Upgrading Windows 7

my computer is running on Windows 7 Home Premium and i was wondering if I could use a Windows 7 Professional full version to do an upgrade? would i need to do a clean install or simply an upgrade?

Hello asdsker90,

1) You can do either an upgrade or a clean install. A clean install will wipe out your installed apps as well as any data that you have stored on the system partition. An upgrade will preserve all these. So an upgrade is less work. But generally speaking, a clean install is more advisable since you are less likely to have problems in the future.

2) Why do you want to switch editions. Heres a page that compared editions.

Which one is right for you? - Microsoft Windows

You can install any program in XP compatibility mode with any version of Windows 7. Are you referring to Virtual XP?

Unfortunately, MS requires using Anytime Upgrade to in-place upgrade within Windows 7 versions. You would need to clean install.

There is a workaround to fool Home Premium into thinking it is Pro which allows an in-place Upgrade since this is allowed within same version to do a Repair Install. You need to adapt the registry fix here: Upgrade the Windows 7 RC to any retail version Icrontic Tech

AFAIK, Windows 7 Professional retail full version can do Anytime upgrades.

Good idea. You could try inserting your Pro retail key into Anytime Upgrade. Seems like some others have reported doing that successfully. Would you let us know if it works so we can pass it along to others?

If not you'll need to clean install or try the workaround.

It is very important that the Edition ID and Product Name read precisely as shown in tutorial so that the when the installer checks version it sees it's own version and allows in-place Upgrade to continue as a same-version Repair Install always can:

About a dozen times this has worked here using almost all version combinations within Windows 7, however it can fail if not done correctly.

Let us know how it goes, and how performance holds up. Clean installs are always best so that should be the ultimate goal when you can get around to it.

Did you get the message "this is not a valid upgrade key" or something like that? Try retyping the key, it might have got typed in wrong. Also, is your current install activated?

In any case, if you can fool the system, go ahead with that. But theres no reason why a full price key will not upgrade.

The Anytime Upgrade key is different than the Windows 7 retail Product Key.

You buy the Anytime Key online and insert it into Anytime prompt in All Programs to unlock hidden features of the greater version.

Get Windows Vista: Windows Anytime Upgrade

Do you have experience inserting retail key into Anytime, Bill? I do believe I have read it has been done by one of the Gurus here, but I may have it wrong.
