Downloading the Bitcoin Core client software from bitcoin.org seems a bit challenging and seems like it requires to understand how to use command line functions, which I don't have a good handle on.
You *absolutely don't* need any command line, or other typical-tech-savy-knowledge, to run bitcoin-core.Here is for example an overview of the GUI.
In your case, i would recommend downloading the graphical (`bitcoin-qt`) client and set up pruning.
The full validation is going to take some time and the GUI will hang during that time, once initial sync has been processed
it'll be much faster to get up to date with the network when you start your bitcoin client.
You can find binaries at:
- The official project webpage: https://bitcoincore.org/en/download/
- The website (bitcoin.org) you just visited: https://bitcoin.org/en/download
