Win 7 Upgrade Install question

I running Vista home basic 32 bit.

My question is can I do a clean install of Windows 7 home premium using the upgrade version?
I heard that you have to validate your old OS by inserting the vista dvd I have a vista re installation DVD that was provided to me by Dell when I bought this PC.Is this information correct and would the vista dvd I have work? or would it have to be a vista DVD I bought (not from dell).

Yes, you can do a clean install with the upgrade disc assuming your PC is compatible with Windows 7. It probably is if it was built in the last 3 years or so.

You don't have to validate your old OS by inserting a DVD.

So ill assume there is a custom option to format and wipe during the install process.Ok so my other questions are why would anyone have to purchase the full version if they can do a clean install with the upgrade?.I was sure there had to be a way legally for them to validate that you are deemed able to use the upgrade.So is there more to this clean install like some sort of registry tweak? Or is it just the same process like if you did a clean install of vista?(boot into dvd,format,install)

thanks

Most people are able to activate with no issues. A few have issues and can either use a registry tweak or use the old "double install" trick that was so common on Vista. Both of these workarounds are documented on this site. I didn't have to use any workaround and most people don't. You can even install on a brand new drive that has never seen an OS.

Those using an upgrade disc are required by the EULA to have a qualifying copy of an earlier OS. But you aren't asked to insert it or enter the product code.

The install process is essentially like Vista, but more streamlined. You would typically choose "custom install" and then choose "drive options/advanced".

The only people buying a full retail version are people that don't have a qualifying earlier OS or who are uninformed.
