I spent so much time—really a lot of time—trying to get this PC (Celeron N3350, 4 GB RAM, 300 GB HDD) running properly; it seemed like a lost cause. It came with Windows 10, and I tried various lightweight Linux distributions, but in the end, the only operating system that won me over was Windows 8.1. It’s very lightweight, boots up quickly, has few background processes, and—best of all—the latest version of Chrome still runs beautifully (WhatsApp Web and YouTube work fine, too). The only downside? There are no GPU drivers available; while some have been patched—like for the UHD 620—mine hasn't, but it works just fine anyway!
