windows 7, you will see all your data and program files are in Windows. 　　Old folder. If you have any old data files need to be recovered, you can Users folder (Windows Vista) or found in the Documents and Settings. 5. hard disk capacity requirements to innocence in standard now, you do not need large amounts of disk space to install Windows 7. 　　Microsoft released RC minimum hardwareRecommended that the free disk space 16G. But that is not a strict requirement, the author in a 10G drive (9.9G format) on the virtual machine after installing Windows 7 Ultimate, 3.95G available disk space. Later, the author notes that a full installation of Windows 7 Ultimate x86 requires 6 to 9G space. 　　Obviously, when you install additional programs or create a data file, this amount will increase. But what should be the system partition?, according to the author's experience, 15G is a small scale, but sooner or later become nervous, so if you have enough spare disk space, it is recommended that you set aside at least 30G. Finally, I also collect about Windows 7 RC of universal knowledge, and share it: RC is Windows 7 development process in the latest beta version. Available for x 86 and x 64 format. Microsoft officially released Windows 7 before the last release. 　　Full installation of Windows 7 RC can be in one and a half hours. As for slower machines, absolutely cannot be completed within two hours. Although likely Microsoft will be adding some new desktop background or screen saver. 　　But Windows 7 RC is a fully functional version. Microsoft now isthat the last error, most content will work with the original equipment manufacturer's configuration and hardware support. 　　RC version as trial version, the public will be able to download and install. 　　Do not pay any fees. 　　Windows 7 cannot be based on the Windows XP installation, Windows 7, you must perform a net install, or is based on Vista to install on the basis of the data, as well as personalized settings migrate from XP. 　　The virtual machine has its special purpose, virtualization hardware does not support Aero graphics characteristics, therefore cannot be a true desktop experience. Most can be run on the Vista of the mainstream commercial and entertainment programs that can run on Windows 7. At the end of the Setup process prompts you to enter a product key. If you leave this box blank, the Setup will continue, your Windows 7 without any restrictions. But until you activate, you must enter a valid product key. By default, the installation of 3 days is automatically activated, you can also disable the automatic installation process. If the 30-day grace period without activation, you can continue to use the RC, but must endure trouble screen and forcing the black background. Windows 7 RC will be available in March 2010 1 stops working, this is a very long time.
