I purchased a new laptop which I’ll receive shortly…The operating system is Windows 7 Home edition.

I will want to upgrade (or change OS) to either Professional or Ultimate.

I am faced with the following options:

Option 1) I’ve read about this new Windows Anytime Upgrade which will upgrade your current OS to another version provided you have a Windows Anytime Upgrade Key.

Option 2) Assuming I already have the DVD and license product key for Windows 7 Professional (or Ultimate), simply place the DVD and upgrade while providing the product key.

Option 3) Completely format the laptop assuming I have the appropriate DVD and product key.

My questions are the following:

How is the Windows Anytime Upgrade Key different from the DVD product Key?

Are they the same?

If I decide to go along with option 1), can I use the DVD product Key or do I absolutely need this Windows Anytime Upgrade Key?

Thanks in advance!

This question came from our site for professional and enthusiast programmers.


There are 2 disk product keys:

  • Upgrade Disk

  • Full Install Disk

Since you are already on windows 7, anytime upgrade is ideal to move onto another edition as its faster and doesnt require full program re-install.

Anytime is also cheaper than an upgrade disk.

Upgrade disk is really ment for people upgrading from a previous OS, such as XP or Vista

    I’ve read that the version of Windows cannot be modified after installation. I have read several times that specifically, Home cannot be upgraded to Professional (or Ultimate) without re-installing. Are you sure it can be done? – Synetech Feb 8 '12 at 18:07
  • yes, I'm sure. microsoft.com/windows/buy/… It clearly says upgrade from: 'starter' or 'home', and they even have different prices – Abdul Hfuda Feb 8 '12 at 18:12
  • Cool. I always thought it should be possible (after all, you can upgrade from one whole version of Windows to another; even XP to 7 indirectly through Vista!), so I was surprised when I looked it up a while back and all the responses said it could not be done. Thanks. – Synetech Feb 8 '12 at 18:16
