Carlos,
? I upgraded my Lenovo laptop, which ran 64-bit Windows 10, to Windows 11 64-bit, without having to reinstall anything...including D-Rats. It was a different story over a month ago, when I had to reinstall Windows 10 and rebuild the registry. So far, I haven't had any problems with D-Rats under Windows 11.
