We block apps that could damage your PC or cause you to lose data. This sometimes includes apps that worked with a previous version of Windows. If an app won't open after you updated to Windows 10, it probably isn't compatible.
We recommend checking for a new or updated version of the app online. See Overview of device and driver installation for more information. If you don't find a newer version, you can:
- Use the Program Compatibility Troubleshooter to make older programs compatible.
- Install new drivers.
- Uninstall and reinstall an app that isn't working.
- If you got the app from the Microsoft Store, find it in the Start menu, right-click it, then select Uninstall. Then install the app again.
- If you didn't get the app in the Microsoft store, select the Start button, select Settings > Apps, then, if it's available, select Uninstall for the app that isn't working (some apps can't be uninstalled). Then install the app again.
Note
If you can't install your usual antivirus app right away, don't worry. We've included an antivirus solution with Windows 10 at no extra cost. See Stay protected with Windows Security.
