Where to find & how to upgrade Vista to Win 7

[beanodino1]

Never seems to get any easier on how to update or upgrade Windows,but I'm coming up short on where to find the exact location of the vista to Win. 7 upgrade download or other methods how to ? I used the Microsoft Advisor 7 which says my two Vista are ready to be upgraded to WIN.7 ,but even after re-searching through Microsoft downloads,store, my Vista anytime upgrades I find no clear solution where or how to find the right version then upgrade ! Similar to putting a jigsaw puzzled together & not knowing there are 3 pieces missing. I have two Vista's that both are ready to get upgraded as I am too for my1st time to upgrade to Win.7 like many other Windows owners out there

Microsoft don't offer free upgrades from Vista to 7, you would have to purchase a copy of 7.  Not sure if 7 is still being sold, if not you may need to consider buying a copy of 10.

Not surprised as I thought I search well enough to find this some where else. Each time I would go to Microsoft I saw nothing but Win.10 for purchase most any other directions I took. I seen several ways to configure adding upgrades, but most all seem to complex or needing to download promise programs to get you there. I have seen a true Microsoft avalible vista to Win7 upgrade Image (ISO)files, but not for sure that format would be a risk factor somehow to use instead ? Taking risky chances could just make things worse maybe
