the old motherboard. You would have to call Microsoft and convince them.
I purchased Win 7 professional OEM and Office 2010 full version retail.
I am currently running Win XP pro SP3 and MS OFFICE Pro 2000. My machine runs pretty good but I want to upgrade the system down the road.
I assume that my system will run the same by installing Win 7 and Office 2010, perhaps better. Can I replace the motherboard and processor etc down the road without activation or licensing issues?
