Most of the methods here don't work anymore except for deleting VUDUStartWizard in /system/apps (if you have TWRP recovery installed for intel base nextbooks). But even with that app removed, your entire system is still restricted. By restricted I mean you can't install apps or modify any system settings within UI. Attempting to install apps via adb results in "Failure, system not activated" etc. It seems they modified a lot of android system apps and integrated their POSA (piece of sh*t activation).

BUT, since intel based tablets such as my Nextbook Ares 8a can have recovery and rest of system flashed, it is indeed possible to flash a stock android or even a windows OS. I have very little knowledge of building a ROM myself. If someone could figure out a way to maybe replace all the modified system files back to stock unless someone here has a better solution...
