Resolve Windows 10 Upgrade Error Code 8007002C-4000D

Most of the Windows 10 upgrades I have done so far have gone quite smoothly. However, I did run into an upgrade issue with a customer the other day. Here is what would happen. I would download Windows 10 and it would begin its upgrade process. After Windows 10 got to about 99% installed the installation would reboot. After the reboot, the screen would go black for a bit and then revert back to the previous operating system, Windows 7. Windows would then display error code 8007002C-4000D.

Windows 10 Upgrade Error

Another technician looked at the problem first so I will list the steps he tried.

Step One: Turned off AntiVirus ( Avast ) , Uninstalled Covenant Eyes (Software)

Step Two: Deleted Items in C:\Windows\SoftwareDistribution\Download

Step Three: Ran Command Prompt wuauclt.exe /updatenow

After the above steps were completed, the computer still returned error code 8007002C-4000D.

I decided to take a look at the issue. I decided to “Google” the issue first to see if anyone else had a fix for this problem. I found this Microsoft forum full of people having this issue. I scanned over the thread and found a general consensus that it seemed to be a software giving us upgrade problems. Here are the steps I tried.

I uninstalled Avast and Covenant Eyes software.

I ran system file checker sfc /scannow . System file checker didn’t find anything amiss.

Next I ran msconfig and went to the startup tab. Under the startup tab I removed all software from starting up.

I began the Windows 10 upgrade. Much to my relief and happiness the Windows 10 upgrade was successful.

Conclusion: From the troubleshooting things I tried, I believe unchecking all software from startup is what fixed this issue. Previously, Windows 10 would almost install but after the reboot the software would try starting up. One of the software items I unchecked must have been giving me my issues.

I hope these troubleshooting tips can help you out. Please leave a comment if you have trouble upgrading your computer to Windows 10 as well.

      If you are running Windows 7 and upgrading to Windows 10 this is the process. Type “Run” in the start menu and select it. Type “msconfig” in the run box and hit enter. Next go to the startup tab and uncheck the programs you don’t want starting up. On Windows 8 or 8.1 open Task Manager and go to the startup tab. Under the startup tab click the program that is starting up and click disable.

    How do you know which program to uncheck? I have the Startup tab open and there are 11 tabs checked, starting with MS Office

    As explained I ran msconfig and went to the startup tab. Under the startup tab I removed all software from starting up. Just to be sure I did a logoff/restart and ran msconfig again and found out my Avast had turned the startup check back on. I than uninstalled Avast and went through the whole procedure again. This time there were no startup issues and I ran the win 10
    install successfully. After 2 plus hours I had win 10. Only problem was that my toshiba media player would not play my dvd and I could find no current update to same. Also the windows media player did not work for me either. Downloaded VLC media player and it worked.

    Lots of luck and many thanks to Techspeeder.

      That doesn’t work for everyone. I am currently using Windows 7 and have tried it twice and double checked that the startup items were “unchecked” and remained unchecked through both failed attempts.

        I am guessing you removed any potential software that would give you problems, like antivirus? Also you wouldn’t happen to have any corrupt Windows profiles?

    Have been getting this error message for several failed attempts to upgrade to Win10. Will try this approach today. My only question is why hasn’t Microsoft responded to the many people who have gotten this error – why has MS left us to figure it out on our own. Thanks TechSpeeder, in advance.

    I had this error and tried all of the online help solutions. In the end it was my banking Rapport software! Uninstalled this and then no issue with Windows installation.
