I don't run Windows, but what specifically is slow for you? There are some things which are slow on all platforms like icomplete, doc-view, and very long lines; these are typically replaced by something like Selectrum, pdf-tools, and RIP respectively by users. Startup can also be slow if you have a large config, the way to fix this is to use with-eval-after-load around packages, or the use-package package and to temporary set the following during startup:
(setq file-name-handler-alist nil
gc-cons-threshold most-positive-fixnum)Of course using emacs -q to find actual errors in your configuration could also be useful.
