There is probably 10MB worth of driver, and 220MB worth of crapware. If you install a fresh copy of Windows those hardware vendors are going to try their damned hardest to get their crapware back on to your machine.
That 220MB includes some app with a not native UI (likely ugly and unintuitive) to enable unnecessary features.
I have it even worse: every time I plug my Razer mouse into a different port, the driver installer comes up. I've NEVER downloaded the thing, and it came to me through Windows Update. I always say "Never Install" but it always comes back, but the mouse functions fine without.
I have just opened support.lenovo.com and checked for the drivers of Yoga models, randomly chosen 4 of those, and all the official WiFi drivers are worth: 64MB. I am not sure what the author was downloading then.
