Anytime upgrade

Can I use Home Premium to Ultimate upgrade key to upgrade Professional to Ultimate?

I know it seems like a waste but that's the only option for me.

Is it an Anytime key or a retail Upgrade key?

If it's Anytime, you can try it to see if it works. Start Process by typing Anytime in Start Search box.

If it's retail, then you can try inserting key into Anytime and if it fails, clean install using installer. There is even a workaround to change between Win7 versions - let me know if u need it.

What is the difference? Windows 7 Ultimate Anytime Upgrade. That's what is written on it. I don't have it yet so I can't try. I'd like to know before I aquire it. That's why i'm asking. Thank you for your help.

When you buy a windows anytime upgrade all you get is the product code, there is no install media included. With anytime upgrade you just launch the app in windows, type in your code, and it unlocks the features of the version the key is for. You don't even have to insert a windows DVD for it to work all the files are already on the PC. If you were to do a clean install I don't know if the anytime upgrade key would work. What I mean is, you might have to install your current version and then do the anytime upgrade after you log into windows.

When you buy OEM or retail you get the install media. With retail you should get a 32 and a 64 bit DVD, with OEM you'll get one or the other but not both. Full OEM and retail codes are good for a clean install, don't know if they work for anytime upgrade, my guess is yes but I don't know for sure.

As far as price goes i would expect anytime upgrade to be the cheapest followed by OEM then retail.

yes I thought is goesd like that. My only question is: Does Home Premium to Ultimate Anytime Upgrade works with Professional?

Um, I don't know for sure but, I would think yes. You may have to do some Googleing or even contact Microsoft to nail it down one way or the other. I would think if you had Home Premium or better yes, Home Basic or lower no.

Ok. Tnx for your opinion.
