Windows 10 Installation Errors: 0xC19001DF and “Something happened”

I’d reserved a free upgrade to Windows 10, and today when I checked the Windows Update history in the Control Panel, I noticed that my “Upgrade to Windows 10 Pro” failed with error code 0xC19001DF - 0x500012.   


So I downloaded and created Windows 10 installation media and tried to install Windows 10 from media, but it failed part way through and returned me to the desktop with the error, “Something happened.  Windows 10 installation has failed.”

You will experience these symptoms if you have just enough free disk space to pass the compatibility check for installing Windows 10, but not enough disk space for the additional updates that are installed during setup.


If you receive these errors on a device that has little free disk space, try freeing up additional space and try again.  Depending on the device, you may need 10-13 GB of free space to install Windows 10.  We’re currently working on modifying the compatibility check so that it doesn’t underestimate the amount of space required.
