No ESD files showing in C:\$Windows.~BT\Sources Anything I can do?

You have to snag the Install.esd - before allowing the Reboot...
Just copy the install.esd to another location..

because after the Reboot (upgrade) it is removed..

That's not always the case. My install.esd is still there and I've restarted my computer at least 5 or 6 times.

That's also what I said on Post #6.
My Install.esd for 14257 is still in the Sources folder.

I wonder why it gets deleted on some systems and not on others.

I wonder that too. I have been capturing mine before upgrade restart - maybe I ought to just check if it's necessary - honestly, I've been running extended disk cleanup after upgrade is done and not even checking.

I guess it's another Windows 10 Mystery. "Why am I not getting the latest Preview update? I'm on the Fast Ring" and "Why did my install.esd get deleted?" Only the shadow (MS) knows! :)

Finally figured out what was going wrong and I couldn't mount the ISO image. I had Winrar set to be the default program for ISO images for some weird reason. I uninstalled it and was able to mount the ISO image created by ESD to ISO. Learned something the hard way. :

I did not know that.
Thanks for the info.

The size of my ESD files is the same before restart and after the installation is complete.

I copy the install.esd before the restart because I have had install failures that then did delete the file. I do not like to download the entire update again.

Many programs that use the same file formats will automatically take ownership of a particular type during installation, quite notorious are the graphics editing programs, just have to watch closely during the install. Some will actually prompt with a list of formats [extension] that can be associated, check or uncheck as desired.
