How to Fix Notifications Not Working on Windows

What Causes This?

Windows notifications can stop working when system notification settings are turned off, Focus Assist is blocking alerts, or the app responsible for sending notifications has been disabled. It can also happen if the Windows notification cache gets corrupted, background apps are restricted, or File Explorer and related Windows processes are not responding properly. In some cases, outdated system files or minor performance issues can delay or suppress alerts entirely.

Common Symptoms

• No banner notifications appear for emails, apps, or system alerts
• Notifications are missing from the Notification Center
• Only some apps send notifications while others stay silent
• Sounds play, but no notification pop-up appears
• Notifications worked before and suddenly stopped after an update or cleanup

How to Fix It Manually

1. Make sure notifications are enabled in Windows

   1. Press Windows + I to open Settings.
   2. Go to System > Notifications.
   3. Turn on Notifications.
   4. Make sure options like Show notification banners and Show notifications in notification center are enabled.
   5. Scroll down and confirm the specific app you need is allowed to send notifications.

2. Turn off Focus Assist / Do Not Disturb

   1. In Settings, go to System > Notifications.
   2. Check whether Do not disturb is turned on and switch it Off.
   3. If you use automatic rules, open the related settings and temporarily disable them to test.
   4. You can also press Windows + A to open Quick Settings and turn off Do not disturb there.

3. Check background app permissions

   1. Open Settings and go to Apps > Installed apps.
   2. Find the app that is not sending notifications.
   3. Click the three dots next to it, then choose Advanced options if available.
   4. Under Background apps permissions, set it to Power optimized or Always.
   5. If the app has a Repair or Reset option, try Repair first.

4. Restart Windows Explorer

   1. Press Ctrl + Shift + Esc to open Task Manager.
   2. In the Processes tab, find Windows Explorer.
   3. Right-click it and choose Restart.
   4. This refreshes parts of the Windows interface that handle taskbar and notification behavior.

5. Clear the notification cache

   1. Press Windows + R, type %localappdata%\Microsoft\Windows, and press Enter.
   2. Find the folder named Notifications.
   3. Restart your PC in Safe Mode or sign out first if Windows will not let you modify the folder.
   4. Rename the folder to Notifications.old.
   5. Restart Windows normally. A fresh notification cache will be created automatically.

6. Run system repair commands

   1. Click Start, type cmd.
   2. Right-click Command Prompt and choose Run as administrator.
   3. Run this command: sfc /scannow
   4. After it finishes, run: DISM /Online /Cleanup-Image /RestoreHealth
