If an app freezes or shows Not Responding on Windows, the problem is usually caused by low memory, a stuck process, a bad driver, or a heavy background task. These fixes help you close the app safely and reduce the chances of it happening again.
Apps commonly freeze because of high CPU or memory usage, a slow disk, a damaged update, a graphics driver problem, or a background process blocking the app.
If the app is handling a large document, export, or sync task, give it a moment. If there is any chance to save, do that first.
Open Task Manager, select the app, and choose End task. This is the quickest way to close a frozen program on Windows.
Launch the app again after a short pause. If it freezes immediately, the problem is likely in the app data, not a one-time glitch.
A reboot clears stuck services, memory pressure, and hidden background issues that can make apps freeze repeatedly.
Install app updates and pending Windows updates. Bug fixes and compatibility updates often solve Not Responding problems.
Free up disk space and close memory-heavy apps. Low free space or RAM can make even normal programs hang.
Outdated drivers can cause freezes, especially in apps with heavy rendering or video playback.
Disable startup apps and background services temporarily to see whether another program is causing the freeze.
Run Windows built-in repair tools if multiple apps are freezing. Corrupted system files can affect several programs at once.
Test briefly with your antivirus or security suite paused if you suspect it is blocking the app. Re-enable protection right after testing.
Apps usually freeze because they are using too much memory, waiting on a slow disk, hit a bad driver, or are blocked by a background process.
Open Task Manager, select the app, and choose End task. If needed, use the Windows command line taskkill command to terminate it.
Yes. Windows updates often include bug fixes and driver improvements that can resolve app freezing issues.
Only as a temporary test. Security software can slow or block apps, but you should re-enable protection after troubleshooting.
Try the same service on a different device or network. If it works elsewhere, the issue is local to your device or network. If it fails everywhere, the service itself may be down - check Downdetector or the service's official status page to confirm.
Yes. A full restart (not just closing the app) clears stale connections, frees memory, and resolves the majority of intermittent glitches. Try this before deeper troubleshooting steps.
Open the App Store (iPhone) or Google Play Store (Android) and search for the app - if an Update button appears, tap it. On desktop apps, look for an About or Check for Updates option in the menu. Outdated apps often break after server-side updates.
If clearing the cache, updating, and restarting have all failed, reinstall the app as a last resort. A clean reinstall removes corrupted data, settings, and permissions that the standard fix steps cannot reach. Your account and saved data are stored in the cloud, so you won't lose anything by reinstalling.
