你必须要知道的安装Windows 10的知识

Windows 10 is set to arrive on July 29. The update will be free for the first year for qualifying Windows 7, Windows 8 and Windows 8.1 users. You can find out if you qualify for the free upgrade here.

Win10系统 于7月29日发布。正版的Win 7，Win8以及Win8.1用户第一年能够享受系统免费升级。你可以根据本篇文章判断自己的电脑是否也能享受免费系统升级。

Can your PC run it?

你的个人电脑是否可以运行Win 10 系统？

The answer is most likely yes. Windows 10 requires the same minimum hardware requirements as Windows 7. You can also check to see if your machine is capable of running Windows 10 right from your desktop. You will need a computer or tablet running Windows 7 Service Pack 1 or Windows 8.1 Update. From the desktop, click on the small Windows icon located at the right end of the taskbar, and select the "Check my PC" option from the left menu.

答案对大多数人来说都是肯定的。Win 10系统对硬件的最低要求与Win7系统一样。此外，还可以从自己的桌面判断自己的电脑是否可以运行Win10系统。你需要一台运行Win 7 服务包或者Win8.1更新包的电脑或者平板电脑。单击桌面右下角任务栏的Windows 图标，从右边选项栏中，选择“我的电脑”选项。

Free up space

空间清理

You will need at least 16GB of free space to install Windows 10. To check how much free space is on your hard drive, head to Computer, right-click the C:/ drive, and select Properties. You can free up some space by clicking the Disk Cleanup button. This usually won't free up enough space, so you may also have to uninstall programs that you no longer use.

安装Win10系统至少需要16G的空间。从“我的电脑”，选择C盘，右键单击选择“属性”。还可以单击“磁盘清理”按钮释放更多空间。但该方式清理的空间往往不够，因此你可以卸载不常使用的程序，以获取足够的空间。

Back up your data to the cloud or an external drive

在计算机云或者外部驱动中备份数据

Regardless if you are upgrading to Windows 10 or not, it's always a good idea to back up your data. You can use a cloud service or an external hard drive. Simply drag and drop the personal files you would like to keep safe to the cloud or external drive. Windows 8 users can also use the File History feature to automatically back up personal files.

不管你是不是在升级Win10系统，将数据备份都是很好的选择。你可以利用云服务或者外部驱动对数据进行备份。只要将一些你想保存好的个人文件夹拖拽只云服务或者外部驱动即可。Win8系统可以利用文件历史记录自动备份个人文件。

Create a system image

创建系统图标

Both Windows 7 and Windows 8.1 come with a tool that lets you create a system image. Head to the Control Panel and select "Back up your computer" under the Systems and Security section. On the left choose to create a system image, pick the location you want to save it to, click Next. At the end of the process, you will have the option to create a system repair disc. This can be used to help you repair Windows if you run into any problems. You can also create a USB recovery drive.

Win 7系统和Win8系统都有创建系统图标的工具。在“控制面板”“系统和安全”一栏中选择“备份”。在左边选择创建系统图标，选择保存位置，并按“下一步”按钮。最后时，你还可以选择创建系统恢复盘。如果遇到问题，系统恢复盘能够帮您解决问题。此外还可以创建USB恢复硬盘。

Update device drivers

升级设备驱动程序

Whenever installing a new version of Windows, it's always a good idea to verify that you're using compatible drivers. This will help you avoid stability issues that could arise due to your computer's hardware manufacturers already have Windows 10 drivers available now. To check for drivers, head to your PC manufacturer's support website. I also recommend downloading the drivers to an external thumbdrive, just in case you need them during the installation process.

安装新版本的Windows 系统时，都要核实电脑的驱动器是否兼容。这有助于避免电脑硬件可能引起的问题。很多硬件制造商已经开发了Win 10系统的驱动器。在电脑制造商支持网页上即可检查驱动器。此外，我们还建议，将下载的驱动器存储在外部拇指驱动器中，因为安装过程中，很可能用到该驱动器。
