Voted W10
I did install W11 on some computers but found it has too many basic shortcomings, broken things that worked perfectly on W10, so now I will reinstall back to W10
Mind you I even use customized W11 (done by a group of pple that know what they are doing) that already does away with the dumb new features and which fixes some broken things but I keep finding new missing or not working or broken features that W10 had and mentally I have already thrown the towel in on W11
Expect it to be a historical repeat of W8
Even W10 latest editions have already started the trend to dumbing it down in preparation for totally dumb W11 and so I will go back to W10 2016 edition that I have been using long time and that proved just perfect for a serious work a day machine.
I have TinyXP & Beast edition somewhere on old disks but lately I noticed some more recent edition of it but all links I could find were dead. I think some closed group is holding it for themselves, probably always were and what got to public were leaked files.
