Hi JANA AKASH
If WhatsApp and other apps appear installed but will not open, and some downloads never complete, the issue may be with Microsoft Store or Windows app registration rather than the apps themselves.
Please try:
- Press Windows + R, type
wsreset.exe, and press Enter. Wait for Microsoft Store to reopen. - Go to Settings > Apps > Apps & features, select the affected app, then choose Advanced options > Repair. If that does not help, try Reset.
- Open Microsoft Store > Library > Get updates and install all available Store updates.
- Run the Windows Store Apps troubleshooter and install any pending Windows updates.
- If multiple apps are affected, open an elevated Command Prompt and run:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
If the problem continues, please provide:
- Your Windows 10 version (Settings > System > About)
- Whether WhatsApp was installed from Microsoft Store or Chrome
- Any error message when the app fails to open.
Hope this helps.
