I used to dual boot linux with windows Vista on an old laptop. I had only installed there the first assassin’s creed and Rome total war. Nothing else, never really connected to internet. After 1 year of not using it a part than few total war sessions, vista was so slow that was unusable. It spontaneously became slow for no reason. I completely removed it, left only linux, and that laptop survived 7 years of intensive use, and was still working 10 years later (just too old).
