April 23, 200719 yr I'm a bit confused.... In the title you say one can convert it from Enterprise to Ultimate yet in the post you are talking about Enterprise to Business! Slip? Also, the key you installed it with won't let you transform it (and I'm sure this falls under the incidence of rule #1 of msfn...). Although interesting, I believe you should read the rules before posting. Cheers.
April 23, 200719 yr No, its not strictly violating rules.His method explains how to make vista-setup think its a Business Edition & hence allows you to upgrade to ultimate.
April 27, 200719 yr wow nice, does this keep using the VLM activation key of Enterprise, or do you still need to use up one of your MSDN Ultimate activation keys? (you only get 10 Ultimates per MSDN) if not, what does this really get you in the end? I guess if you have a lot of stuff installed/tweaked it's a time saver. Edited April 27, 200719 yr by JazJon
April 30, 200719 yr This simply allows you to update Vista from one version to another. The keys are locked to the software so you wouldn't be able to use the same key. Just like I thought I would get over by getting the Student version of Vista home premium for $65 then pay the upgrade fee to Ultimate, it doesn't work. It knows I have an academic version and makes me pay the full price to upgrade to Ultimate.
