There is a LOT of discussion here about the Microsoft Web browser Edge and Windows 10/11. I have some questions. Background: At present I'm a heavy user of Windows 10 Home Edition, Firefox, KEdit, Rexx, etc. From a move, I have a Windows 7 Professional system in a box and am eager to get it running. That system has the 100,000 lines of code for my Web site I'm eager to get on-line. I'm considering plugging together a desktop computer for a Web server, with, say, some 16 core AMD processor, solid state memory for much of the file system, e.g., the SQL part, running some version of Windows Server 2019. (1) Simple question: This thread has many mentions of a widget. What is a widget? Maybe I use them nearly hourly, but I don't know just what they are, what the definition is. (2) My understanding is that with Windows Server, can turn off the automatic updates. Is that true? Hopefully. (3) I am guessing that with Windows Server I can still run software that has long, commonly run on Windows, e.g., KEdit, Firefox, Rexx, some IBM code in Fortran for the classic applied math of linear programming, a Fortran compiler, Adobe's Acrobat PDF reader, Knuth's TeX mathematical word processing software, .... Is this true? (4) I'm guessing that Windows Server will have less of the intrusive, unrequested popups, suggestions, recommendations, etc. about shopping, weather, travel, news, celebrities, etc. than Windows 10/11 have. Is that true? (5) Generally, if I want or need to leave Windows 7 Professional, I hope to move to some version of Windows Server and just stay away from Windows 10/11. Is that doable? Thanks!!
