OneDrive可以完美地使用云技术扩展您的计算机存储空间。您也不需要创建另一个帐户，因为您使用Microsoft 帐户登录^{(Microsoft account)}OneDrive。

虽然您一次只能在OneDrive上登录一个^(OneDrive)Microsoft帐户，但您可以在OneDrive网站上使用其他Microsoft帐户。这是一种有用的接触，但有时会让人感到困惑。例如，如果您已将OneDrive链接到多个Microsoft帐户，您可能会忘记哪个帐户在哪个设备上登录。

本简要指南将向您展示如何随时确认您在OneDrive中使用的Microsoft帐户。

找出^(Find)我在OneDrive中使用的Microsoft 帐户^{(Microsoft Account)}

要确认您当前在OneDrive上使用的特定Microsoft帐户，请使用CID。CID是一个 16 位十六进制数字的字符串，您可以在多个地方找到它。

对于本指南，我们将从以下目录中的OneDrive 设置文件夹中获取它：^{(OneDrive Settings)}

C:\Users\{user}\AppData\Local\Microsoft\OneDrive\settings\Personal

在这里，找到 .INI 和 .DAT 文件，并注意它们的名称。

.ini 或 .dat 之前的文件名部分是CID。

在图像中，您将看到它是 7b3a32094c7650f1。

获得 CID 后，按 Windows + R组合打开“运行”^(Run)对话框。

键入regedit并按ENTER打开Windows 注册表编辑器^{(Windows Registry Editor)}。

在注册表编辑器^{(Registry Editor)}中，转到以下文件夹：

HKEY_CURRENT_USER\Software\Microsoft\IdentityCRL\UserExtendedProperties

单击^(Click)此文件夹中的电子邮件地址，您将在右侧窗格中看到该帐户的CID 。如果您在此处发现多个电子邮件帐户，请一一单击以记下CID。

这样您就可以轻松判断您在OneDrive中使用的是哪个^(OneDrive)Microsoft帐户。

How to find out which Microsoft Account I am using with OneDrive

OneDrive works perfectly to expand your computer’s storage using cloud tech. You also don’t need to create another account, because you sign in to your OneDrive using a Microsoft account.

While you can only sign in to one Microsoft account on OneDrive at a time, you can use other Microsoft accounts on the OneDrive website. This is a useful touch, but it gets confusing sometimes. For instance, if you’ve linked your OneDrive to multiple Microsoft accounts, you can lose track of which account is logged in on what device.

This brief guide will show you how to confirm the Microsoft account you are using with OneDrive at any time.

Find out which Microsoft Account I am using with OneDrive

To confirm the specific Microsoft account you’re currently using on OneDrive, you use the CID. The CID is a string of 16 hex digits, and you can find it in several places.

For this guide, we’ll get it from the OneDrive Settings folder in the following directory:

C:\Users\{user}\AppData\Local\Microsoft\OneDrive\settings\Personal

Here, find the .INI and .DAT files, and watch out for their names.

The portion of the file names before the .ini or .dat is the CID.

In the image, you will see that it is 7b3a32094c7650f1.

Having got the CID, press the Windows + R combination to open the Run dialog box.

Type regedit and press ENTER to open the Windows Registry Editor.

In the Registry Editor, go to the following folder:

HKEY_CURRENT_USER\Software\Microsoft\IdentityCRL\UserExtendedProperties

Click on the email address in this folder, and you’ll see the CID for the account shown on the right-hand pane. If you find more than one email account here, click them one by one to note the CID.

That is how you can tell which Microsoft account you’re using with OneDrive, easily.
