Will Win 10 TP Final Update be a full OS?

Question

Freeware

If I install the free, free Windows 10 Technical Preview, which also has free upgrades, and stay on it after the official closure of the Technical Preview and the announcement and release of Windows 10, will I have a perfectly working system?
I dare to assume that the final update for Windows 10 Technical Preview, which will be released, will already be similar to the full-fledged Windows 10, i.e. without bugs inherent in TP, flaws and software incompatibilities (in the case of OS X Golden Master, this is exactly the case).
PS I do not need Windows for everyday work, since I am an OS X user. I only need it to run programs developed for Win + games.

Answer 1

It is not free and free, and on April 15, 2015 it will become a "pumpkin"

Well, until then there should be no problems with updates

Answer 2

Yes, you can reinstall if anything, and that's all.
