Intel DP55WB mobo with Intel i5 750 CPU.
I tried to upgrade from Vista Hme Premium to Win 7 Pro using Win 7 Pro Upgrade disc; received an error msg saying that upgrade procedure was not allowed !!
I fell back to upgrading using a Win 7 Hme Premium disc.
Because the Win 7 Pro upgrade disc cost more than the Win 7 Hme Prem upgrade disc, I do not understand MS's refusal to allow this upgrade to a more costly product.
I know I may pay an additional fee to upgrade from Win 7 Hme Prem to Win 7 Pro;
and/or use the Win 7 Pro upgrade disc to achieve the same step-up, but that burns two Win 7 upgrade Keys to upgrade one machine !!
Am I missing something? If someone can, will you please explain the Why of this.
Also, are there alternatives?
