I recently updated all my machines to the newest windows 10 1803 insiders preview build. How every my RCA Cambio 2 in 1 Tablet did to and it has totally started having problems because the intel atom and 2gb ram are not compadible to run well. Ive Contacted RCA they say they do not have support for windows 10 and whata worse is it never came with any product key and rca cant give me one. I really need to do a complete clean reinstall of windows 10 Home 32 bit and the drivers from RCA but I will not be able to re activate my product with out the original key. Dose anyone have any suggestions on how i can find or retrieve the original key so I can do a clean install and fix my device?
