Fix App Crashes on Windows 10: Top Troubleshooting Steps

If an app keeps closing, freezing, or showing an error on Windows 10, start by restarting the PC and updating the app and Windows; these simple fixes resolve many temporary faults. If the crash continues, check whether it affects one app or several, then work through the steps below from least disruptive to more involved.

First, identify what is crashing

Note the app’s name, what you were doing when it stopped, and whether Windows displayed an error message. Check whether the problem began after an app update, Windows update, driver change, or new peripheral was added. This context helps distinguish a damaged app from a broader system issue.

• One app crashes: Focus first on that app’s updates, settings, permissions, and installation.
• Several unrelated apps crash: Consider Windows updates, low disk space, damaged system files, overheating, or a problem with a shared driver or component.
• Only one file or task triggers the crash: The file, project, or operation may be damaged or unusually demanding, rather than the app itself.

Before making major changes, save work and back up important files. If an error message names a file or component, record it; do not download replacement system files from unofficial sites.

Restart, update, and check basic conditions

1. Restart Windows using Start > Power > Restart. This closes stuck processes and applies some pending changes; shutting down and immediately powering on may not do the same thing when Fast Startup is enabled.
2. Install the app’s available updates using its built-in update option or the source from which it was installed. If it came from Microsoft Store, open Microsoft Store, select See more > Downloads and updates, then choose Get updates if available.
3. Check Windows Update under Start > Settings > Update & Security > Windows Update. Install appropriate offered updates and restart if prompted. Avoid interrupting an update in progress.
4. Make sure the system drive has free space. Windows and apps can behave unpredictably when storage is nearly full. Remove files you recognize or use Storage settings; do not delete unfamiliar folders just to make room.

If the crash began immediately after an update, check the app developer’s support information for a known compatibility issue. Do not assume that removing a Windows update is the first or safest answer: updates can include important fixes, and uninstalling one may create other problems.

Repair or reset the affected app

Windows offers repair and reset options for some installed apps. Open Start > Settings > Apps > Apps & features, select the app, and choose Advanced options if that button appears. Select Repair first. Repair is intended to fix the installation without removing the app’s data, though exact options vary by app.

If repair does not help, Reset may restore the app to its default state and remove its local data or preferences. Check whether the app syncs or backs up its data before resetting. Some traditional desktop programs do not offer these controls; use the program’s own repair option or reinstall it from a trusted source.

For Microsoft Store apps, the Store’s update process and Windows app settings are usually the most direct routes. For a work or school computer, an administrator may manage installation and repair options, so contact them rather than bypassing restrictions.

Check compatibility, permissions, and resources

Right-click the app’s shortcut or executable and select Properties. On the Compatibility tab, Windows may offer Run compatibility troubleshooter. Use it when an older desktop app fails on a newer Windows configuration; change compatibility settings only when there is a clear reason, and undo them if the app becomes less reliable.

For a program that needs elevated access, right-click its shortcut and select Run as administrator as a test. If that changes the result, the issue may involve access to a file or folder. Do not routinely run every app as administrator: elevated access gives a program more control over the PC. Check that the app is allowed to access any files it legitimately needs, and be cautious about changing security settings.

Apps can also fail when the PC is short on memory or busy. Close unused applications, then try again. In Task Manager, opened with Ctrl+Shift+Esc, review the Processes tab for unusually high CPU, memory, or disk use. A high reading is a clue, not proof of a fault; avoid ending processes whose purpose you do not recognize.

Reinstall, then check Windows system files

If the app still crashes, uninstall and reinstall it. First confirm that documents, saved projects, and settings are backed up or synced: uninstalling may remove local data. Use Settings > Apps > Apps & features to uninstall, restart the PC, and reinstall from the app’s official publisher or the Microsoft Store listing. Avoid third-party download sites and bundled installers.

If multiple apps continue to fail, Windows system files may be damaged. Open the Start menu, type Command Prompt, right-click it, and select Run as administrator. Run DISM.exe /Online /Cleanup-image /Restorehealth and let it finish, then run sfc /scannow. These built-in tools check and repair Windows component and system files; they do not repair every app-specific problem. Restart after they complete and note any message reporting that repairs could not be made.

For graphics-intensive apps, check for a compatible graphics driver through Windows Update or the PC or device maker’s support channel. Avoid driver-updater utilities from unfamiliar sources. If crashes started after a driver change, the device maker’s instructions can help you determine whether to update or roll back safely.

Use crash details to narrow the cause

Windows Reliability Monitor can show when applications and Windows components stopped working. Search the Start menu for View reliability history, then select a failure to see available details. Event Viewer, found by searching Start, contains more technical logs, but its entries can be difficult to interpret. A listed faulting module or event is a lead, not necessarily the root cause.

For a repeatable crash, note the time, steps, error text, app version, and whether the same action fails on another file or user account. Share those details with the app’s support channel or your IT administrator. Do not publish logs that may contain personal information without reviewing them first.

Frequently Asked Questions

Why do my apps keep crashing on Windows 10?
Common causes include an app bug, outdated or incompatible software, damaged installation files, low available resources, or a Windows or driver issue. Whether one app or several are affected is a useful first clue.

Will resetting an app delete my files?
It can remove local app data and preferences. The effect varies by app, so check its backup or sync options before selecting Reset. Repair is the less disruptive option to try first when available.

Should I reinstall Windows if an app crashes?
Usually not as an initial fix. Update or repair the app, check storage and compatibility, and reinstall that app first. Consider major Windows recovery steps only after backing up files and establishing that the issue is system-wide.

How can I tell whether Windows or the app is at fault?
If only one app fails, begin with its update, repair, and reinstall options. If several unrelated apps fail, check Windows updates, available resources, drivers, and system files. Neither pattern proves the cause, but it narrows where to investigate.

What if an app crashes only when I open one file?
Try another known-good file in the app, if possible. If that works, the original file may be damaged or incompatible. Make a copy before attempting recovery, and avoid repeatedly saving changes over the only copy.
