A List Of Possibilities

Windows Update Components

All in all, Windows Update components play a key role in the download and installation of updates. If the components go missing, get damaged, or become corrupted, the integration of  Windows updates would go haywire. Hence, if you see “Failed to internally open package. [HRESULT = 0x800f0805 – CBS_E_INVALID_PACKAGE]” in  the CBS log, give Windows Update components some thought. 

System Files

System files influence a wide range of processes of the operating system including update. That means if the system files run into problems, the update process would go haywire. Because of that, you should take system files into account while troubleshooting updates troubles. 

What Are Windows Update Types?

On Windows 10, Microsoft offers two types of updates i.e. feature updates and quality updates. 

  • Quality updates commonly known as Cumulative updates are the mandatory updates that are automatically downloaded and installed almost every month. These types of updates are for maintenance purposes and are meant to fix bugs, errors, and patch security vulnerabilities.
  • Feature updates include new features, visual improvements, and significant enhancements to improve the overall experience and security. Features updates are similarly bigger in size which means they take a longer time to install than the quality updates.

Does The Windows Update Service Influence Windows Updates?

Windows Update service contributes to the success of the integration of Windows updates. Hence, if you have a hard time updating Windows, you should check out the status of the service. 

  • Step 1: Press the Windows key + R to open Run.
  • Step 2: Type services.msc then hit Enter to open Windows Services.
  • Step 3: Double-click Windows Update then go to the General tab.
  • Step 4: Ensure that the Service status is Running and the Startup type is set to Automatic or Automatic(Delayed).


  • Set Windows to automatically download the updates.
  • If you use a laptop, connect it to a power source during update. 
  • Do not turn off your computer while installing updates.
