你必須要知道的安裝Windows 10的知識

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系統 於7月29日發佈。正版的Win 7，Win8以及Win8.1用戶第一年能夠享受系統免費升級。你可以根據本篇文章判斷自己的電腦是否也能享受免費系統升級。

Can your PC run it?

你的個人電腦是否可以運行Win 10 系統？

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.

答案對大多數人來說都是肯定的。Win 10系統對硬件的最低要求與Win7系統一樣。此外，還可以從自己的桌面判斷自己的電腦是否可以運行Win10系統。你需要一臺運行Win 7 服務包或者Win8.1更新包的電腦或者平板電腦。單擊桌面右下角任務欄的Windows 圖標，從右邊選項欄中，選擇“我的電腦”選項。

Free up space

空間清理

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.

安裝Win10系統至少需要16G的空間。從“我的電腦”，選擇C盤，右鍵單擊選擇“屬性”。還可以單擊“磁盤清理”按鈕釋放更多空間。但該方式清理的空間往往不夠，因此你可以卸載不常使用的程序，以獲取足夠的空間。

Back up your data to the cloud or an external drive

在計算機雲或者外部驅動中備份數據

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.

不管你是不是在升級Win10系統，將數據備份都是很好的選擇。你可以利用雲服務或者外部驅動對數據進行備份。只要將一些你想保存好的個人文件夾拖拽只雲服務或者外部驅動即可。Win8系統可以利用文件歷史記錄自動備份個人文件。

Create a system image

創建系統圖標

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系統和Win8系統都有創建系統圖標的工具。在“控制面板”“系統和安全”一欄中選擇“備份”。在左邊選擇創建系統圖標，選擇保存位置，並按“下一步”按鈕。最後時，你還可以選擇創建系統恢復盤。如果遇到問題，系統恢復盤能夠幫您解決問題。此外還可以創建USB恢復硬盤。

Update device drivers

升級設備驅動程序

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.

安裝新版本的Windows 系統時，都要覈實電腦的驅動器是否兼容。這有助於避免電腦硬件可能引起的問題。很多硬件製造商已經開發了Win 10系統的驅動器。在電腦製造商支持網頁上即可檢查驅動器。此外，我們還建議，將下載的驅動器存儲在外部拇指驅動器中，因爲安裝過程中，很可能用到該驅動器。
