Windows App Corner 'X': What It Means and How to Use It Effectively

Table of Contents

The introduction of Windows 8 and Windows 8.1 brought a significant shift in the user interface, centered around the touch-friendly Start screen featuring dynamic tiles. These tiles represented modern applications, designed specifically for this new environment and distributed primarily through the Microsoft Store. Users interacting with this interface sometimes encountered a peculiar visual anomaly: a small ‘x’ symbol appearing in the lower-right corner of one or more app tiles.

This seemingly minor visual quirk is, in fact, an indicator of an underlying issue that prevents the affected application from launching correctly. Attempting to open an app tile marked with this ‘x’ does not result in the application starting as expected. Instead, users are met with an error message clearly stating the problem: “This app can’t open.” The message typically provides a suggestion to “Check the Microsoft Store for more info about <AppName>,” often including a direct link to “Go to the Store.” This indicates a fundamental problem with the app’s installation or integrity within the operating system.

Understanding the Symptom: The ‘X’ on the App Tile¶

The ‘x’ icon serves as a quick visual cue that the corresponding application is in a non-functional state. On the vibrant and dynamic Start screen, where app tiles are meant to display live information and provide immediate access, a static tile marked with an ‘x’ stands out as an indication of failure. This symptom can affect just a single application, a specific group of apps, or in some cases, a substantial portion of the installed modern apps on the system.

When a user clicks or taps an app tile displaying the ‘x’, the system attempts to launch the associated application. However, due to the underlying issue indicated by the ‘x’, this launch fails. The operating system then presents the user with a standardized error dialog. This dialog explicitly states that the app cannot open and directs the user towards the Microsoft Store, suggesting that the store might hold information or potential solutions related to the specific application in question. The uniformity of this error message across different affected apps suggests a common failure mechanism related to the app’s package or installation status.

Identifying the Potential Causes¶

Several factors can contribute to the appearance of the ‘x’ on app tiles and the subsequent inability to launch the applications. Understanding the potential causes is crucial for effective troubleshooting. The primary suspects generally fall into categories related to the application’s installation process and the overall health of the operating system’s components responsible for managing these modern apps.

One significant cause is attributed to errors that may have occurred when the application package was initially installed. Modern Windows apps are distributed as packages (typically .appx or .appxbundle files). The installation process involves registering the app and its components with the system. If this process is interrupted, encounters corruption, or fails in any way during the initial setup or injection into a Windows image (in deployment scenarios), the app might be left in a broken state, symbolized by the ‘x’. This could happen due to file corruption, permission issues, or conflicts during installation.

Another contributing factor can be out-of-date software components within the operating system itself. The framework and runtime environments required for Windows 8/8.1 apps to function properly rely on various system files and updates. If these underlying components are not current, it can lead to compatibility issues or failures when the system attempts to execute the app code. Outdated dependencies are a common source of software conflicts, and modern apps are no exception. Ensuring the operating system is fully updated is a standard first step in resolving many app-related issues.

Furthermore, the issue is also noted to potentially occur after performing a system refresh using the push-button reset features available in Windows 8 and 8.1. While a system refresh is designed to reinstall Windows while preserving user data, the process of reinstating applications can sometimes lead to inconsistencies or errors, particularly with pre-installed or re-registered modern apps. The integrity of the app packages and the success of their re-registration during the refresh process are critical, and failures here can manifest as the ‘x’ icon.

Troubleshooting and Resolution Steps¶

Fortunately, the issue of the ‘x’ on app tiles and the “This app can’t open” error can often be resolved through a series of troubleshooting steps, ranging from simple patience to more involved system maintenance. It is recommended to attempt these solutions in sequence, as they progress from the least disruptive to potentially more complex interventions.

Step 1: Allow the System Time to Recover¶

Sometimes, the issue may be temporary and related to background processes or system checks that are automatically running. Windows has built-in mechanisms designed to detect and potentially self-heal certain types of errors. In some cases, simply waiting several minutes may allow the operating system to correct the problem in the background. This is the least intrusive step and requires no user action beyond observing if the ‘x’ icons disappear on their own. While not always effective for persistent issues, it is a simple initial consideration.

Step 2: Check for and Install Windows Updates¶

Keeping the operating system updated is fundamental to maintaining system stability and ensuring compatibility with applications. Windows Updates often include fixes for known issues, updates to system components, and improvements to runtime environments that are critical for modern apps. An outdated system could be missing crucial patches required for app functionality or installation integrity. Checking for and installing the latest updates is a vital troubleshooting step.

To check for updates in Windows 8.1:

1. Access the Charms bar by swiping in from the right edge of the screen (on touch devices) or by pointing the mouse cursor to the lower-right or upper-right corner and moving it slightly upwards or downwards.
2. Tap or click on Settings.
3. Select Change PC settings at the bottom of the Settings pane.
4. In PC Settings, navigate to Update and recovery.
5. Under Windows Update, tap or click Check now. Windows will scan for available updates.
6. If updates are found, tap or click Install updates.
7. Review and accept any license terms if prompted.
8. Follow any on-screen instructions, which may include restarting your computer to complete the installation.

Installing pending updates can resolve underlying system issues that were preventing apps from functioning correctly or were causing the ‘x’ icon to appear.

Step 3: Address the Applications Directly¶

If updating Windows does not resolve the problem, the issue might be more directly related to the affected applications or shared components they rely on. The next step involves interacting with the applications themselves, specifically through the Microsoft Store. This could involve updating the apps or, if updating isn’t possible or effective, uninstalling and then reinstalling them.

Many modern apps share common dependencies and runtime libraries. An issue with one shared component could affect multiple applications. Installing a new app from the Store, or updating/reinstalling an existing one, might trigger an update or repair process for these shared dependencies, inadvertently fixing the issue for other affected apps as well.

To manage apps via the Microsoft Store:

1. Open the Microsoft Store from the Start screen.
2. Access the Charms bar (swipe from right or mouse to corner).
3. Tap or click Settings.
4. Tap or click App updates.
5. Tap or click Check for updates. Install any available app updates.

If updating specific affected apps does not work, consider uninstalling and reinstalling them:

1. Go to the Start screen.
2. Right-click (or press and hold on touch) on the app tile displaying the ‘x’.
3. From the context menu that appears, select Uninstall. Confirm the action if prompted.
4. Once uninstalled, open the Microsoft Store.
5. Search for the app by name.
6. Select the app from the search results and tap or click Install to download and reinstall it.

Reinstallation can often correct corrupt app files or properly re-register the app with the system, resolving the ‘x’ issue.

Step 4: Seek Professional Assistance¶

If the previous steps do not lead to a resolution, the problem may be more complex and require expert intervention. At this stage, it is advisable to contact support. Depending on how you obtained your computer, you might first reach out to the original equipment manufacturer (OEM) from whom you purchased the device. OEMs often provide support specific to the hardware and the pre-installed software image.

Alternatively, or if the issue persists after contacting the OEM, reaching out to Microsoft Support is the next step. Microsoft support personnel have access to advanced diagnostic tools and knowledge bases that can help identify and resolve more stubborn issues related to the operating system and its components, including modern app management.

Deeper Dive: The Role of App Packages and System Integrity¶

Modern apps in Windows 8/8.1 and Windows 10 utilize the AppX package format. These packages bundle the application files, manifest (declaring capabilities and dependencies), and other necessary resources. When an app is installed, the system extracts the package contents and registers the app with the operating system. This registration process involves updating system databases and setting up necessary permissions and associations.

Errors during the initial installation or subsequent updates can leave the app in a state where its registration is incomplete or corrupt. The ‘x’ symbol can be interpreted as a visual indicator of this invalid registration or a failure detected by the system’s app management framework. The “This app can’t open” message is a direct consequence of the system’s inability to find the necessary components or valid registration information to launch the app process.

System file corruption, issues with user profiles, or problems with the Windows Store cache could also indirectly contribute to app installation or launch failures. While the troubleshooting steps outlined primarily focus on updates and app reinstallation, ensuring the general health of the operating system is also crucial. Running System File Checker (sfc /scannow) could potentially fix related system file corruption, although this is a more advanced step not specifically detailed in the original resolution but relevant to system integrity.

For individuals or IT professionals involved in creating and deploying custom Windows images, the mention of app injection errors is particularly relevant. Integrating app packages into a Windows image (.wim file) requires careful execution. Any errors during the DISM (Deployment Image Servicing and Management) commands used for package provisioning can lead to apps being marked with the ‘x’ when the image is deployed. Monitoring the output logs of these deployment tools for errors or warnings related to app package installation is a critical step in preventing this issue in large-scale deployments. Ensuring that the base image and the app packages themselves are from verified and uncorrupted sources is paramount.

Illustrative Scenario: User Experience and Troubleshooting Flow¶

Consider a user, let’s call her Sarah, who has a Windows 8.1 laptop. One morning, she notices that her Mail app and Calendar app tiles on the Start screen have the dreaded ‘x’ in the corner. When she clicks the Mail app, she gets the “This app can’t open” message.

• Initial Reaction: Sarah first tries clicking the apps again, hoping it was a temporary glitch. No luck.
• Step 1 - Waiting: She leaves the laptop on for an hour while doing other things, hoping it fixes itself. The ‘x’ remains.
• Step 2 - Windows Update: Recalling that updates fix problems, Sarah goes to PC Settings -> Update and recovery. She checks for updates and finds several important ones available. She downloads and installs them, including a restart. After the restart, she checks the Start screen. The ‘x’ is still there on both Mail and Calendar.
• Step 3 - App Management: Sarah decides to try reinstalling the apps. She right-clicks the Mail tile, selects Uninstall, and confirms. She does the same for Calendar. Then, she opens the Microsoft Store. She searches for “Mail, Calendar, and People” (as they are often bundled). She finds the app package and clicks Install. The apps download and install. Returning to the Start screen, the new Mail and Calendar tiles appear without the ‘x’. She clicks them, and they open successfully.

This scenario illustrates how following the recommended steps can often resolve the issue. It highlights the progression from simple checks to more direct intervention with the affected applications via the Microsoft Store.
