Probably somewhere around the late 2000s or early 2010s, I'd say. By that point, you could already buy a PC with enough power to do almost anything that most people needed. They ran Windows 7, which is arguably still the best version of Windows that Microsoft has produced. Everyone's major important software ran on Windows PCs first and anything else second. Everyone's hardware came with Windows drivers. There has been some useful progress in hardware since that time, particularly in the areas of storage, networking/communications, graphics/displays and lower energy consumption. However, in terms of the fundamental capabilities and "shape" of a PC, things haven't really changed much since that time. More importantly, there has been relatively little real innovation in mainstream PC software for years, it's just that often now you only rent it, it keeps changing itself around, and it tries to spy on you all the time. The interesting innovations in software are almost entirely in either the mobile space or online services today.
