|blaq said he would try to make absolutely sure his system uses just one graphic card,
and then give it a week or two and see if any reactivations are done.
One of my laptop has two graphic cards build into it from the manufacturer. It has both the discrete graphic card and the graphic card built on the motherboard. The switching is done manually on demand or when the power plug is inserted/taken out.
I saw this morning the laptop demanding to be activated again, which is less than 90 days. I purchased Sandboxie about a month ago. So I was surprised it asked for reactivating in such short period. It also gave me the option to be done silently in future, which I checked.
BTW, lots of the new laptops on the market these days have two graphic cards.
