On Linux you aren't just limited to a specific set of utilities, or a specific UI or Desktop. You can mix and match software to varying degrees. A desktop environment like MATE or XFCE comes to mind for something that resembles a Windows 9x-XP era desktop. Cinnamon and KDE Plasma are similar to Windows Vista-7. GNOME is like current macOS. All of them vary in terms of customization and theming. Most distros have all of these (and more) available in their software repositories and some distros offer multiple ISOs with different software and desktops pre-bundled. For example the Debian installer lets you pick which Desktop(s) you want and then downloads and installs all the required packages. But Linux Mint has 3 different editions each with a different Desktop environment (MATE, XFCE, Cinnamon).
