Hi @SRApublic1 - Yes, you can move all your Origin games from one Windows computer to another, no problem. As long as it's registered in Origin, the games follow your Origin account. You don't need to uninstall from the old laptop, but you should log out of your account on the old laptop before you log in on the new one.
To Move your games from one computer to another:
On your new laptop, download and install Origin from the Origin download page: https://www.origin.com/store/download Log in to the same account you were using on the old laptop, and all of your games will show up in My Library. You'll need to download and install SimCity from this page. Here are some tips on that: https://help.ea.com/en/help/origin/origin/download-and-play-your-games-in-origin/
To Move your existing Regions/Cities:
For Multiplayer / online mode - your games are all saved online. If you're not seeing them, you probably just need to change to the correct server. For some reason, SimCity doesn't automatically open to the server you were on when you switch computers. (it WILL open to the server you were on last on the same computer; it doesn't save that info in Origin) How to Choose a SimCity Server
For Single Player / offline mode - your games are saved on the hard drive, not online. You will need to copy the files in the game folder from the first computer, and transfer them to the new computer. Use a portable storage device like a thumb drive or external hard drive. On the original computer, copy all the files and folders from the Games folder - default location is <YourWindowsUserName>\Documents\SimCity\Games. Move all the files on the portable drive to the Games folder on the new computer. (Make sure you don't accidentally end up with nested Games folders - just move the files.)
A couple tips:
If you have any issues, don't hesitate to ask.
Happy Building!
