If so how? When im running installation trying to do an "Upgrade" from inside Windows itself using USB or Media Creation Tool it tells me i cannot do it and to restart and run the installer from USB. (but there is no way of "Upgrading" without data loss) Anyone?
On previous older builds, it was possible to "trick" the system into performing a downgrade by running the setup.exe file located in your sources folder. Of course, there was no guarantee that this would result in a stable system, as whatever settings you would be importing into the older system was designed for the newer OS. I do not know if you can still do this, but if you plan to try, I would backup everything before you do.
