Windows 10: Error 0x800f081f when installing KB4556799

I have had this error for some time, still do

"2020-05 Cumulative Update for Windows 10 Version 1909 for x64-based Systems KB4556799 - Error 0x800f081f"

Have been "contacted" by a Microsoft agent and followed all the steps asked, which came in precomposed template forms with typo's on for command...

"Please try below methods

Method 1: Configure Your Group Policy
It’s possible that your group policy is affecting Windows ability to activate the installation.

Note: Natively, the Group Policy Editor is only available in Windows 10 Pro, Enterprise, and Education. Thankfully, there’s a workaround. You can follow our guide to accessing the Group Policy Editor on Windows 10 Home..."


It continues for pages, which I followed exactly, expect the typo of "ism" instead of "dism" and after making a bootable iso and many hours still the same error occurs. It's been at least another 2 hours since I told him it still doesn't work and there has been no response. Been browsing help pages that go back to 2016...

Is there a fix to this?

Error 0x800F081F

Hi,

I have followed the instructions below until i get to set 2. and it is just jargon to me... what does mount the iso image that's created in step 1?

Is there a simple youtube video i can just follow?

Error code 0x800F0906, 0x800F081F, or 0x800F0907

To fix the error codes for Windows 10, follow these steps:

1. Download the Windows Media Creation tool, and create an ISO image locally, or create an image for the version of Windows that you have installed.
2. Configure the Group Policy as in Method 2, but also follow these steps:
   1. Mount the ISO image that's created in step 1.
   2. Point the "Alternate source file path" to the ISO sources\sxs folder from the ISO.
   3. Run the gpupdate /force command.
   4. Add the .Net framework feature.

Solution for error 0x800f081f for Windows 8.1 or Windows 8

If you receive Windows Update error 0x800f081f, it means that Windows Update cannot determine the cryptographic service provider, or a file that Windows Update requires (named catalog store) is corrupted.
To resolve this problem, follow these steps:
Step 1: Use System File Checker to repair damaged Windows files
Use the System File Checker tool to repair damaged Windows files, and then run Windows Update again. To do this, follow these steps:

• Open an elevated command prompt.
• Run the following command:
  sfc /scannow
• Try to install update again.

For more information about the System File Checker tool, view Use the System File Checker tool to repair missing or corrupted system files.
Step 2: Run the DISM tool
If the problem continues, use the Deployment Image Servicing and Management (DISM) tool to fix Windows corruption errors. To do this, follow these steps:

• Open an elevated command prompt.
• Run the following command: DISM.exe /Online /Cleanup-image /Restorehealth.

Important When you use the /online option, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if Windows Update service is broken, don’t use the /online option. Instead, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
Note Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.
To learn more about this tool, go to Fix Windows corruption errors by using the DISM or System Update Readiness tool.
