Windows stopped installing any program

It sounds like you are experiencing issues with installing applications and updates on Windows 11, which could be related to network connectivity or settings that are blocking access to the Microsoft Store and other installation methods. Here are some steps you can take to troubleshoot the problem:

1. Check Firewall and Proxy Settings: Ensure that your firewall or any proxy settings are not blocking the required endpoints for the Microsoft Store. You can refer to the documentation on managing connection endpoints to verify this.
2. Verify Microsoft Store Registration: Make sure that the Microsoft Store is registered for your user account. You can do this by running the following PowerShell command:

      Get-AppxPackage *Microsoft.WindowsStore*
   

   If it’s not registered, you may need to re-register it using an elevated PowerShell prompt.
3. Use Windows Package Manager (winget): If you are unable to use the Microsoft Store, consider using the Windows Package Manager (winget) to install applications. You can search for applications using:

      winget search <App name>
   

   And install them with:

      winget install <App name>
   

4. Network Connection: Since you mentioned that your Wi-Fi connection is stable, try resetting your network settings. This can sometimes resolve issues with connectivity that affect app installations.
5. Windows Updates: Make sure that your Windows is up to date, as updates may resolve underlying issues with the operating system.

If these steps do not resolve your issue, you may want to consider seeking further assistance from Microsoft support or checking community forums for similar issues.

Hi Amanda, it sounds like your PC is having trouble with system-level connectivity, which usually points to a broken Windows networking component or a corrupted service after the reinstall. If Microsoft Store and .exe installers can’t connect, it’s often related to the Windows Update service, DNS settings, or firewall blocking connections. First, can you check if other apps like browsers work fine for all sites, or is it only certain ones? Also, try running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth in Command Prompt as admin to repair system files. If that doesn’t help, reset your network settings by going to Settings > Network & Internet > Advanced network settings > Network reset. One more thing: are you using any VPN or third-party antivirus? Those can block installers. Let me know what happens after these steps so we can dig deeper.
