Computer updated and now Roon is blocked

Uninstall it, and then look under program files and under your documents.  Delete everything you find.

I would also try using a program called CCleaner, to wipe out any previous programs. 

If Windows upgraded, then there should be a restore point that you could revert the PC back to a point where Roon worked.

FWIW, I haven't had any issue with MS updates and Roon. I would look at the Windows firewall settings. Roon should be listed and you can see if it is allowed or not.

thanks, I'll try everybody's suggestions and let you guys know if I can get it working

Is the laptop with the issues your Roon Core?

@gdnrbob I use CC or crap cleaner regularly. The free version is really all you need.
