Bottles

Bottles is for the one Windows program you cannot replace. It runs Windows software on Linux through Wine, a compatibility layer that translates Windows instructions rather than emulating a whole PC.

Each program lives in its own "bottle", a self-contained Windows-like folder with its own settings. That separation is the main advantage over older tools, because a program that needs an odd tweak gets it without affecting anything else you installed.

It replaces nothing from Windows and adds no software of its own. Treat it as a safety net. Old accounting software, a niche label printer tool or a game that never came to Linux are its natural jobs. Anything that needs deep hardware access or a strict anti-cheat system is still out of reach, and there is no guarantee any particular program will work.
