Windows-7 - 32-bit upgrade to 64-bit -
I have 32-bit Win-7 Home premium.
Is there an UpGrade to Win-7 64-bit Home Premium or PRO -
without starting over and paying the full cost to MicroSoft?
"Branded" versions of Win-7 PRO -
these are sold at a much lower cost then the full system is advertised for.
Question: Is this "branded" Win-7 fully installable and usable
for my custom built desktop?
Any disadvantages in going this route?
