CMD 安全修复指南

① 关闭 OneDrive

中文说明

打开 CMD（命令提示字元），普通权限即可。

执行：

taskkill /f /im OneDrive.exe

如果显示找不到 OneDrive 进程，不用担心，继续下一步即可。

🇬🇧 English

Open Command Prompt (CMD). Normal user permission is sufficient.

Run:

taskkill /f /im OneDrive.exe

If Windows says that the OneDrive process could not be found, don’t worry. Continue to the next step.

② 重置 OneDrive

中文说明

在 CMD 执行：

%localappdata%\Microsoft\OneDrive\OneDrive.exe /reset

等待 2–3 分钟。不要马上重复执行。

然后启动 OneDrive：

start "" "%localappdata%\Microsoft\OneDrive\OneDrive.exe"

检查 OneDrive 是否重新出现，然后尝试登录。

🇬🇧 English

In CMD, run:

%localappdata%\Microsoft\OneDrive\OneDrive.exe /reset

Wait for 2–3 minutes. Do not run the command repeatedly.

Then start OneDrive:

start "" "%localappdata%\Microsoft\OneDrive\OneDrive.exe"

Check whether the OneDrive icon appears again and try signing in.

③ 如果仍然出现 0x8004DEEF

中文说明

如果 OneDrive 仍然无法登录，并显示：

Error Code: 0x8004DEEF

继续执行以下命令：

del /f /q "%localappdata%\Microsoft\OneDrive\settings\PreSignInSettingsConfig.json"

如果出现：

Could Not Find...

不用担心。

这表示该文件不存在，可以继续下一步。

然后执行：

%localappdata%\Microsoft\OneDrive\OneDrive.exe /reset

等待约 2 分钟。

再执行：

start "" "%localappdata%\Microsoft\OneDrive\OneDrive.exe"

然后再次尝试登录。

🇬🇧 English

If OneDrive still cannot sign in and shows:

Error Code: 0x8004DEEF

Run:

del /f /q "%localappdata%\Microsoft\OneDrive\settings\PreSignInSettingsConfig.json"

If you see:

Could Not Find...

Don’t worry.

It simply means that the file does not exist. Continue to the next step.

Then run:

%localappdata%\Microsoft\OneDrive\OneDrive.exe /reset

Wait approximately 2 minutes.

Then run:

start "" "%localappdata%\Microsoft\OneDrive\OneDrive.exe"

Try signing in again.

④ 检查 Windows 登录凭证

中文说明

如果还是无法登录，可以检查 Windows 储存的登录凭证。

执行：

cmdkey /list

可能会看到类似：

Target: MicrosoftAccount:user=xxxx
Target: OneDrive Cached Credential
Target: MicrosoftOffice16_Data:...

暂时不要删除任何凭证。

把 cmdkey /list 的完整结果复制出来，我们可以先确认哪些项目与 OneDrive / Microsoft 365 有关。

🇬🇧 English

If OneDrive still cannot sign in, we can check the credentials stored in Windows.

Run:

cmdkey /list

You may see entries such as:

Target: MicrosoftAccount:user=xxxx

Target: OneDrive Cached Credential

Target: MicrosoftOffice16_Data:...

Do not delete any credentials yet.

Copy the complete result of cmdkey /list and check which entries are related to OneDrive / Microsoft 365 before removing anything.

⚠️ 重要 / Important

目前不要执行以下操作：

rd /s /q "%localappdata%\Microsoft\OneDrive"

也不要删除 OneDrive 文件夹：

C:\Users\你的用户名\OneDrive

不要直接移除：

Settings → Accounts → Access work or school

🇬🇧 English

Do NOT perform the following actions at this stage:

Do not run:

rd /s /q "%localappdata%\Microsoft\OneDrive"

Do not delete your OneDrive folder:

C:\Users\YourUsername\OneDrive

Do not remove the account from:

Settings → Accounts → Access work or school

This is especially important if the computer is connected to a company Microsoft 365 Business account, because OneDrive, Office, Teams and SharePoint may share the same authentication environment.
