I have always been regarded as a computer master by female students. In fact, the necessary killing technique is to reinstall the system. This handfulness has made me have a high prestige among the sisters, but the saying goes, giving people a fish. It's better to teach people to fish. Below is a brief introduction to the process of a super-simple system, so that the sister can become a computer master like me. First, choose the system in mind. Here I recommend everyone to use the genuine Win7 system, first of all Win7 system is relatively mature, strong compatibility, rich features, more convenient operation. Secondly, genuine Win7 can provide users with more stable and better performance. More importantly, the genuine system is safer to use and less vulnerable to network attacks. There are many ways to purchase genuine Win7. If you have already purchased the Win7 system in your computer and want to enjoy more functions, you may wish to purchase the upgrade key directly, which will save a lot of money. Another thing to note is that there are many versions under Win7. It is very important to choose a suitable version. It is recommended that you use the Home Premium Edition or the Ultimate Edition, which is more feature-rich. At the same time, Microsoft will launch the Win7 version of the preferential upgrade service from time to time. From February to March 31 this year, a new round of special offers has been launched. Users who pre-install the Win7 regular version can upgrade to the premium version at a preferential price. Beijing, Shanghai and other places such as Hongtu Sanbao, Meicheng, Wande City and other designated stores, users can also purchase through the network, such as Jingdong, New Egg, Yixun and other online stores. Second, choose what way to install the system to install Win7 There are many ways, according to different purchase channels, roughly divided into upgrade key, CD image installation, U disk, hard disk image installation, upgrade installation means that the computer has installed genuine win7 The system can upgrade the system directly through the upgrade key purchased at a more favorable price, such as upgrading from Home Basic to Home Premium, or upgrading to Professional and Ultimate; if you purchase a boxed disc, An optical drive is required to install the system. A product key is provided in the box. The product key can be used multiple times, but only for one computer. With many ultrabooks and portable computers, the optical drive is gradually losing. Once used, so when there is no optical drive, we can use U disk, mobile hard disk, etc., or install the system. As far as the difficulty of system installation is concerned, it is almost the same, but the boot media is different. For example, using U disk boot, we need to make some settings in bios, and the computer with CD-ROM can directly boot with CD. This article mainly introduces the way to use CD-ROM installation. This method is more safe, convenient and easy to operate, and is more suitable for the use of computer white girls. 1. Compatibility check Because I recommend that you choose Win7 system, for XP users, the compatibility check before installing the system is necessary. By clicking the online check compatibility under the installation interface, the installation wizard will automatically enter Microsoft. The website, through the download "Win7 upgrade consultant", the hardware is tested, it will tell you in detail whether there is a problem with the installation of Win7. 2. Official installation into the installation interface Select “ now install & rdquo; enter the installation wizard in the installation of the important update interface, you can see two options, here for the smooth installation, it is recommended that you choose the recommended option above "ld" To get the latest installation update & rdquo; enter the "Articles" interface, tick the acceptance, and then proceed to the next step. Then enter the "Select Installation Type" interface, the installation wizard introduces two ways, the upgrade above Mode, that is, upgrade from the existing system to the latest Win7 system, but the way to reserve a large number of junk files in the previous system, it is not recommended, it is recommended that you back up the useful resources in the system partition before installation, in Select the custom mode here and proceed to the next step. After entering "custom mode", we can re-format the hard disk in the computer and partition the hard disk, etc., because Win7 has a large amount of system resources, so at least 30G to 40G space should be reserved under the system partition. Ensure the stable operation of the computer. After selecting the installed partition, the computer will automatically install the system. The computer will restart several times during the whole process. Everyone waits for the progress bar to complete. 3. After the installation is completed, the progress bar is read, enter the Win7 settings window, we set the user name, password, type the key, enter the time, etc., then enter the new system interface, the beautiful new Windows Logo will be presented In front of you. Third, other installation methods precautions Here I just introduced the simplest of all the installation system methods. When using U disk and hard disk image installation, in addition to downloading the image, the user also needs to set the priority setting of the computer, and perform system booting on the U disk and the hard disk, and then perform the above installation process. In addition, Win7 system is divided into 32-bit and 64-bit. For a computer with 2GB memory capacity, it is more suitable to install a 32-bit system. Through the above simple operation, you can make your love machine regain its vitality. Even the sisters who don't know the computer, I believe that they can become a computer master.
