No issues here, after updating my desktop and laptop. Or with the laptops of my wife and son. Yes, it's. Larger than usual update, with several restarts required during the installation. I did make sure everyone had fresh backups (imaged) just in case, as with anything major happening.
I have one friend who has had issues — I had to do a clean install for him, which fixed all the issues. I suspect he didn't allow the process to complete (he's very impatient).
