损坏权限:重新获得对文件夹及其子对象的访问权

虽然这个问题的大部分答案都有一定的价值，但恕我直言，没有一个答案是完整的。下面(可能)是Windows 7的一个完美的解决方案，如果你被损坏的权限设置锁定的文件夹:

icacls "c:\folder" /remove:d /grant:r Everyone:(OI)(CI)F /T  

对于Windows 10，用户/SID必须在/remove:d选项后指定:

icacls "c:\folder" /remove:d Everyone /grant:r Everyone:(OI)(CI)F /T  

． 注:

The command is applied to the specified directory. Specifying the user "Everyone" sets the widest possible permission, as it includes every possible user. The option "/remove:d" deletes any explicit DENY settings that may exist, as those override explicit ALLOW settings: a necessary preliminary to creating a new ALLOW setting. This is only a precaution, as there is often no DENY setting present, but better safe than sorry. The option "/grant" creates a new ALLOW setting, an explicit permission that replaces (":r") any and all explicit ALLOW settings that may exist. The "F" parameter (i.e. the permission created) makes this a grant of FULL control. The "/T" parameter adds recursion, applying these changes to all current sub-objects in the specified directory (i.e. files and subfolders), as well as the folder itself. The "(OI)" and "(CI)" parameters also add recursion, applying these changes to sub-objects created subsequently. .

上面的Windows 10命令行是今天好心推荐给我的，所以就在这里。我还没有Windows 10来测试它，但是如果你有的话请尝试一下(然后请在下面发表评论)。

第一步更改只涉及删除DENY设置。可能没有任何DENY设置，所以该选项可能没有区别。我的理解是，在Windows 7上，你不需要在/remove:d后指定用户，但我可能错了!

用户astark建议将Everyone替换为术语*S-1-1-0，以便命令独立于语言。我只有英文版的Windows安装，所以我不能测试这个建议，但它似乎是合理的。

我有很多脚本使用调用，我把它们移动到icacls 我怎么也找不到一个脚本来改变根挂载卷的例子:d:\datafolder。我最终创建了下面的脚本，它将卷作为临时驱动器挂载，然后应用，然后卸载它。这是我发现可以更新根挂载安全性的唯一方法。

1获取文件夹挂载GUID到临时文件，然后读取GUID将卷挂载为临时驱动器X:应用sec并记录更改，然后仅从X:驱动器卸载卷，这样挂载的文件夹除了应用sec之外不会被更改或中断。

以下是我的脚本示例:

**mountvol "d:\%1" /L >tempDrive.temp && FOR /f "tokens=*" %%I IN (tempDrive.temp) DO mountvol X: %%I 
D:\tools\security\icacls.exe  %~2 /grant domain\group:(OI)(CI)F /T /C >>%~1LUNsec-%TDWEEK%-%TMONTH%-%TDAY%-%TYEAR%-%THOUR%-%TMINUTE%-%TAM%.txt
if exist x:\*.* mountvol X: /d**

我为此挣扎了一段时间，只有结合这个帖子中的答案对我有效(在Windows 10上): 1. 打开cmd或PowerShell，进入有文件的文件夹 2. takeown /R /F 3.icacls * /T /grant dan:F

好运！

Windows 10中没有“c:>”和“>”

例如:

F = Full Control
/e : Edit permission and kept old permission
/p : Set new permission

/e /p用户名:F

(这也修复了错误2502和2503)

C:\Windows\Temp /e /p用户名:F

我无法打开驱动器中的任何文件，这个命令解锁了所有-

icacls i:\* /grant Users:F /t /q /c

批量文件夹创建和授予权限的工作我使用下面的powershell脚本。

Import-Csv "D:\Scripts\foldernames.csv" | foreach-object {
    $username = $_.foldername 

    # foldername is the header of csv file

    $domain = “example.com”

    $folder= "D:\Users"

    $domainusername = $domain+“\”+$username

    New-Item $folder\$username –Type Directory

    Get-Acl $folder\$username  

    $acl = Get-Acl $folder\$username

    $acl.SetAccessRuleProtection($True, $False)

    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Administrators","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
    $acl.AddAccessRule($rule)

    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("SYSTEM","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
    $acl.AddAccessRule($rule)

    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("$domain\Domain Admins","Read", "ContainerInherit, ObjectInherit", "None", "Allow")
    $acl.AddAccessRule($rule)

    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule($domainusername,"Modify", "ContainerInherit, ObjectInherit", "None", "Allow")
    $acl.AddAccessRule($rule)

    Set-Acl $folder\$username $acl
}

注意:您必须在csv文件中创建相同的域用户名，否则您将遇到权限问题
