How to Reset WindowsApps folder Permissions to Default

Ramesh

Summary: This article tells you how to reset the WindowsApps folder permissions (and ownership) to Windows default.

The WindowsApps folder under the Program Files folder stores the modern app packages. Each package folder under WindowsApps contains a manifest (named AppxManifest.xml) that contains a special XML namespace for packaged apps. When you reinstall built-in apps using PowerShell add-appxpackage command-line, it uses the corresponding app’s package folder under WindowsApps.

The WindowsApps folder is not browsable in File Explorer by default. This is due to tight permissions assigned to the folder.

To access this folder, many users tend to take ownership of the folder and sub-folders. Some users also change the permissions for this folder and sub-folders arbitrarily, and later observe that some of the installed Store apps fail to work.

Even worse is that some users would reset the permissions for WindowsApps, its subfolders, and files (recursively) using the Icacls.exe reset command-line. This is not recommended, as the WindowsApps folder doesn’t inherit any permission entries from the parent (Program Files) folder by default. Instead, this folder has very restricted permissions, including one or more conditional ACEs.

Restore the Default Permissions for WindowsApps

To reset the WindowsApps folder permissions to Windows default, follow these steps:

Editor’s note: Before proceeding, it’s advisable to take a complete system image backup using Macrium Reflect Free, Acronis True Image, or any other backup tool. This is because if you inadvertently assign the wrong permissions to the WindowsApps folder, it might prevent you from installing and running Store apps.

(The following fix has been tested on Windows 10 versions 2004, 20H2, 21H1, and 21H2.)

Open an admin Command Prompt window, and run the following commands one by one:

Command #1

takeown /f "%programfiles%\WindowsApps"

You should see the following output:

SUCCESS: The file (or folder): "C:\Program Files\WindowsApps" now owned by user "computer_name\user_name".

The above command is to take ownership of the WindowsApps folder. This is required to apply the permissions (in the next step.)

Command #2

cacls "%programfiles%\WindowsApps" /s:"D:PAI(A;;FA;;;S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464)(A;OICIIO;GA;;;S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464)(A;;0x1200a9;;;S-1-15-3-1024-3635283841-2530182609-996808640-1887759898-3848208603-3313616867-983405619-2501854204)(A;OICIIO;GXGR;;;S-1-15-3-1024-3635283841-2530182609-996808640-1887759898-3848208603-3313616867-983405619-2501854204)(A;;FA;;;SY)(A;OICIIO;GA;;;SY)(A;CI;0x1200a9;;;BA)(A;OICI;0x1200a9;;;LS)(A;OICI;0x1200a9;;;NS)(A;OICI;0x1200a9;;;RC)(XA;;0x1200a9;;;BU;(Exists WIN://SYSAPPID))"

When you’re prompted with the question, Are you sure (Y/N)? type Y.

The above command-line, which consists of an SDDL string, applies the Windows-default permission entries for the WindowsApps folder. For an alternate method of the above, see cacls vs. icacls paragraph below.

Command #3

icacls "%programfiles%\WindowsApps" /setowner "nt service\trustedinstaller"

You should see the following output:

processed file: WindowsApps
Successfully processed 1 files; Failed processing 0 files

The above command restores the WindowsApps folder’s ownership back to the TrustedInstaller account, which is the factory default setting.

WindowsApps – Default ACL

Here are the default access control entries (Windows 10 v2004, 20H2, 21H1, and 21H2) for the WindowsApps folder:

NT SERVICE\TrustedInstaller:(F)
NT SERVICE\TrustedInstaller:(OI)(CI)(IO)(F)
S-1-15-3-1024-3635283841-2530182609-996808640-1887759898-3848208603-3313616867-983405619-2501854204:(RX)
S-1-15-3-1024-3635283841-2530182609-996808640-1887759898-3848208603-3313616867-983405619-2501854204:(OI)(CI)(IO)(GR,GE)
NT AUTHORITY\SYSTEM:(F)
NT AUTHORITY\SYSTEM:(OI)(CI)(IO)(F)
BUILTIN\Administrators:(CI)(RX)
NT AUTHORITY\LOCAL SERVICE:(OI)(CI)(RX)
NT AUTHORITY\NETWORK SERVICE:(OI)(CI)(RX)
NT AUTHORITY\RESTRICTED:(OI)(CI)(RX)
BUILTIN\Users:(Rc,S,RD,REA,X,RA)

Note: You can view the permissions for the folder by running the command icacls "c:\program files\windowsapps".

The long SIDs are the Capability SIDs built-in to Windows 10. The Capability SIDs don’t resolve to a friendly account name. For more information, check out the Microsoft article Some SIDs do not resolve into friendly names. Microsoft suggests that you DO NOT DELETE capability SIDs from either the Registry or file system permissions.

Additional Information

CACLS vs. ICACLS

The deprecated tool cacls.exe is superseded by icacls.exe. But cacls.exe still works in Windows 10. In case Microsoft removes cacls.exe in future Windows versions, you can apply the ACLs using this method as an alternative for Command #2 above :

  1. Using Notepad, create a text file with the following contents: 
    windowsapps
D:PAI(A;;FA;;;S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464)(A;OICIIO;GA;;;S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464)(A;;0x1200a9;;;S-1-15-3-1024-3635283841-2530182609-996808640-1887759898-3848208603-3313616867-983405619-2501854204)(A;OICIIO;GXGR;;;S-1-15-3-1024-3635283841-2530182609-996808640-1887759898-3848208603-3313616867-983405619-2501854204)(A;;FA;;;SY)(A;OICIIO;GA;;;SY)(A;CI;0x1200a9;;;BA)(A;OICI;0x1200a9;;;LS)(A;OICI;0x1200a9;;;NS)(A;OICI;0x1200a9;;;RC)(XA;;0x1200a9;;;BU;(Exists WIN://SYSAPPID))
  2. Save the file as acl.txt in a folder — e.g. d:\temp\acl.txt
  3. Next, run the following command-line from an admin Command Prompt: 
    icacls "%programfiles%" /restore d:\temp\acl.txt

    Note: When restoring ACL with icacls.exe, you must mention the parent folder name instead of the folder you want to apply the permissions.

What about the subfolders of WindowsApps?

Most of the sub-folders under WindowsApps are owned by SYSTEM,  some of them are owned by Administrators, and a couple of folders by TrustedInstaller. Here’s a listing from a Windows 10 v20H2 computer:

As you can see, most of the package folders are owned by SYSTEM, some of them by Administrators, and a few are owned by TrustedInstaller.

You can view the owner name of each subfolder by running the command from admin Command Prompt:

dir "%programfiles%\windowsapps" /q /ad

Or, the following command from admin PowerShell prompt:

Get-ChildItem "C:\Program Files\WindowsApps" | Select Name,@{Name="Owner";Expression={(Get-ACL $_.Fullname).Owner}} | format-list

Fixing permissions for the package folders can be done on a per-folder basis rather than changing them en masse.
