Q: I just got a Windows 7 laptop. I've always used Outlook and like it. Now it appears that you have to pay for it, which I never have. What should I get instead?


问：刚上手一台Windows 7笔记本电脑。我一直是用Outlook，也很喜欢。现在好像得付费使用了，而我从来没有付过费。我该换用哪一款软件呢？



A: Outlook isn't a free feature of Windows. It is a paid product, sold either alone or as part of Microsoft Office, though sometimes it's packaged into the price of a laptop. However, if you want a free email program, you might try Microsoft's Windows Live Mail, a part of a package called Windows Live Essentials. It's available at explore.live.com. Or, if you're comfortable using a free Web-based email program, you could try Hotmail, Yahoo Mail, or Gmail.


答：Outlook不是Windows的免费功能，是付费产品，有单独出售的，也有打包在Microsoft Office里面出售的，不过有时候已经含在了笔记本电脑的价格里面。但如果想要一款免费的电子邮件程序，你可以试试微软公司包含在"Windows Live Essentials"软件包里的Windows Live Mail，可在explore.live.com下载。如果愿意使用免费的、基于网页的电子邮件程序，那么你也可以试试Hotmail、Yahoo Mail或Gmail。



Q: Do you have any recommendations about how to keep data secure in the event that a Macintosh laptop is stolen or lost? We prefer to keep the data on the computer and not in the cloud.


问：万一苹果Macintosh笔记本电脑遭窃或丢失，有什么办法可以保证数据安全？我们更希望把数据放在电脑里而不是云服务器上。



A: The Macintosh has a built-in feature called FileVault, which encrypts everything in your Home folder so that only somebody who knows the password can view it. You can set up FileVault in the Security section of System Preferences. For more information, see: http://bit.ly/1DxPc0.


答：Macintosh操作系统有一个名叫"FileVault"（文件保险柜）的功能，可以给"Home"文件夹里的所有东西加密，只有知道密码的人才能看到。你可以在"系统偏好设置"(System Preferences)里面的"安全"部分设置。更多情况请点击：http://bit.ly/1DxPc0
