Yes indeed, I have also started to experience this after a recent PD12 update.
This needs to be fixed in a more comprehensive way, really...
Issues are not limited to not being able to type or the ctfmon startup fix. Boots are slow, after sign-in it takes minutes for task bar and start menu to become responsive and even then, they will intermittently 'flash' and become unresponsive again.
None of the posted fixes are useful. I know what I am doing and this is not normal.
