Today I stumbled upon the following 0x8007007e error while trying to update to Windows 10 1903.
Something went wrong. You can contact Microsoft for help with this error. Here is the error code 0x8007007e
To fix this issue for the update process of Windows 10, I needed to clear my WindowsUpdate folder. It’s recommended to let Windows do it for you (method 1), but you may also do it manually (method 2).
Method 1: Run the Windows Update troubleshooter to fix 0x8007007e
Type Troubleshoot in the search bar -> Click Troubleshoot Settings -> Scroll down and click Windows Update (Resolve problems that prevent you from updating Windows).
Follow the steps in the wizard and click Finish. Try to run the update again
Method 2: Clean up corrupted Windows Update folder yourself
When Method 1 didn’t work for you, you may want to manually clean up the WindowsUpdate folder.
Open a command prompt as an administrator and run the commands below. (Tip: copy-paste them in your Command Prompt with a right-mouse click :) )
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserve
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
You should be able to update Windows 10 now. But in case you still face the same error, leave a comment and I’ll try to assist you :)
