UPDATE: Here are the supplies needed for this.
1. A Working already Windows 7-10 Computer.
2. Your Chromebook
3. An Internet connection on both devices.
4. A constant battery connection to the Windows computer
5. Sustainable battery life on your Chromebook.
6. At least 50-100 MB of free space on your Windows Computer.
I will not release the rest of this topic until after January 4th.
UPDATE: OK, sorry I kept forgetting to post this. I'll get right into the instructions.
On your Windows 10 computer, visit the site https://remotedesktop.google.com/access
Press the blue "Turn on" button.
Set the name and the pin, and then when a window pops up, press "Yes".
Make sure your computer doesn't shut down or unplug, or else you won't be able to use windows on your Chromebook.
On your Chromebook, visit the same site, "https://remotedesktop.google.com/access"
Under the Remote Devices category, select your computer.
Enter the PIN you set earlier, and check "Remember my PIN on this device".
After some loading, you should see a live display of your computer screen, while being able to control it. You may also want to change some settings (the blue arrow on the right side of the screen), such as shared clipboard and fullscreen. If you would like to map the right control key to the Windows Logo button, then map "ControlRight to MetaLeft".
