The current download page has a Windows icon that downloads the AMD64 user installer. You don't get an option to select the user or system installer. Interestingly, below the Windows icon there are links to multiple ARM64 installers, including the ARM64 system installer, but you don't want that one.

The link to download the AMD64 system installer file is here: https://go.microsoft.com/fwlink/?linkid=852157. This link is on the VS Code installation & setup page in the 'User setup versus system setup' section: https://code.visualstudio.com/docs/setup/windows.

HTH!
