Upgrading From Vista Ultimate to Seven Pro
Hi all,
I currently have Windows Vista Ultimate installed in my laptop. However, I have just received a free Windows Seven Pro upgrade from my MSDNAA program.
I have seen in another post (Upgrade questions) that to upgrade from Vista Ultimate to Seven Pro, I will need to do clean install. I have also tried Windows Seven Upgrade Advisor and it says the same thing.
The question is, how do I install the Win7 Pro Upgrade in my laptop?
Do I have to format it?
Is there a way to 'force upgrade' it?
Since my laptop was initially installed with Vista Business, is there a way to roll back to that version without losing my settings?
Can a Win7 Pro Upgrade disc be used for a clean install?
And one of the most stupid question is, does the clean install mean that I have to format everything
or
Does it simply mean that the files can be overridden but no settings will be carried over?
If settings are not carried over to my Win7, does that mean I will lose registry entries of all my installed programs?
Thank you in advance, and sorry if these questions were filed already in another post.
