I bought a computer with Home Premium on it. Can I upgrade to Vista Business? Carol
Hi csteele! According to this web page from Microsoft, yes you can. The second bullet reads:
MicrosoftDoes the edition of Windows Vista currently installed on your computer allow you to perform an upgrade to the edition of Windows Vista that you purchased? If you're not sure, see "What installation choices are available to you?" later in this topic.
So scroll down the page to "What installation choices are available to you?" and click on the question. It will list your version of Vista and the available upgrades. According to the web page, Vista Home Premium has a valid upgrade to Vitsa Business.
