The Windows Update Error 0x8007012f on Windows 10 PC can show up whenever we try to install any kind of Windows update (including apps, system and feature updates).

Causes of Windows Update Error 0x8007012f

  • Poor internet connection:

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

  • Presence of malware.
  • 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.

  • 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.

Let us now focus on some of the solutions our Support Engineers employ.


Solutions for Windows Update Error 0x8007012f

For a general troubleshoot, we 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.

First, we scan 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..

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

  • 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.

  • Reset Windows Update Service

Since this error is caused mostly by old download files, we need to reset the Windows Update components and rename the download folder to something else, so as to create a new Windows Update folder.

By renaming the old folder, the computer will no longer recognize it and will instead refer to the fresh folder.

To do this:

  1. Open Command Prompt and run it as an admin.
  2. In the console window, type the following commands:
    net stop bits
    net stop wuauserv
  3. Next, enter the following command to delete the qmgr*.dat files:
    Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat”
  4. Press Enter to execute.
  5. Rename the Software Distribution folder using the following commands:
    Ren %systemroot%\SoftwareDistribution\DataStore *.bak
    Ren %systemroot%\SoftwareDistribution\Download *.bak
    Ren %systemroot%\system32\catroot2 *.bak
  6. Then, reset the BITS service as well as the Windows Update service to their default security descriptor using the commands below:
    sc.exe sdset bits
    sc.exe sdset wuauserv
  7. Next, type in the following command to open the System 32 folder:
    cd /d %windir%\system32
  8. You need to re-register the Windows Update components using these commands:
    regsvr32.exe atl.dll
    regsvr32.exe urlmon.dll
    regsvr32.exe mshtml.dll
    regsvr32.exe shdocvw.dll
    regsvr32.exe browseui.dll
    regsvr32.exe jscript.dll
    regsvr32.exe vbscript.dll
    regsvr32.exe msxml.dll
    regsvr32.exe msxml3.dll
    regsvr32.exe msxml6.dll
    regsvr32.exe actxprxy.dll
    regsvr32.exe softpub.dll
    regsvr32.exe wintrust.dll
    regsvr32.exe dssenh.dll
    regsvr32.exe rsaenh.dll
    regsvr32.exe gpkcsp.dll
    regsvr32.exe sccbase.dll
    regsvr32.exe slbcsp.dll
    regsvr32.exe cryptdlg.dll
    regsvr32.exe oleaut32.dll
    regsvr32.exe ole32.dll
    regsvr32.exe shell32.dll
    regsvr32.exe initpki.dll
    regsvr32.exe wuapi.dll
    regsvr32.exe wuaueng.dll
    regsvr32.exe wuaueng1.dll
    regsvr32.exe wucltui.dll
    regsvr32.exe wups.dll
    regsvr32.exe wups2.dll
    regsvr32.exe wuweb.dll
    regsvr32.exe qmgr.dll
    regsvr32.exe qmgrprxy.dll
    regsvr32.exe wucltux.dll
    regsvr32.exe muweb.dll
    regsvr32.exe wuwebv.dll
  9. Reset Winsock using this line:
    netsh winsock reset
  10. Set the proxy settings as well:
    proxycfg.exe -d
  11. Restart Windows Update using these commands:
    net start bits
    net start wuauserv

Usually, the last option is to do a clean install of Windows 10, unless the given steps do not help. It may mean more work, but it will resolve any Windows Update we might be having.
