Windows 8昨天正式发布，现在是决定是否升级的时候了。如果您决定将Windows XP、Windows Vista或 Windows 7 机器升级到Windows 8 ，您可能希望在购买升级之前确保您的系统可以支持Windows 8 。

要检查您的 PC 是否与Windows 8兼容，您可以下载并运行Windows 8 升级助手^{(Windows 8 Upgrade Assistant)}。升级助手^{(upgrade assistant)}将继续扫描您的硬件、程序，甚至任何连接的设备，以确保它们可以与Windows 8一起使用。

Windows 8 需要某些CPU功能，如PAE、NX、SSE2等，因此如果您的计算机有点旧，最好使用此工具。

该工具还将为您提供程序的兼容性报告^{(compatibility report)}，并让您知道在升级之前是否需要卸载程序或更新程序。下载、安装并运行后，该程序将自动开始扫描您的计算机以查找应用程序和设备^{(apps and devices)}。

然后它会告诉您哪些应用程序兼容以及您需要查看哪些应用程序。

Windows 8中有一些新功能，例如安全启动^{(secure boot)}、快照和快速启动。如果您的系统不支持任何这些项目，升级助手将通知您：^{(Upgrade assistant)}

如果您还不知道，Windows 8 不包含用于播放DVD^(DVDs)的内置软件。如果您想要该功能，则必须购买Pro 包^{(Pro pack)}并获得Windows Media Center。请注意，如果您已经拥有 Windows 8 Pro，您可以在2013 年1 月 31^{(January 31st)}日之前免费获得 Windows Media Center Pack^{(Windows Media Center Pack for free)}，所以快来获取吧！

此外，Microsoft Security Essentials在Windows 8中被Windows Defender取代。基本上是一样的，但无论出于何种原因，它们都将Windows Defender包含在Windows 8中。因此，如果您在Windows 7上安装了Security Essentials，则必须在升级之前将其删除。

您还可以获得适用于Windows 8的兼容^{(Windows 8)}软件和硬件^{(software and hardware)}列表：

单击下一步时，系统会询问您要保留的内容。这将确定最适合您的Windows 8版本。^{(Windows 8)}

请注意，根据您拥有的Windows版本，您只能升级到Windows 8的某些版本。例如，如果您有Windows 7 Ultimate，则只能升级到Windows 8 Pro。

如果您有 Windows 7 Pro，则可以升级到Windows 8 Pro 或 Enterprise^{(Pro or Enterprise)}。如果您有 Windows 7企业版^(Enterprise)，则只能升级到Windows 8 企业版^(Enterprise)。查看Wikipedia文章了解更多详细信息。

就我而言，因为我有 Windows 7 Ultimate，所以我选择的任何选项都给了我相同的结果：Windows 8 Pro售价 39.99 美元。

这就是Windows 8 升级助手^{(Upgrade Assistant)}的全部内容。它主要用于确定哪些硬件和软件^{(hardware and software)}无法在Windows 8上运行。如果您有一台较旧的 PC 并且您不确定您的CPU是否会受到Windows 8的支持，这也很有用。享受！

Is Your PC Ready for Windows 8?

Windows 8 was officiallу released yesterday and it’s now time to deсide whether you want to upgrade or not. If you have decided to upgrade а Windows XP, Windowѕ Vista or Windоws 7 machine to Windows 8, you probably want to make sure your sуstem can support Windows 8 before you buy the upgrade.

To check if your PC is compatible with Windows 8, you can download and run the Windows 8 Upgrade Assistant. The upgrade assistant will go ahead and scan your hardware, programs, and even any connected devices to make sure they will work with Windows 8.

Windows 8 requires certain CPU features like PAE, NX, SSE2, etc, so it’s a good idea to use this tool if your computer is a bit on the older side.

The tool will also give you a compatibility report for your programs and let you know whether you need to uninstall the program or update the program before upgrading. Once you download it, install it and run it, the program will automatically start scanning your computer for apps and devices.

It will then tell you which apps are compatible and which apps you need to review.

There are some new features in Windows 8 like secure boot, snap, and fast startup. Upgrade assistant will notify you if any of those items are not supported by your system:

If you didn’t already know, Windows 8 does not include built-in software to play DVDs. If you want that feature, you’ll have to buy the Pro pack and get Windows Media Center. Note that if you already have Windows 8 Pro, you can get Windows Media Center Pack for free until January 31st, 2013, so get it fast!

Also, Microsoft Security Essentials is being replaced by Windows Defender in Windows 8. It’s basically the same thing, but for whatever reason they are including Windows Defender built into Windows 8. So if you have Security Essentials installed on Windows 7, you’ll have to remove it before upgrading.

You also get a list of compatible software and hardware that will work with Windows 8:

When you click Next, you’ll be asked what you would like to keep. This will determine which version of Windows 8 will work best for you.

Note that depending on what version of Windows you have, you can only upgrade to certain editions of Windows 8. For example, if you have Windows 7 Ultimate, you can only upgrade to Windows 8 Pro.

If you have Windows 7 Pro, you can upgrade to Windows 8 Pro or Enterprise. If you have Windows 7 Enterprise, you can only upgrade to Windows 8 Enterprise. Check out the Wikipedia article for more details.

In my case, since I have Windows 7 Ultimate, any option I selected gave me the same result: Windows 8 Pro for $39.99.

That’s about all there is to the Windows 8 Upgrade Assistant. It’s mostly useful for figuring out which hardware and software will not work on Windows 8. It’s also useful if you have an older PC and you’re not sure if your CPU is going to be supported by Windows 8. Enjoy!
