I did and upgrade yesterday from 669 to 672 which went very smoothly. Everything is running fine here with one small exception. The license expiration date info has disappeared from the "Protection status" window. I had it briefly yesterday after a second re-boot but today after starting my PC it is gone again. Updates, both manual and automatic work fine, and I have about 14 months left on my 2 years license. Not a big deal really. Just wondering if anyone else is seeing this.
