Thanks, and BTW, I have system images of my Windows 7 with 3 different imaging programs. So, whatever happens, I'll be OK.
I'm going to go ahead and move this directory off to another partition, and if nothing breaks with the next build upgrade, eventually delete it.
At 9841 the file DONOTREPLACE.txt said this
but it did not update the drivers or wim - they remained the same as the initial install so it seems to workCode:Upgrade will not replace the on-disk recovery image if this file is present. Do not delete or modify this file. Build ID: 9860.0.amd64fre.fbl_release.141008-2044
After 9860 is installed, the directory contains:

Since you can't install Build 9860 directly, they are just leaving it so 9841 is the result of a Reset. Probably part of the exercise in upgrading an OS in stages over a long period.
Since that Reset would be like a factory Reset to Windows 10 - 9841, I suppose if you had upgraded over 8.1 or 7, all that information would be lost. Maybe something to test if they don't get the Nvidia stuff straightened out!!
I upgraded 8.1.1 Pro X64 to Win 10 TP then to build 9860. Results are as I listed for the C:\RecoveryImage directory.
I believe the install.wim is from build 9841, the initial Windows 10 TP release. It will stay there as a way to refresh (I think) back to build 9841 when future updates are installed. I believe this is to address the broken refresh in Windows 8 and 8.1 but that's just a guess.
So if you have install.wim it's for build 9841.
If you have install.esd it's for build 9860.
The Windows Update one is showing the .esd file instead of the .wim file and dated Oct 22.
The PC Settings upgrade is still showing the original .wim file.
Since I do not know how to get info on an .esd file, even though it has a newer date, the properties show OCT. 9. So, is the .esd a image of 9860 or 9841, and if you believe they are different, why do you believe that?
I would think Microsoft would want to keep any Reset computers running the same version of Windows 10 so it could be upgraded the same way.
