i have been searching around for the use of the windows 10 updates i know that in windows 7 sometimes when you try to install a program it fails and asks for an update to be installed first but as far as i have been using windows 10 without installing updates i didn't face any issues i don't know if my usage is not heavy or i'm just not hitting the spots where updates needed and i really want to know if i didn't install any updates what am i gonna be not able to do also if it differs if it's LTSC or Pro like for LTSC it's security updates or something like that are they all the same also what am i gonna get for downloading updates and staying up to date in windows 10 also in windows 7 if the windows is not updated some sites wont functional (ex: [Note from mod: Don't link warez sites])
You are vulnerable to security breaches, always best to keep your OS uptodate. No difference except for when the non LTSC SKU is out of service but same updates. A secure as possible OS.
