如果您出于某种原因不得不更改Windows 11/10中文件和文件夹的权限，并且您想将权限重置为默认值，这篇文章将对您有所帮助。其中一位用户报告说，他必须为每个人设置所有权和权限，并完全控制特定任务，现在已经完成，恢复默认权限很困难。由于该选项未内置于系统中，我们将不得不使用secedit  和icacls命令重新配置。

如何将文件^(File)和文件夹^(Folder)权限重置为默认值

安全性至关重要，不仅其他用户可以访问文件，而且您安装在计算机上的程序也可以获得相同的访问权限。好消息是修复默认权限很容易，您只需要运行一个命令行程序来修复它。在继续之前，请创建一个系统还原点^{(system restore point)}，以便万一出现问题，您可以还原。

1. 运行 icacls 命令
2. 运行 Secedit 命令

您需要管理员权限才能执行命令。

1]运行icacls命令

使用 icacls 命令解决此问题的另一种方法。但是，您需要首先获得该文件夹的所有权，^{(take ownership of the folder)} 然后执行该命令。Windows 使用访问控制列表^{(Access Control List)}来配置所有文件和文件夹的权限。icacls是一个命令行实用程序^{(command-line utility)}，可以显示和修改指定文件的权限并应用它们。

它带有一个重置选项，可将所有匹配文件的 ACL 替换为^(ACLs)默认继承的ACL^(ACLs)。我们将使用以下选项进行重置

• t - 对当前目录及其子目录中的所有指定文件进行操作。
• q - 抑制成功消息。
• c - 尽管有任何文件错误，仍继续操作。仍然会显示错误消息。^(Error)

接下来，在提升的命令提示符下运行以下命令-

icacls * /t /q /c /reset

完成后，您必须将权限保存到文件中，以便以后再次使用或应用于其他计算机。

2]运行Secedit命令

它允许您通过将当前配置与模板进行比较来配置和分析系统安全性。

通过将您当前的安全配置与指定的安全模板进行比较来配置和分析系统安全。

^{(Type CMD)}在运行^(Run)( Win +R键入 CMD ，然后按Shift + Enter以管理员权限打开它

执行以下命令-

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

您可能会收到一些警告，但您可以放心地忽略它。

在Windows^(Windows)上更改权限很棘手，因为一旦您更改它，就无法切换回默认权限。它应该从一开始就在那里，让Windows 用户^(users)自己修复它。

我希望这些命令有用并帮助您将文件和文件夹权限重置为Windows中的默认值。

How to reset File and Folder permissions to default in Windows 11/10

If you had to change the permissions of files and folders in Windows 11/10 for some reаѕon, and if you want tо reset the permissions to default, this post will help yoυ. One of the users reported that he had to set the ownerѕhip and permissions to everyone and full control for a specific task, and now that it’s donе, gettіng back to the default permission is difficult. Since the option is not bυilt into the system, we will have to usе the secedit  and icacls commands to reconfigure.

How to reset File & Folder permissions to default

Security is essential, and it is not just that other users can access the files, but programs you install on the computer also get the same access.  The good news is that fixing the permissions to default is easy, and all you need is to run a command-line program to fix it. Before going ahead, create a system restore point, so in case things go wrong, you can restore.

1. Run icacls command
2. Run Secedit command

You will need admin permission to execute the commands.

1] Run icacls command

Another method to resolve this using the icacls command. However, you will need first to take ownership of the folder and then execute the command. Windows uses the Access Control List to configure permissions for all files and folders. Icacls is a command-line utility that can display and modify the permissions on specified files and apply them.

It comes with a reset option that replaces ACLs with default inherited ACLs for all matching files. We will use the following options to reset

• t—Operates on all specified files in the current directory and its subdirectories.
• q—Suppresses success messages.
• c—Continues the operation despite any file errors. Error messages will still be displayed.

Next, run the following on an elevated command prompt—

icacls * /t /q /c /reset

Once done, you must save the permission into a file that you can use again later or apply to other computers.

2] Run Secedit command

It allows you to configure and analyze system security by comparing the current config with a template.

Configures and analyzes system security by comparing your current security configuration against specified security templates.

Type CMD in the Run (Win +R) prompt and then press Shift + Enter to open it with admin permission

Execute the following command-

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

You may get some warning, but you can safely ignore it.

Changing permission on Windows is tricky because there is no way to switch back to default permission once you change it. It should have been there right from the start and let Windows users fix it themselves.

I hope these commands were useful and helped you reset file & folder permissions to default in Windows.
