如果您打算在 Windows 机器上找到计算器来执行重要计算，您可能正在阅读这篇文章，但经过一番搜索后，您意识到您的计算器程序^{(calculator program)}丢失了！

很奇怪^{(Pretty weird)}吧？发生这种情况的原因有很多，但基本上你的计算器不见了！如果您最近在Windows XP上安装了^{(Windows XP)}服务包^{(service pack)}，例如SP2 或 SP3^{(SP2 or SP3)}，那可能是罪魁祸首。如果您从Windows 7或 Windows 8 升级到Windows 10，这也可能是原因。

无论哪种方式，这里有几种方法可以让您的计算器恢复到Windows XP和更高版本。

方法 1 ^{(Method 1)} – 重新安装计算器^{(– Reinstall Calculator)}( Windows XP )

只要您有Windows CD ，第一种方法就非常简单。将其弹出到磁盘驱动器^{(disk drive)}并转到控制面板^{(Control Panel)}。现在转到Add/Remove Programs，单击 Add/Remove Windows 组件^{(Windows Components)}。

单击附件和实用程序^{( Accessories and Utilities)}，然后单击下面的详细信息^(Details)按钮：

现在单击附件^{(Accessories)}，然后再次单击详细信息^(Details)按钮。现在确保选中计算器^(Calculator)框。

现在一直单击确定，XP 将继续并重新安装计算器！如果您无法获得Windows XP 光盘^{(Windows XP disc)}，请尝试第二种方法。

方法 2 ^{(Method 2)} – 复制 calc.exe^{(– Copy calc.exe)}（所有Windows 版本^{(Windows Versions)}）

恢复Calculator^(Calculator)的第二种方法可能是更简单的方法，即简单地将calc.exe文件从另一台机器复制到C:\Windows\System32文件夹。此外，将calc.chm复制到c:\Windows\Help。

显然，您会在另一台运行计算器的计算机上的这两个目录中找到这两个文件。之后，您可以在“开始”菜单或任何您喜欢的地方创建calc.exe文件^{(Start Menu)}的快捷方式。^{(calc.exe file)}如果您找不到CHM 文件^{(CHM file)}，请不要担心，您真正需要的只是EXE 文件^{(EXE file)}。

如果在尝试复制到System32目录时收到^(System32)错误消息^{(error message)}，则需要确保以管理员身份打开Windows 资源^{(Windows Explorer)}管理器。

为此，请单击Start，输入Explorer，然后右键单击Windows Explorer并选择Run as Administrator。在Windows 10中，右键单击资源管理器（运行命令）^{(Explorer (Run Command))}选项。

使用管理员权限的资源管理器窗口^{(Explorer window)}，您现在应该能够将calc.exe 文件^{(calc.exe file)}复制并粘贴到System32 目录^{(System32 directory)}中。

方法 3^{(Method 3)} –从Microsoft下载计算器^{(– Download Calculator)}

如果由于某种原因，您无法让Calculator在您的系统上运行，只需从Microsoft下载它（现在它只能从CNET获得）。这适用于所有版本的Windows。

一旦你下载并安装它，你可能会对默认设置的可怕 UI 感到震惊。它是紫色的，有椭圆形的纽扣，看起来很糟糕。

值得庆幸的是，您可以单击“查看”^(View)，然后选择“经典视图”^{( Classic View)}以获得正常外观的计算器版本。如果您不喜欢Windows 8和Windows 10附带的计算器应用程序^{(Calculator app)}，您可以随时下载此版本并使用它。

您也可以单击查看^(View)并选择标准^(Standard)以删除左侧的转换选项，而只保留旧的标准计算器^{(standard calculator)}。

在Windows 10中，计算器应用程序^{(calculator app)}应已默认安装。如果没有，您可以从 Microsoft Store 下载计算器应用程序^{(calculator app from the Microsoft Store)}。

方法 4 – 使用 CD 和 SFC

如果您有Windows XP CD，您也可以尝试将 CD 弹出并运行这两个命令，其中 X 是您的CD/DVD drive盘符。

expand -r X:\I386\calc.ex_ c:\windows\system32
expand -r X:\I386\calc.ch_ c:\windows\help

如果您没有运行Windows XP，您可以尝试运行系统文件检查器^{(system file checker)}( SFC )，这是一个内置命令，可检查所有系统文件以确保它们存在且未损坏。您可以阅读我之前关于如何在Windows中使用^(Windows)SFC 命令^{(SFC command)}的帖子。如果您有任何问题，请随时发表评论。享受！

Windows Calculator Missing or Disappeared?

You’re probablу reading this article if you wеre going to fіnd the calculatоr on уour Windows machine to perform an important calculation, but aftеr a bit of searching you rеalized that your calculator program is missing!

Pretty weird right? Well this can happen for a number of reasons, but basically your calculator is gone! If you recently installed a service pack to Windows XP, such as SP2 or SP3, that could be the culprit. If you upgraded from Windows 7 or Windows 8 to Windows 10, that could also be the cause.

Either way, here are a couple of ways you can get your calculator back in Windows XP and higher.

Method 1 – Reinstall Calculator (Windows XP)

The first method is pretty straight-forward as long as you have your Windows CD. Pop it into the disk drive and go to the Control Panel. Now go to Add/Remove Programs, click on Add/Remove Windows Components.

Click on Accessories and Utilities and then click the Details button below:

Now click on Accessories and click the Details button again. Now make sure to check the Calculator box.

Now click OK all the way back and XP will go ahead and reinstall the calculator! If you can’t get a hold of a Windows XP disc, then try the second method.

Method 2 – Copy calc.exe (All Windows Versions)

The second way to get Calculator back and probably the easier method is to simply copy the calc.exe file over from another machine to your C:\Windows\System32 folder. Also, copy calc.chm to c:\Windows\Help.

Obviously, you’ll find both of these files in those two directories on another computer that has the calculator working. After that, you can just create a shortcut to the calc.exe file on your Start Menu or wherever you like. If you can’t find the CHM file, don’t worry, all you really need is the EXE file.

If you get an error message when trying to copy to the System32 directory, you need to make sure you open Windows Explorer as an administrator.

To do that, click on Start, type in Explorer and then right-click on Windows Explorer and choose Run as Administrator. In Windows 10, right-click on the Explorer (Run Command) option.

With an administrator rights Explorer window, you should now be able to copy and paste the calc.exe file into the System32 directory.

Method 3 – Download Calculator from Microsoft

If for some reason, you can’t get Calculator working on your system, just download it from Microsoft (now it’s only available from CNET). This works on all versions of Windows.

Once you download and install it, you’ll probably be shocked by the horrible UI that is set by default. It’s purple and has oval buttons and looks terrible.

Thankfully, you can click on View and then choose Classic View to get a normal looking version of the calculator. If you don’t like the Calculator app that comes with Windows 8 and Windows 10, you can always download this version and use it instead.

You can also click on View and choose Standard to remove the conversion options on the left and just have the old standard calculator.

In Windows 10, the calculator app should already be installed by default. If not, you can download the calculator app from the Microsoft Store.

Method 4 – Use CD and SFC

If you have a Windows XP CD, you can also try popping the CD in and running these two commands, where X is your CD/DVD drive letter.

expand -r X:\I386\calc.ex_ c:\windows\system32
expand -r X:\I386\calc.ch_ c:\windows\help

If you’re not running Windows XP, you can try running system file checker (SFC), which is a built-in command that checks all the system files to make sure they exist and are not corrupt. You can read my previous post on how to use the SFC command in Windows. If you have any questions, feel free to comment. Enjoy!
