Chosen Solution

I want to reset my tablet back to the way it was when I first bought it, without all the other extra apps I installed.

You can power off the tablet by holding the power button. Then press and hold the volume UP button and the power button simultaneously. This will bring you to a menu called “Android System Recovery .” Scroll to the option “wipe data/factory reset” using the volume buttons and select it using the power button. This should work.
