Quote from Scataphagos:
Edit....
Oops... read more of the narrative. It IS identified as "OEM"
So, "no" on the mobo changeout... that is IF it's enforced... which has always been a question in my mind. (Does MSFT really catch this, or no?)
The automated activation system usually denies multiple installations. Workaround is the phone activation system.
I have never been denied a re-activation using the phone system and have loaded multiple systems off one OEM license in the past XP/Vista/Win7 numerous times.
Key statements:
"only installed on one system" <- they just have to hear this
plus any form of the following:
"Hardware failure, needed to replace HDD"
"upgraded to SSD"
"Darn OS crashed again, needed to re-format"
"I reformat regularly to optimize performance"
