Windows 7: Does 7 upgrade overwrite/remove Vista

Does 7 upgrade overwrite/remove Vista

I just want to make sure that installing 7 as an upgrade 'over' Vista removes all of Vista's operating system, particularly the registry. Is this a correct assumption? I've got some registry entries for magicjack that I can't remove with Regedit due to permission problems and since my "7 upgrade" is due in a few days I don't want to mess with trying to remove them again.

An upgrade will not remove all of Vista. It is exactly that an "overwrite". The over write may make some changes, but you still have Vista. If you have an old car and paint it, tune it up and change all old parts. Looks like a new car, but you still have the old one.

A clean install will get rid of Vista. You can do a clean install with a upgrade disk. Do a custom install, don't activate and then do an upgrade and then activate. You now should be rid of Vista.

I don't think you have to reinstall to get rid of Vista. It should be gone after only one install.

You can get a clean install by formatting and installing. You don't want to do this in any form if you have an upgrade DVD. When I say any form, I mean do not use the Disk Options during the install to repartition or format.
Do you mind further explaining your reasoning here??

If you mean why I say do not format, since having a prior OS installed is a requirement for using an upgrade DVD, why would I wipe that out?

Unless you absolutely must do a clean install of 7 please note a upgrade from vista to Windows 7 is no real ground breaking change, thus no real issues will be seen in the upgrade option, it took about an hour and and half to upgrade my old Vista Ultimate 64Bit to 7 Ultimate and all my programs are running perfectly without a single issue, something older versions of windows always seemed to have, I just did not want to reinstall all my programs and I really don't see the need, thus far the upgrade option has worked perfectly...

Upgrade disks will allow you to:

From the XP/Vista/RC desktop:

1) do an in-place Upgrade (reinstalls all of your programs, files and settings),
2) do a Custom overwrite of the XP/Vista/RC which places all of your files in windows.old and replaces everything else
3) do a Custom install to a another partition or HDD. Another HDD will then be dual-boot unless you unplug the XP/Vista drive, switch cables or change it to boot in BIOS, mark it active, and run Startup repair.

From boot:

1) do a formatted clean install using Custom>Advanced tools which can delete existing partitions, then create new partitions to format and install.

Many report their key being accepted upfront, others have had their key rejected upfront but continued install and were able to activate from Computer>Properties activation link afterward. A few have also then had to do an Upgrade over the installation from the new desktop (aka "Repair Install") which allowed them to put in the key upfront or afterward. If all fails there is a registry fix here.
