i found the problem with kodi not shutting down when you press exit etc.etc. this sometimes happens along with a 'path' box popping up when browsing for movies in kodi.
the culprit is networking. looks like kodi does not like it when you turn off the LAN card if you have HomeGroup enabled. my solution was to 'barr' internet access which is set a static address and no dns.
i also turned off 'get files from other computers on your network' for windows updates as i domt want anything updating when everything is configured.

i have my responsiveness back in windows. i turned off 'send problems' in the nvidia config. this helped a loooot but then i went one stage further and stopped the config app starting with windows and bam... windows is a loooot faster. if i need the config app then i can always start it from the start menu.

i also applied my 'startup' reg tweaks to start kodi when windows starts.

 Could you be so kind as to expand on the above? What do you mean you "barred" internet access? On what did you apply this? How? Why?

Also, what's the "send problems" in the nvidia config you're mentioning? What's the "config app" you're referring to? Nvidia Experience?
Thanks in advance.
