Since installing the subject update my main PC is dragging
I've alway's set my preferences for max. performance i.e "0" for CPU settings. Since this upgrade and who knows what else I did, using windows file explorer has been almost impossible to use while crunching. Click on a drive or folder and the circles spins and waits... to update? It's as if Windows is waiting for an interrupt or something? Shut down Boinc and everything works normal.

What are you using for setting's on the new Boinc?

TIA
