Yeah, that is what I have been using since day 1. Windows 10 LTSC Enterprise version 1809. It works pretty well, gets updated, and has never added anything in terms of bloatware, so im good. Im not sure for how long does this get you covered before they force you to update to Windows 11. I think it was 10 years, so arround 2028 I'll have to update to whatever is the next best thing that's lightweight and long term supported.
