Where can I find the key for reset windows I can’t get inside

 I tried going on RESET and just keep coming back to this blue screen, it asks me for the windows key, but I can’t get inside the computer because it doesn’t get out of this blue screen, where can I find this key ?

You didn't bother to tell us which model All-in-One you have and if yours came with win8x or Win10 preloaded, then the key is embedded into the UEFI firmware of the motherboard and it will not be printed on any sticker.

You would be able to retrieve that key but it will involve some work on your part as you will need access to a second working PC in order to create boot media.

Macrium Reflect is a free tool that can be used to image and restore PCs, but it also has an option to create Rescue Media (in disk or USB form) that can then be used to bot and/or Repair your PC.

It is available from here: http://www.macrium.com/reflectfree.aspx

What I recommend is the following:
a) Download and install Macrium Reflect (MR)
b) Use the option to create a boot USB stick or CD
c) Download this utility and copy it to the boot media: https://www.tenforums.com/software-apps/2577-showkeyplus.html
d) Boot your PC from the MR media -- it will take a while, so be patient!
e) Once the PC is running, launch that utility to retrieve the Windows product key
