Activation problems After Creators fall Update

I have a dual boot home built system with current parts, which has two separate bootable SSD disks, each containing separate retail copies copies if Windows 10 (one Pro x64 and the other home x386). The reason for the two copies of windows is that the 32 bit allows for older programs to still work.This has worked flawlessly ( both showing activtion) with all windows 10 updates to this point. Updating both to the fall creators update went well, with one major exception, namely the pro version activated, but not the home version. The home version says “were unable reach windows activtion servers”. Using the activation troubleshooter give the message that “we found Pro digital license for this device” . It appears that the creators fall update links to only one windows registered and formally activated copy of windows so only one one version of windows can be activated. This seems to be a monumental change, since previously MS was primarily interested in pirates not installing a single windows copy on multiple computers and activtion. This change seems unfair to those of us have full retail copies and should not need a new computer for each version.

Thanks alphanumberic for the suggestion. The followi ng error message resulted.
error 0x803F001 on a computer running microsoft windows no-core editiion. Do not know what this means, but I think something was changed by MS, since it worked for every other upgrade to date for my two copies of of windows 10.

It could be just the volume of activations if you think of millions of pc getting the update it may overload the system

Tried many times to activate with no luck. When I go the activation troubleshooter I get the following message.
" We cannot activate windows on this device as the previous version of windows was not activated prior to upgrading
to windows 10". Go the store to buy genuine windows (0x803f001)". I can absolutely guarantee that the both instances were activated before the most recent update. It seems that MS has decided with this update that the activation process now only associates one instance of Windows 10 with the device (my dual boot compute) even though previously both retail installations were judged to be genuine and were activated on the same computer (no hardware changes). I tried to reinstall the the version that said it could not be avctivated with the same negative result.
Very frustrating
