Windows 10有多大？大小因您安装的Windows 10的确切版本而异。(Windows 10)这还取决于您是从旧版本的 Windows(older version of Windows)升级还是进行了全新安装。
微软官方对Windows 10的最低要求为64 位版本的操作系统指定了 20GB 的可用空间。在实践中，安装最终可能比这大得多。以下是一些实用的方法，您可以通过这些方法将Windows 10置于速成节食状态。
杀死 Windows 膨胀软件
Windows 10 不再是微软(Microsoft)真正关心直接销售的产品。虽然他们很乐意拿你的钱购买Windows 10 许可证(Windows 10 licence)，但真正的现金来自广告、云服务和通过Windows 应用商店(Windows Store)向你销售应用程序。
您新安装的Windows 10包含一些您可能没有想到的应用程序。包括Candy Crush(Candy Crush)和其他免费的垃圾游戏(Games)等游戏，这些游戏占用了宝贵的空间。您可以从通常的“添加或删除程序”菜单中轻松摆脱这些。
对于更顽固的英国媒体报道软件，您将需要一些第三方帮助。例如，BloatBox是一个简洁的开源(Open Source)应用程序，可以让您从Windows中删除顽固的垃圾软件。
转储您不使用的默认应用程序
Windows 附带了相当长的默认应用程序列表，例如 Web 浏览器，许多人从未使用过。虽然它们实际上并没有占用那么多空间，但您应该知道删除它们的选项。
虽然您可以删除一长串Windows 10默认应用程序，但为什么不从这(Windows 10)9 个不需要的 Windows 10 应用程序和程序(9 Unwanted Windows 10 Apps and Programs)开始。您可以使用这些相同的说明来删除其他类似的应用程序。
更改默认文件夹位置
Windows设置了许多用于存放常用文件的标准位置。有一个文件夹用于存放您的文档、下载内容、视频，当然还有用于Windows 桌面(Windows Desktop)的存储空间。默认情况下，这些文件夹与Windows(Windows)位于同一硬盘上。但是，情况并非如此。
此技巧仅适用于您拥有多个硬盘驱动器的情况。但是，大多数现代计算机现在都有一个用于Windows(Windows)和应用程序的快速（但很小）固态驱动器。然后，他们有一个缓慢（但很大）的机械驱动器，用于存储不需要高性能存储的媒体和其他文件。
通过更改默认Windows 10文件夹的文件夹位置，您可以将这些文件移出主驱动器。虽然这实际上并没有使Windows 10变得更小，但它确实有助于将其占用空间分散到多个驱动器上。虽然更改默认文件夹位置的过程是相同的，但如何在 Windows 10 中更改默认下载位置(How To Change Default Download Location In Windows 10)将使您从最大的空间占用开始。
将(Move)其他应用程序从(Apps Off)系统驱动器中移出(System Drive)
如果您有多个硬盘驱动器，则不必从与Windows相同的驱动器运行应用程序！您可以通过移动应用程序来释放系统驱动器空间，而不是尝试缩小Windows 。
Windows使这很容易。只需从(Just)开始菜单(Start Menu)中打开添加或删除 Windows(Add or Remove Windows)应用程序并将驱动器设置为您的系统驱动器。这只会显示该驱动器上的软件。单击(Click)任何条目以查看该应用程序是否支持移动到另一个驱动器。如果您看到“移动”按钮，您可以将该应用程序无缝移动到另一个驱动器。
禁用休眠
休眠是操作系统的一项特殊功能，其中RAM的全部内容都存储在磁盘中。休眠的计算机可以完全关闭并拔下电源。当您再次打开它时，休眠文件被复制回RAM，并且计算机可以从上次中断的地方继续。
虽然休眠仍然有用，但它主要适用于没有电池的台式计算机。在笔记本电脑上，睡眠模式是最有意义的，因为即使断电，板载电池也会维持运转。即使是大多数桌面用户也从未真正使用过休眠功能，因为在现代机器上冷启动是如此之快。然而，您的机器上仍可能会激活休眠状态，从而占用千兆字节的宝贵空间。
好消息是您可以禁用休眠并删除休眠文件。只需按照我们的什么是 Hiberfil.sys 以及如何在 Windows 10 中删除它(What is Hiberfil.sys and How to Delete It in Windows 10)指南。
在Windows 10中使用CompactOS 选项(CompactOS Option)
在Windows 10中，有一个鲜为人知的功能，称为CompactOS。此功能将Windows 操作系统(Windows OS)文件保存在压缩文件映像中。Windows没有像往常一样将其解压到硬盘分区，而是动态解压缩它需要的文件。
这允许 Windows 在比平时小得多的驱动器上运行，这在某些系统上是必需的，例如具有非常小的SSD(SSDs)的超极本。我们会说它在具有 64GB 或更少主存储空间的系统上最有意义。
Windows通常会在合适的系统上自动且静默地激活CompactOS 。但是，您可以手动激活它，但会降低性能。由于CPU现在必须解压缩数据以及执行其常规工作。
为了修改CompactOS周围的任何内容，您必须使用命令提示符(Command Prompt)或PowerShell。我们更喜欢PowerShell！
- 只需右键单击开始按钮(start button)并选择Windows PowerShell (Admin)即可打开该程序。
2. 要检查您的计算机是否已经在运行CompactOS ，请键入以下内容并按 Enter：
Compact.exe /CompactOS:query
3. 如果您收到CompactOS已经处于活动状态的消息，则无需执行任何其他操作。如果不是，您可以通过键入以下内容然后按 Enter 来激活它：
Compact.exe /CompactOS:always
完成压缩作业可能需要几分钟时间，具体取决于您的系统规格。
要再次禁用CompactOS，请使用以下命令：
Compact.exe /CompactOS:never
缩小您的虚拟内存分配
当您的计算机用完物理RAM时，它必须开始使用称为分页文件的东西将数据交换到您的硬盘驱动器。该页面文件占用了硬盘驱动器上的保留空间。
您确实有一些选择。例如，您可以完全禁用页面文件。我们通常不建议这样做，但在某些具有大量RAM的系统上，这可能不是问题。
您可以简单地缩小由Windows确定的页面文件大小。一般的经验法则是您的分页文件应该是物理RAM的 1.5 倍，但您可以随意更改该规则。
最后，您可以将分页文件移动到与安装 Windows 的硬盘不同的内部硬盘上。这(Which)将释放系统驱动器上的空间。有关如何微调页面文件大小的所有详细信息，请查看如何优化 Windows 中的页面文件(How To Optimize The Paging File In Windows)。
小就是美
Windows 10（实际上是大多数版本的Windows）以特别臃肿而著称。然而，如果你把东西夹在所有正确的地方，那么它可能是一个令人惊讶的苗条操作系统。只要(Just)记住不要太热心。你可能会错误地取出一些重要的东西！
How Big Is Windows 10 and Can It Be Reduced?
How big is Windows 10? The size varies baѕed on the exact version of Windowѕ 10 you have inѕtаlled. It also depends on whether yоu upgraded from an older version of Windows or have made a fresh install.
Microsoft’s official minimum requirements for Windows 10 specifies 20GB of free space for the 64-bit version of the operating system. In practice, installations can end up much larger than that. Here are some practical ways in which you can put Windows 10 on a crash diet.
Kill Off Windows Bloatware
Windows 10 isn’t really a product that Microsoft cares about selling directly anymore. While they’re happy to take your money for a Windows 10 licence, the real cash comes from advertising, cloud services and selling you apps through the Windows Store.
Your new installation of Windows 10 includes a few apps that you might not expect. Games such as Candy Crush and other free-to-play, trashy titles are included and take up precious space. You can get rid of these pretty easily from the usual “Add or Remove Programs” menu.
For more stubborn forms of bloatware, you’re going to need a little third-party help. For example, BloatBox is a neat little Open Source application that will let you remove stubborn crud software from Windows.
Dump Default Apps You Don’t Use
Windows comes with a fairly long list of default apps, such as web browsers, that many people never use. While they don’t actually take up that much space, you should be aware of the option to remove them.
While there’s a long list of Windows 10 default apps you could remove, why not start with these 9 Unwanted Windows 10 Apps and Programs. You can use those same instructions to remove other similar applications.
Change Default Folder Locations
Windows sets up a number of standard places where common files go. There’s a folder for your documents, downloads, videos and of course the storage space for the Windows Desktop. By default, these folders reside on the same hard drive as Windows. However, that doesn’t have to be the case.
This trick only works if you have more than one hard drive. However, most modern computers now have a fast (yet small) solid state drive for Windows and applications. They then have a slow (yet large) mechanical drive for media and other files that don’t need high-performance storage.
By changing the folder locations for default Windows 10 folder, you move those files off your primary drive. While this doesn’t actually make Windows 10 any smaller, it does help spread its footprint across multiple drives. While the process for changing default folder locations is the same, How To Change Default Download Location In Windows 10 will get you started with the largest space hog.
Move Other Apps Off Your System Drive
If you have more than one hard drive, you don’t have to run applications from the same drive as Windows! Instead of trying to shrink Windows, you can free up system drive space by moving applications.
Windows makes this easy. Just open the Add or Remove Windows app from the Start Menu and set the drive to your system drive. This will only show software on that drive. Click on any of the entries to see if that application supports moving to another drive. If you see the “Move” button you can seamlessly move that application to another drive.
Disable Hibernation
Hibernation is a special feature of an operating system where the entire contents of RAM are stored to disk. A hibernating computer can be switched off completely and unplugged. When you power it on again the hibernation file is copied back to RAM and the computer can continue right where it left off.
While hibernation is still useful, it’s mainly for desktop computers which don’t have batteries. On a laptop sleep mode makes the most sense, since even if the power goes out the onboard battery will sustain things. Even most desktop users never really use the hibernation function, since cold booting is so fast on modern machines. Yet hibernation might still be activated on your machine, taking up gigabytes of valuable space.
The good news is that you can disable hibernation and delete the hibernation file. Just follow our What is Hiberfil.sys and How to Delete It in Windows 10 guide.
Use the CompactOS Option in Windows 10
In Windows 10, there’s a little-known feature known as CompactOS. This feature keeps Windows OS files inside a compressed file image. Instead of unpacking it onto the hard drive partition as normal, Windows uncompressed the files that it needs on the fly.
This allows Windows to run on much smaller drives than usual, which is necessary on some systems such as ultrabooks with very small SSDs. We’d say it makes the most sense on systems that have 64GB or less of primary storage space.
Windows usually automatically and silently activates CompactOS on suitable systems. You can however activate it manually, at the cost of slower performance. Since the CPU now has to decompress data as well as do its regular job.
In order to modify anything around CompactOS, you’ll have to use Command Prompt or PowerShell. We prefer PowerShell!
- Simply right-click the start button and select Windows PowerShell (Admin) to open the program.
2. To check if your computer is already running with CompactOS type the following and press enter:
Compact.exe /CompactOS:query
3. If you get a message that CompactOS is already active, there’s nothing more to do. If it isn’t, you can activate it by typing the following and then pressing enter:
Compact.exe /CompactOS:always
It may take a few minutes to complete the compression job, depending on your system specifications.
To disable CompactOS again, use this command:
Compact.exe /CompactOS:never
Shrink Your Virtual Memory Allocation
When your computer runs out of physical RAM, it has to start swapping out data to your hard drive, using something called a paging file. That paging file takes up a reserved amount of space on your hard drive.
You do have some options here. For example, you can disable the paging file entirely. We don’t usually recommend this, but on some systems with plenty of RAM it might not be an issue.
You can simply shrink down the paging file size determined by Windows. The general rule of thumb is that your paging file should be 1.5 times your physical RAM, but that rule can be bent however you like.
Finally, you can move the paging file to a different internal hard drive from the one that Windows is installed on. Which will free up space on the system drive. For all the details on how to fine-tune the size of your paging file, have a look at How To Optimize The Paging File In Windows.
Small Is Beautiful
Windows 10 (and really most versions of Windows) has a reputation for being particularly bloated. Yet, if you nip and tuck things in all the right places then it can be a surprisingly svelte operating system. Just remember not to be too overzealous. You might take something important out by mistake!
