If you’ve ever tried to open the WindowsApps folder in Windows 10 or Windows 11, you’ve probably run into an “Access Denied” message. This folder is one of the most protected locations in Windows because it stores files related to Microsoft Store apps, built-in applications, and other important system components. Microsoft restricts access to prevent accidental changes that could cause apps to stop working properly.
The good news is that you can safely gain access to the WindowsApps folder if you follow the correct steps. Whether you’re troubleshooting an application, backing up files, or trying to locate app data, this guide will walk you through the entire process in a beginner-friendly way.
The WindowsApps Folder
The WindowsApps folder is typically located inside the Program Files directory. By default, the folder is hidden and protected by the TrustedInstaller account. Even users with administrator privileges may be blocked from opening it.
When you attempt to access the folder, Windows displays an error because your account does not have the necessary ownership and permissions. The solution involves changing ownership of the folder and granting your account the required access rights.
Before proceeding, remember that modifying files inside the WindowsApps folder can affect Microsoft Store applications.
It is best to make changes only when necessary and avoid deleting files unless you know exactly what they do.
Fix Cannot Access WindowsApps Folder in Windows 10/11
To fix the Cannot Access WindowsApps Folder issue in Windows 10 or Windows 11:
- Open File Explorer and enable hidden items.
- Navigate to the WindowsApps folder location.
- Open the folder’s Properties and access Advanced Security Settings.
- Change the folder owner from TrustedInstaller to your user account.
- Apply the changes and grant yourself full permissions.
- Reopen the folder and verify access.
- Use Command Prompt or PowerShell if permission changes do not work.
Let’s learn the process in detail!
Step 1: Enable Hidden Files and Locate the WindowsApps Folder
The first thing you need to do is make the WindowsApps folder visible. Since the folder is hidden by default, you won’t be able to see it unless hidden items are enabled in File Explorer.
Open File Explorer and navigate to your C: drive. Click the View menu at the top of the window. In Windows 11, select Show and then enable Hidden Items. In Windows 10, simply check the Hidden items option in the ribbon menu.
Once hidden items are visible, open the Program Files folder. You should now see a folder named WindowsApps. If you attempt to open it at this stage, Windows will likely display an ” Access Denied ” message. This is normal and simply confirms that folder protection is active.
Making the folder visible is an important first step because it allows you to access the security settings needed for the next stages of the process.
Step 2: Take Ownership of the WindowsApps Folder
The most common reason users cannot access the WindowsApps folder is that it is owned by TrustedInstaller rather than a standard administrator account.
Right-click the WindowsApps folder and select Properties. Next, click the Security tab and then choose Advanced. At the top of the window, you will see the current owner listed as TrustedInstaller.
Click Change next to the owner field. In the box provided, type the name of your Windows user account. You can also click Advanced and then Find Now to locate your account from the list.
After selecting your account, click OK. Enable the option labeled Replace owner on subcontainers and objects if available. Then click Apply.
Windows may take several moments to process the ownership change, especially if the folder contains a large number of files. Once completed, your account will become the new owner of the folder.
Ownership is important because Windows uses it as the foundation for determining who can manage permissions and access protected content.
Step 3: Grant Full Control Permissions
Changing ownership alone may not provide immediate access. You also need to assign the proper permissions to your user account.
Return to the Security tab of the folder properties. Click Edit and then choose Add if your account is not already listed. Select your account and enable Full Control under the permissions section.
Click Apply and then OK to save the changes.
If your account is already listed, verify that Full Control is checked. Without full permissions, Windows may still block access to some files and folders inside WindowsApps.
Once permissions are updated, close all open windows and try reopening the folder. In many cases, you will now have complete access.
This step ensures that Windows recognizes your account as having authority to view and manage the contents of the folder.
Step 4: Use an Administrator Account
Sometimes permission changes fail because the account acting lacks administrative privileges.
To verify your account status, open Settings, select Accounts, and navigate to Your Info. If your account is listed as an administrator, you can continue with the process. If not, sign in using an administrator account or ask a system administrator to perform the changes.
Administrative privileges give your account additional authority when working with protected system folders. Without these rights, ownership and permission modifications may not be applied correctly.
After confirming administrator access, repeat the ownership and permission steps if necessary.
Many access issues are resolved simply by using an account that has the proper administrative permissions.
Step 5: Access the Folder Through PowerShell
If File Explorer continues to deny access, PowerShell can sometimes help verify permissions and provide another way to work with the folder.
Open Windows PowerShell as Administrator by searching for PowerShell in the Start menu and selecting Run as administrator.
You can then navigate to the folder using commands and confirm whether the permission changes have been successfully applied.
PowerShell is particularly useful for advanced troubleshooting because it provides more detailed error messages than File Explorer. These messages can help identify whether ownership, permissions, or another security setting is causing the problem.
For many users, PowerShell serves as a valuable backup method when graphical tools do not work as expected.
Step 6: Check for Security Software Restrictions
Some antivirus programs and endpoint security tools may restrict access to protected Windows folders.
If you continue receiving access denied messages after changing ownership and permissions, temporarily review your security software settings. Certain programs monitor system directories and may block access attempts even when Windows permissions are correctly configured.
Check whether your antivirus has file protection or ransomware protection features enabled. If necessary, temporarily disable the relevant protection feature, test access to the folder, and then re-enable protection afterward.
This step should always be performed carefully and only for troubleshooting purposes.
Step 7: Restore Default Permissions If Needed
If you gain access but later experience problems with Microsoft Store apps, restoring the original permissions may help.
The WindowsApps folder is designed to be managed by TrustedInstaller. Returning ownership to this account can restore the default security configuration and reduce the risk of application issues.
You can return to the Advanced Security Settings window and change the owner back to NT SERVICE\TrustedInstaller if necessary.
Restoring the original configuration is often recommended after troubleshooting is complete, especially on production systems where stability is important.
Additional Tips
Always create a System Restore Point before changing permissions on protected Windows folders. This provides a recovery option if something unexpected occurs.
Avoid deleting files from the WindowsApps folder unless you are certain of their purpose. Many Microsoft Store apps rely on these files to function correctly.
Keep your Windows installation updated because some permission-related issues are fixed through cumulative updates.
Use a dedicated administrator account for advanced system maintenance tasks rather than making permanent changes to your everyday user account.
If you only need access to application data, check whether the app stores information in another location, such as AppData, which may be easier and safer to access.
