Windows 7 Although a lot of improvements, but still inevitable problems, let's talk about the solution to the common problems of Windows 7. First, unable to boot Unable to boot is a more common and more serious fault. Previously under XP, this kind of fault requires manual repair by the user. Under Windows 7, you only need to boot the machine through the CD to enter the Recovery Console, and then enter the fixboot command, Windows 7 will automatically detect the startup failure, and automatically use the BCDMD command to repair. This is a great help for the average user and is commendable. Second, the sidebar weather can not be displayed In the Chinese version of Windows Windows 7, the "Weather" sidebar tool is not available by default. The reason is because the locale is not correct, you can fix it by following the steps below. 1. Open “Control Panel & Rarr; Clock, Language and Region & Rarr; Regional and Language Options" 2. Set the "current format" to “English(US)” 3. Go to “Location” Page, set "current location" to “USA" 4. Go to “Manage", click “Change system locale", set to “English (United States)” Start your computer. 6. Click the Settings button in the upper right corner of the Weather Widget and use the Pinyin to enter the name of the city you are looking for in the “Current Location” text box. For example, Beijing can enter “Beijing” to view the weather of the corresponding city. It is. However, after setting the zone to the US, some software may not display Chinese properly, but I heard that Microsoft has fixed this problem in Windows Update. Third, the screenshot flower screen Many times you will find that Windows 7 itself shows no problem, but whether it is using the Print Screen button, or other screenshot tools, the resulting map will have a part of the screen, sometimes a piece, sometimes a piece. This is mainly caused by the imperfect graphics card driver that comes with Windows 7. The solution is to download and install the latest version of the graphics card driver, which can be easily solved. Fourth, the drive letter is disordered The drive letter disorder often occurs from the Win95 era, this time Windows 7 is more serious. If you are installing Windows 7 from a CD, the system will set its partition to Area C, and then arrange other partitions according to management. To solve the Windows 7 drive letter is not easy, you need to manually develop the drive letter in the disk management, and then re-upgrade the installation system. The specific steps are as follows: 1. Go to “ Control Panel & Rarr; Management Tools & Rarr; Computer Management & Rarr; Disk Management & rdquo;, then set the wrong drive letters one by one. 2, restart Windows 7, you will receive a lot of error prompts, and can not enter the desktop. Press “Win+R” to activate the “Run” box, then click “Browse” to find Setup.exe under your Windows 7 installation CD, click “OK” to start the Windows 7 installer. 3, when the installation program wants you to choose to upgrade or a new installation, you must choose a new installation, so after installation, Windows 7 will not tamper with your drive letter. The old Windows 7 will be automatically backed up to a Windows.old directory by the installer, although it can be deleted. Fifth, the use of QQ blue screen Before the 2007 version of QQ can not be used normally under Windows 7, a blue screen will be running, this is because the keyboard input encryption control used the underlying driver technology, and is not compatible with Windows Windows 7. Solution: First close QQ, then enter the QQ installation directory, and delete npkcrypt.sys, npkcrypt.vxd and npkcusb.sys three files, you can start QQ. However, since the relevant files of the keyboard encryption control have been deleted, QQ will prompt your machine to have a Trojan virus. Don't worry about it, just use the soft keyboard to enter the password to log in. 6. Retrieve the disappeared "Run” dialog box By default, the bottom of the Windows 7 Start menu is not the familiar "Run" command, which will cause inconvenience to some higher-level operations. . We can use the following two methods to bring up the "Run" dialog box. 1, through the "Win + R & rdquo; key combination, you can open the "Run" dialog box, this trick we have used in the fourth question. 2. Right click on the start menu, select “Attributes”, enter the start menu property setting interface, click the “Customize” button at the bottom, and find “Show Run” in the list box below. Select, then click “ Confirm & rdquo; Exit, you will find that the "Run" & rdquo; command reappears at the bottom of the Start menu.
