This computer, with 16GB RAM+512GB M.2 SSD is an outstanding value. It runs Windows 11 Pro, which is pre-installed, perfectly. Responsiveness is what you would expect out of a larger system with higher specs. Websites load almost instantaneously, and most applications such as word processing, Libre Office, and so on work fine.I am using this computer as a Plex Media Server, connected to an external USB hard drive with all my movies and media on it. It works perfectly. I can stream videos at full resolution to my Roku TV, and web browsers on other computers in my house. No glitches, no dropped frames, no problems of any sort.They give you an excellent piece of advice when setting it up. That is to pretend you do not have an internet connection. This will install Windows 11 Pro with a local account, and prevent it from downloading tedious updates during the setup process, which could take hours. Using a local account instead of signing up for a Microsoft account is definitely the way to go.
