您的Windows 10计算机或设备可能使用了很长时间。它安装了许多应用程序和程序，你甚至不记得它们是什么时候到达那里的。您想了解应用程序何时安装在Windows 10中吗？您想知道何时安装了Microsoft Store中的(Microsoft Store)Windows 10应用吗？
重要提示：(IMPORTANT:)本指南涵盖通过Microsoft Store分发的Windows 10应用程序以及您可以从其他任何地方下载和安装的程序或桌面应用程序。如果您想知道何时安装了Windows 10应用程序，第一种方法是唯一可以帮助您的方法。对于桌面应用程序和程序，也请查看其他方法。
使用Windows 10(Windows 10)设置了解程序或应用的安装时间
首先，在Windows 10中(Windows 10)打开“设置”(open the Settings)应用。一种方法是按键盘上的Windows + I键。然后，转到应用程序(Apps)类别。
在左侧的列中，确保选择了应用和功能(Apps & features)。在右侧，Windows 10 显示您的计算机或设备上安装的所有应用程序和程序。
向下滚动(Scroll)右侧的应用程序列表，找到您感兴趣的应用程序。单击或点击其名称，然后查看其大小下方的安装日期，如下面的屏幕截图所示。完成后，您可以关闭设置(Settings)。
重要提示：(IMPORTANT:)此方法的一个缺点是，对于通过Microsoft Store更新的(Microsoft Store)Windows 10应用程序，显示的日期是其上次更新的日期。当Microsoft Store更新应用程序( updates an app)时，Windows 10 将其视为应用程序的新安装，安装日期会相应更改。
提示：(TIP:)如果您想查找您使用的应用程序或程序的确切版本，请参阅如何查找任何 Windows 应用程序的确切版本(how to find the exact version of any Windows application)。
使用控制面板(Control Panel)查看桌面应用程序的安装时间
如果您想知道某个程序（或桌面应用程序）何时安装在Windows 10中，请打开控制面板(open the Control Panel)。在“控制面板(Control Panel)”窗口中，单击“程序”下的“卸载程序("Uninstall a program")”(Programs)链接。或者，您可以转到"Programs -> Programs and Features."
您会看到 Windows 10 PC 上安装的所有桌面程序的列表。找到您感兴趣的程序，然后检查Installed On列。在那里，您可以看到该程序的安装时间。
如果您没有看到此列，请右键单击程序列表中的任何其他列，然后选中“安装在”(Installed On")选项。
重要提示：(IMPORTANT:)此方法的一个缺点是某些桌面应用程序在更新自身时会更改“安装日期” 。("Installed On")因此，您看不到它们的安装时间，而是最后一次安装更新的时间。更令人困惑的是，并非所有程序的行为都相同。由于这个问题，我们更喜欢本指南中的下一个方法，它提供了更可靠的信息。
使用文件资源管理器(File Explorer)查明安装桌面应用程序的时间
首先，打开文件资源管理器(open File Explorer)。一种方法是按键盘上的Windows + E或单击任务栏上的图标。转到这台电脑(This PC)，然后打开安装Windows 10的驱动器。通常，那是C:驱动器。如果您要检查的程序是 32 位程序，请打开Program Files (x86)文件夹。如果是 64 位，请打开Program Files 文件(Program Files)夹。如果您不知道此信息，请一个接一个地打开这两个文件夹，然后查看是否找到该程序的安装文件夹。当您这样做时，右键单击文件夹列表上方的任何列，然后选择Date created。
这会将创建日期(Date created)列添加到为每个文件夹显示的信息中。查找您感兴趣的程序的安装文件夹，并查看它是何时创建的。该日期是程序首次安装的日期。
完成后关闭文件资源管理器(File Explorer)。
提示：(TIP:)如果您想知道您使用的Windows 10应用或程序的大小，请参阅四种方法来了解您的应用使用了多少空间(four ways to find out how much space your apps are using)。
使用PowerShell(PowerShell)查看桌面应用程序的安装时间
此方法返回与控制面板(Control Panel)相同的数据，它可能对喜欢或使用命令行环境的人有用。启动 PowerShell(Start PowerShell)，然后输入不带引号的命令："gp HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall* |Select DisplayName, InstallDate|ogv"。您应该会看到类似于下面的屏幕截图的结果。
请注意，InstallDate在安装每个程序的年、月和日之间没有空格。此外，对于某些桌面应用程序，可能没有提供安装日期，即使该数据显示在其他位置。
您是否知道(Did)何时安装了应用程序或程序？
我希望您发现这些提示很有用。很难找出应用程序安装在 Windows 10 计算机或设备上的确切日期，而这些方法是我们唯一能弄清楚的方法。如果您知道查看程序或应用程序何时安装的其他方法，请不要犹豫，在下面的评论中分享它们。
When was a program or app installed in Windows 10?
You may have your Windows 10 computer or device for a long time. It has many apps and programs іnѕtalled, and you don't еven remember when they got there in the first place. Do you want to find out when an application was installed in Windows 10? Do you want to know when a Windows 10 app from the Microsoft Store was installed?
IMPORTANT: This guide covers both Windows 10 apps distributed through the Microsoft Store and programs or desktop apps that you can download and install from anywhere else. If you want to know when a Windows 10 app was installed, the first method is the only one that helps you. For desktop apps and programs, check out the other methods too.
Find out when a program or app was installed, using Windows 10 Settings
First, open the Settings app in Windows 10. One way to do that is to press the Windows + I keys on your keyboard. Then, go to the Apps category.
In the column on the left, make sure that Apps & features is selected. On the right, Windows 10 displays all the apps and programs installed on your computer or device.
Scroll down the list of apps on the right, and find the one that interests you. Click or tap on its name, and see the installation date beneath its size, like in the screenshot below. When done, you can close the Settings.
IMPORTANT: One downside to this method is that for Windows 10 apps updated through the Microsoft Store, the date shown is the date of their last update. When Microsoft Store updates an app, Windows 10 counts it as a new installation of the app, and the install date changes accordingly.
TIP: If you want to find the exact version of an app or program that you use, see how to find the exact version of any Windows application.
Find out when a desktop app was installed, using Control Panel
If you want to know when a program (or desktop app) was installed in Windows 10, open the Control Panel. In the Control Panel window, click the "Uninstall a program" link under Programs. Alternatively, you can go to "Programs -> Programs and Features."
You are shown a list of all the desktop programs that are installed on your Windows 10 PC. Find the program that you are interested in, and then check the Installed On column. There you see when that program was installed.
If you don't see this column, right-click on any other column from the list of programs, and check the "Installed On" option.
IMPORTANT: One downside to this method is that some desktop apps change the "Installed On" date when they update themselves. Therefore, you don't see when they were installed, but when an update was last installed. To make things even more confusing, not all programs behave the same. Because of this issue, we prefer the next method from this guide, which provides more reliable information.
Find out when a desktop app was installed, using File Explorer
First, open File Explorer. One way to do that is to press Windows + E on your keyboard or click its icon on the taskbar. Go to This PC, and open the drive where Windows 10 is installed. Usually, that's the C: drive. If the program that you want to check is a 32-bit one, open the Program Files (x86) folder. If it is a 64-bit one, open the Program Files folder. If you don't know this information, open both folders one after the other, and see if you find the program's installation folder. When you do, right-click on any of the columns above the folders list, and select Date created.
This adds the Date created column to the information shown for each folder. Look for the installation folder of the program that you are interested in, and see when it was created. That date is the date when the program was first installed.
Close File Explorer when done.
TIP: If you want to know the size of a Windows 10 app or program that you use, see four ways to find out how much space your apps are using.
Find out when a desktop app was installed, using PowerShell
This method returns the same data as the Control Panel, and it may be useful for people who love or use command-line environments. Start PowerShell, and enter this command without the quotation marks: "gp HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall* |Select DisplayName, InstallDate|ogv". You should see a result similar to the screenshot below.
Notice that the InstallDate is written without spaces between the year, the month, and the day when each program was installed. Also, for some desktop applications, there may be no installation date provided, even though that data is displayed in other places.
Did you find out when an app or program was installed?
I hope that you found these tips useful. It is difficult to find out the exact date when an app got installed on your Windows 10 computer or device, and these methods are the only ones we could figure out. If you know other ways to see when a program or app was installed, don't hesitate to share them in a comment below.
