What triggers Windows Update Error 0x8007012f?

The following factors cause this error;

i. Poor internet connection:
If we have poor internet connection, the download will not be complete and files might get corrupt.

ii. Presence of malware.
iii. Firewall or security:
These security features manage incoming traffic to our computer and they filter what is coming in. If they are overprotective, we might encounter issues when downloading the updates.

iv. Old installer files:
A major reason can be the old installer files present on computer. The update might get interrupted at some point and if we download another copy of the installer files without completely deleting the old files, Windows Update does not recognize the new files. Unless we remove the old downloads first we will get the error.

Now, let us focus on some of the solutions our Support experts applied to fix this issue.

Steps to fix Windows Update Error 0x8007012f?

Generally, to troubleshoot this issue, you need to switch to a different internet connection. If we cannot connect via a cable we move our computer or laptop in the same room as the router/modem.

Start by scanning for malware and get rid of junk files. Not only will this remove nasty elements from computer, it will also be making more space for the download..

Then, you should reboot our computer. Starting with a fresh system helps eliminate temporary glitches that might be getting in the way of the update process.

How to Run the SFC Tool?

The System File Checker is a built-in utility to scan, repair, or restore corrupted system files on Windows 10.
If the Windows 10 error 0x8007012F triggers by corrupt installation files or Windows Update service, running this tool should fix it.
To run this tool, open Command Prompt with administrator privileges, and enter the command:

sfc /scannow

If the SFC tool does not work, we need to run a deeper scan using Deployment Image Servicing and Management or DISM tool. It works just like SFC, just that the scope of the scan is bigger and deeper.
The commands we use for DISM include:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

We let the tool run its course because it will automatically try to repair any corrupted files detected during the scan.
