Hello,

 

Error 0x800f0845 indicates corruption with update/system files.

 

Suggest you to run System File Checker scan:

 

  1. Search for 'command prompt' using Windows Search.

 

  1. From results, right click on Command Prompt and select Run as administrator.

 

  1. Type sfc /scannow command and press Enter key.

 

  1. Let the command complete and then reboot the machine.

 

If that doesn't works, try these steps:

 

  1. Search for 'windows powershell' using Windows Search.

 

  1. From results, choose Windows PowerShell and select Run as administrator.

 

  1. Then type/paste following and press Enter key:

 

Repair-WindowsImage -Online -RestoreHealth

 

  1. Let the command complete, restart your system then.

 

Let us know if this helps!
