IDE on Win 10 - fresh installation needed

Hi

I've been using IDE for several years now. My libraries are curropted and everything works crazy slow.
I've tried uninstalling and re-installing, but my problems continue. When I manage libraries, it updates for several minutes. Also when i compile and upload it takes forever. It didn't used to be like this.
How will I make it all good again?!

Kind regards,
Chris
