今天哥带来一台HASEE笔记本，2G内存，i3处理器，300G的硬盘，让我装一个64位的windows7。因为只有安装64位的系统才能发挥出64位硬件的性能，否则真是浪费硬件性能资源，我这电脑都浪费两年了。
笔记本买来装着一个LINUX，查看了一下硬盘空间，用命令df -lh，十几个G，估计还有没用上的；在网上下载了一个windows7x64安装完成时候要激活，搜了几个激活码都已经不能用了，听说淘宝上有卖的，就花了5￥买了一个，成功激活！系统安装完成！
安装前：因为linux的文件系统是ext的，所以并不适用于windows。用ghost的系统盘中的分区工具，把硬盘整理成3个分区格式为NTFS，一个主分区，两个扩展逻辑分区。
把windows7 ISO文件用Ultra ISO刻录到u盘上，重u盘启动，文件提取完毕后重启windows，拔下u盘，系统就开始安装了，安装过程非常简单就略了。
哥回来看了下说，系统分区55G太小，要扩展；后面两个逻辑分区要合并成一个。
yes sir！立马开工！
google上搜索了一下扩展windows7系统分区increase windows 7 system capacity
其实windows7支持分区的压缩（压缩卷）和扩展（扩展卷），但是条件是1.要有可用的硬盘空间2.要扩展的分区和可用的硬盘空间还必须是相邻的。

Extend Windows 7 system partition扩展windows7系统分区
· Most computer users, I believe, are not likely to perform operations to system partition, because system partition stores a large number of system files and supporting files. Once these important files are lost by accident when we manage system partition,
our operating system may crash and some important data may be lost. I believe nobody is willing to see this condition. However, we have to resize system partition sometimes. Well then, is there a way to extend system partition without influencing data? Yes,
of course. In fact, Windows 7 built-in disk management tool can help us extend Windows 7 system partition without damaging data.
我相信大多数用户都不太可能会执行一些系统分区的操作，因为系统分区存储了大量的系统文件和支持文件。当我们管理系统分区的时候，一旦不小心弄丢这些文件，操作系统将会崩溃，一些重要数据也可能丢失。我相信没有人愿意看到这种情况。然而有时候我们却不得不调整系统分区的大小。这样的话，有没有一种方法可以实现扩展系统分区而又能避免影响到重要数据？当然有了！！事实上，Windows7自带的磁盘管理工具就可以帮助我们扩展系统分区并且不会毁灭数据。
Extend Windows 7 system partition with system built-in disk management tool用系统自带磁盘管理工具扩展windows7系统分区
Users who know Windows 7 built-in
disk management tool know this newly released tool introduces the function ofshrinking partition,extending
partition and other commonly used partition management functions. To know these new functions, we should follow these steps: Start-Computer-Computer Management-Disk
Management.
了解windows7自带磁盘管理工具的用户知道这个新发布的工具拥有分区压缩、扩展，和其他公共用户分区管理功能。为了解这些新功能，按以下步骤操作：开始——计算机管理——磁盘管理
The above picture is the screenshot of this disk management tool. It shows us all partition conditions. After we right click Windows 7 system partition, there will appear a shortcut menu which shows allpartition
management functions of this disk management tool.
以上是磁盘管理工具的截图。右键点击windows7系统分区，将出现一个菜单，其中展示了这个工具的所有分区管理功能。
Among these partition management functions, we can see "Extend Volume…" function button clearly. At this time, some people may ask why this function is not activated.
The reason is that there is no unallocated space adjacent to Windows 7 system partition. Although there is unallocated space on the hard disk, it still can not be used to extend Windows 7 system partition as long as it is nonadjacent to the system partition.
Therefore, the function "Extend Volume…" is not activated, and we can not extend Windows 7 system partition successfully. Actually, to solve this problem, we can seek for better solutions. For example, the third party partition magic is a
good choice. As the partition we operate is system partition which requires extremely high safety, I suggest MiniTool Partition Wizard, professional partition magic with excellent data protection.
在这些分区管理功能中，我们可以清楚的看到“扩展卷…”功能按钮，现在可能有人会问为什么这个功能是灰色不可用的呢？原因是windows7的系统分区没有相邻的未分配磁盘空间，尽管硬盘上有free space可用的空间，还是不能用来扩展到系统分区，它和系统分区不挨着嘛！所以“扩展卷……”功能不可用，我们无法扩展windows7系统分区。事实上，为了解决这个问题，我们可以寻找更好的办法。比如，第三方工具分区魔术师就是一个很好的选择。由于我们要操作的分区是系统分区所以需要极高的安全性，我建议使用MiniTool
Partition Wizard,专业分区魔术师拥有极好的数据保护能力。
Extend Windows 7 system partition with MiniTool Partition Wizard使用MiniTool Partition Wizard扩展Windows7系统分区
To use this professional partition magic, we must own it first. If we do not have, we can download it from its official websitehttp://www.partitionwizard.com/. Next, run it, and we
can see the following main interface: 左边这个网址可以下载到这个工具，运行后会看到如下界面。
The above interface shows us all partition condition. From Windows 7 built-in disk management tool, we have seen there is an unallocated space nonadjacent to the system partition, so we should move this unallocated space to the place neighboring to the system
partition. At this time, select the partition located between Windows 7 system partition and the unallocated space (here, the desired partition is Partition F:), and then click "Move/Resize" button, as the following interface
shows:
以上界面展示了所有分区的信息。前面从Windows7自带磁盘管理工具中，我们已经看到有一个和系统分区不挨着的空闲分区，所以我们要移动这个未分配空闲分区使他和系统分区挨着（毗邻）。现在，选择位于windows7系统分区和未分配空间当中的分区（这里如图，我们选中F：分区），然后点击“Move/Resize”按钮，如下图所展示。
After clicking "Move/Resize" button, we enter the following interface:点击"Move/Resize"之后，我们进入如下图的界面
In the above interface, drag the partition handle which represents partition size and partition location rightwards, and then click "OK" button. After doing this operation, Partition F: will interchange position with the unallocated space,
as the following interface shows:
在以上界面中，用鼠标按住显示分区大小的分区，向右拖动到头，然后点击OK按钮。操作完成后，分区F：将会和未分配空间互换位置，如下图所示：
In the above interface, we can see F partition and the unallocated space have been interchanged, and the unallocated space is adjacent to the system partition. Now, please select Windows 7 system partition and click "Move/Resize"
to extend Windows 7 system partition.
以上界面图上我们可以看到F：分区和未分配空间已经互换了位置，未分配空间已经和系统分区挨着（相邻）了。现在选择Windows系统分区并点击"Move/Resize"来扩展Windows7系统分区。
In the popup partition resizing interface, drag the right triangle rightwards, and then click "OK" to get the following interface:
在弹出的分区调整界面中，按住向右的三角形（注意鼠标的形状），向右拖动到头，然后点击OK按钮，会看到如下界面。
From the above main interface, we can see Windows 7 system partition has been extended, but this is just a preview. To realize real extension, we still need to click "Apply"
to perform all previous operations.
Many users who have used or are using Windows 7 may feel Windows 7 system partition becomes much smaller and is often out of space. Under this situation, if there is no unallocated space adjacent to the Windows 7 system partition, we can not accomplish system
partition extension. However, from the above demonstration, we can see MiniTool Partition Wizard, the powerful and professional partition magic, can help us create conditions for extending Windows 7 system partition and then extend Windows 7 system partition
safely and quickly. If you want to extend Windows 7 system partition, please hurry to download thispartition magic and try it.
从以上主界面中，我们看到Windows7系统分区已经扩展好了，不过这只是一个预览。要实现真正的扩展，我们还需要点击"Apply"按钮来使之前的操作生效。
许多用过或正在用Windows7的用户可能感到Windows7系统分区变的越来越小甚至要超出系统分区大小。在这种情况下，如果没有和Windows7系统分区相邻的未分配空间，我们就不能完成系统分区的扩展。然而，从上面的介绍中我们可以看到MiniTool Partition Wizard，强大专业的分区魔术师，可以帮助我们创造扩展Windows7系统分区的条件然后快速安全的扩展Windows7系统分区。如果你正需要扩展Windows7系统分区，那就赶快去下载partition
magic然后试试吧。
意外：
扩展的时候，因为软件安装在了D盘，所以在扩展C盘的时候提示，有运行的程序正在使用D盘。这时候可以①撤销之前操作②重启继续完成剩余操作，选择重启完成操作，perfect！
合并分区：
打开工具，右键点击最后一个分区E选择——delete删除，分区变成了(unallocated)未分配；然后选中第二个分区D，点击Move/Resize，右键拖动到最后，点击OK，这样D和E就合并成了一个分区；当然这只是预览，还要点击左上角的Apply按钮，使操作生效，成功！

性能问题：
由于一些软件运行反应速度巨慢，加了2G的内存，速度立刻提升！
