如果您正在运行Windows XP或Windows Vista并且正在考虑切换到Windows 7，您可能想知道所有不同版本之间的区别是什么。与OS X不同，它为每个人提供一个版本，Windows试图将其分解为具有不同价格点的几个组。根据您使用计算机的目的，您可能只需要Home版本，或者您可能需要Ultimate。
实际上有 6 个不同版本的Windows 7，但我们只担心 3 个，因为其余的并不真正可供消费者购买。有Windows 7 Starter，通常在上网本上。Windows 7 Home Basic在新兴市场可用，但在美国不可用。Windows 7 Enterprise 通过批量许可销售给公司和机构。
在这篇文章中，我将讨论Windows 7 Home Premium、Professional和Ultimate之间的区别。请注意，如果您购买的是最基本的Windows版本，您仍然可以随时使用Windows Anytime Upgrade进行升级。基本上(Basically)，家庭(Home)版包括专业版(Professional)和旗舰版(Ultimate)，但这些额外功能只有在您购买时才会安装。您可以从Windows本身运行随时升级。
要快速了解差异，您可以随时访问Microsoft的以下页面：
我发现他们的比较有点过于简单而且不是很明确，特别是如果你想知道每个版本的所有额外功能。这张图表只是简单地介绍了一些非常基本的点，其中大部分都是无用的，例如“改进的桌面导航”和“ Internet Explorer 8 ”。
我将尝试更完整地列出每个版本缺少或添加的功能。让我们首先从家庭高级版(Home Premium)开始，因为它构成了所有其他版本的基础。
家庭高级版
以下是关于Home Premium 的各个方面：
- 对于初学者，Windows 7 Home Premium仅在2015 年1 月(January 2015)之前受支持。相比之下，在2020 年 1 月之前(January 2020)支持Windows 7专业版(Professional)。奇怪的是，Windows 7 Ultimate也只支持到2015 年1 月(January 2015)。
- (Max)家庭高级版的(Home Premium)最大内存为16 GB。对于Professional和Ultimate，它是 192 GB（64 位Windows）
- Home Premium 最多只能支持 1 个CPU。Professional及更高版本最多可支持 2个 CPU(CPUs)。
- Home Premium 无法备份到网络位置（仅限本地备份）。Professional和Ultimate可以备份到网络。
- 家庭高级版只能是远程桌面(Remote Desktop)的客户端（只能从另一台机器连接）。使用Professional和Ultimate，您可以将Windows用作远程桌面的主机并连接到其他计算机。
- 家庭高级版(Home Premium)和最重要的是支持家庭组(HomeGroups)
专业的
除上述几点外，Professional还具有以下功能和服务：
- 支持动态磁盘(Dynamic Disks)。这允许软件实现RAID，这对于具有多个硬盘驱动器的系统可能很有用。
- 加密文件系统——允许(File System – Allows)文件系统级加密。不如BitLocker安全，后者仅在Ultimate中可用。
- 位置感知打印
- 演示模式 - 让(Mode – Lets)您在演示时更改Windows的行为，即控制音量、显示不同的壁纸、防止屏幕保护程序出现等。
- 组策略 – 允许您在本地或通过(Group Policy – Allows)Windows Server 2003/2008Windows操作系统的几乎所有方面
- 脱机文件(Offline Files)和文件夹重定向 – 同样(Folder Redirection – Again)，更多的是加入域的Windows机器的功能(Windows)
- 能够加入Windows域- 家庭高级版(– Home Premium)无法加入Windows域
- Windows XP 模式 – 允许(Windows XP Mode – Allows)您在Windows 7中运行Windows XP SP3。用于与旧程序兼容。
- 软件限制政策
最终的
Ultimate中只有少数对消费者有用的额外功能。Ultimate中的大多数附加功能都适用于IT 专业人员(IT Professionals)。
- BitLocker 驱动器加密 –(BitLocker Drive Encryption –)与使用文件系统级加密的EFS不同，BitLocker使用全盘加密。
- 能够立即在 35 种不同的语言之间切换
- AppLocker – 能够(AppLocker – Ability)阻止软件在计算机上运行
- BranchCache – 允许(BranchCache – Allows)通过WAN快速访问文件(WAN)
- 从VHD(VHD – Ability)直接启动–计算机可以在有或没有主机操作系统的情况下从VHD文件启动(VHD)
- DirectAccess – 让(DirectAccess – Keeps)移动用户在旅途中保持连接
- 虚拟桌面基础架构(Desktop Infrastructure)( VDI ) 增强功能
因此，即使Ultimate听起来很棒，但对普通消费者来说确实没有用。即使在一定程度上，Professional对普通用户也不是超级有用。如果需要，最好先获得家庭高级版(Home Premium)，然后升级到专业版(Professional)或旗舰版(Ultimate)。希望(Hopefully)Windows 8 没有更多版本可供选择！
Difference between Windows 7 Home, Professional and Ultimate
If you are running Windows XP оr Windows Vista and are thinking about making the switch to Windows 7, you might be wondering what’s the diffеrence between all the different versions. Unlike OS X, which has one vеrsion for everyone, Windows tries to break it down into several groups with different рriсe poіnts. Depending on what you will be using your computer for, you may only need thе Home version or you may need Ultimate.
There are actually 6 different versions of Windows 7, but we’ll only worry about 3 because the rest are not really available for consumers to buy. There is Windows 7 Starter, which is usually on netbooks. Windows 7 Home Basic is available in emerging markets and not here in the US. And Windows 7 Enterprise is sold through volume licensing to companies and institutions.
In this post, I’ll talk about the differences between Windows 7 Home Premium, Professional and Ultimate. Note that if you buy the most basic version of Windows, you can still upgrade at any time using Windows Anytime Upgrade. Basically, the Home version includes Professional and Ultimate, but those extra features will only be installed when you purchase it. You can run Anytime Upgrade from within Windows itself.
To get a quick overview of the differences, you can always go to the following page from Microsoft:
I find their comparison a bit too simplified and not very clear cut, especially if you want to know all the extra features of each version. This chart just goes over some very basic points, most of which are useless like “improved desktop navigation” and “Internet Explorer 8”.
I’ll try to give a more complete listing of what features are missing or added to each version. Let’s start off with Home Premium first since that forms the base of all other versions.
Home Premium
Here are the various points about Home Premium:
- For starters, Windows 7 Home Premium is only supported until January 2015. By contrast, Windows 7 Professional is supported until January 2020. Oddly, Windows 7 Ultimate is only supported until January 2015 also.
- Max memory for Home Premium is 16 GB. For Professional and Ultimate it’s 192 GB (64-bit Windows)
- Home Premium can only support up to 1 CPU. Professional and higher can support a max of 2 CPUs.
- Home Premium cannot backup to a network location (only local backups). Professional and Ultimate can backup to the network.
- Home Premium can only be a client for Remote Desktop (can only be connected to from another machine). With Professional and Ultimate you can use Windows as a host for remote desktop and connect to other machines.
- Home Premium and above all support HomeGroups
Professional
In addition to the points mentioned above, Professional also has the following features and services:
- Support for Dynamic Disks. This allows software implementation of RAID, which could be useful for a system with multiple hard drives.
- Encrypting File System – Allows for filesystem-level encryption. Not as secure as BitLocker, which is only available in Ultimate.
- Location Aware Printing
- Presentation Mode – Lets you change the behavior of Windows while giving presentations, i.e. control volume, display different wallpaper, prevent screensaver from appearing, etc.
- Group Policy – Allows you to control just about all aspects of the Windows operating system locally or via Windows Server 2003/2008
- Offline Files and Folder Redirection – Again, more a feature of a Windows machine joined to a domain
- Ability to join a Windows domain – Home Premium cannot join Windows domains
- Windows XP Mode – Allows you to run Windows XP SP3 inside Windows 7. Used for compatibility with older programs.
- Software Restriction Policies
Ultimate
There are only a few extra features in Ultimate that are useful for consumers. Most of the additional features in Ultimate are for IT Professionals.
- BitLocker Drive Encryption – As opposed to EFS, which uses file system level encryption, BitLocker uses full disk encryption.
- Ability to switch between 35 different languages instantly
- AppLocker – Ability to block software from running on the computer
- BranchCache – Allows for fast file access across a WAN
- Direct boot from VHD – Ability for a computer to boot from a VHD file with or without a host operating system
- DirectAccess – Keeps mobile users connected while on the go
- Virtual Desktop Infrastructure (VDI) enhancements
So even though Ultimate sounds great, it’s really not useful for the average consumer. Even to a degree, Professional also is not super useful for the average user. It’s probably best to get Home Premium and then upgrade to Professional or Ultimate if you ever need to. Hopefully, Windows 8 does not have even more versions to choose from!
