Messed up UI

Hello. I’m new to blender, I messed up UI and now struggle to make it as it was originally. I tried to delete blender and then install again, but somehow it remembers everything. Can’t find ‘‘file’’ anywhere also Ctrl+N or Ctrl+U does not work. Thank you!

Ensure you have a ‘Info’ window. If not just change one of the windows to one from the drop down list in the corner
File / Load Factory Settings
Ctrl+U to save as default

Everything I needed. That is great, thank you very much!
