its an older version from the downloads, 14393 whereas im at 14905
I've asked someone for help on this, it might be a bit until I get the info, or he get's in touch with you.
yes it is from the university I work at. I am a hardware architect there, and one of the few that are currently running windows 10 at all. I have log in to the volume licensing center and it is an older version then 14905 looking at both education and enterprise versions
and would perfer not to do a fresh installed as I have 2+ tb of apps installed, and another 15tb of media on this system
There's not much we can do.
Please do not take this too badly, the following is just my own personal and subjective, really honest opinion: As a hardware tech, an IT pro, you can blame only yourself. Hard to believe a pro lets this happen.
It is and has been quite a while a known fact that older builds will expire now, Microsoft repeatedly posting the warning in release notes of each new build:
(Screenshot from Announcing Windows 10 Insider Preview Build 14936 for PC and Mobile | Windows Experience Blog )
In your first post you tell us "I have build 14905, and have it set to fast, today was the 1st day in over a month it allowed me to even log in to check that would always get error 0x801901f4.".
You've had a month and a half since release of build 14905 to take care of this issue, for instance if that had happened to me I had immediately after noticing any issues installed Windows 10 Education version 1607 build 14393 on a spare machine, opted in to Fast Ring on that machine and in that way got the latest Insider Fast Ring build upgrade, made an ISO of it and now simply upgraded the problematic machine.
Your 15 TB of media files will not vanish when you start from scratch. Just backup your date before clean installing.
BTW, as far as I know build 14905 is not expired yet? Might be I am wrong, I have to test it, can confirm yes or no in about 20 minutes (installing it now on a Hyper-V vm).
OK, checked, build 14905 is really expired. All expiration dates can be seen here: Windows 10 Insider build expiration dates (thanks Cliff ).

There is a way to upgrade without losing files to latest version but takes a bit of patience. Another user followed this and got back up and running.
Install release version of windows 10 education in a virtual machine (no need to activate it),
Join Insider Programme inside vm.
After a couple of days or so it will download the updates to latest Insider version.
When it asks you to upgrade, search for hidden install.esd file and save elsewhere.
Then convert the install.esd file to an iso using
ESD to ISO - Create Bootable ISO from Windows 10 ESD File - Windows 10 Forums
The from the expiring build, double click on iso and run setup.exe.
Obviously you need to do it before 15/10/16 when it stops altogether.
