So I recently bought a new laptop with windows 7 home premium and I wanna upgrade it to professional. I just wanna know, will all the programs I had be uninstalled and the computer would be a fresh kind of formatted or will everything stay as it and only the features for professional be added?
Also I would like to know, would this upgrade void my warranty? (laptop is Alienware M15x)

If you are upgrading the the 32bit version to the 32 bit version or 64 bit version to 64 bit version the answer it no you do not have to re-install the operating system. Do it as a anytime upgrade, you can do it from within your operating system by search for anytime upgrade.
Maybe they need XP mode or domain membership or network backup functionality. I wouldn't call those differences nill if you need/want them. If one needs/wants bitlocker and/or multiple languages across user profiles, then they'd go with Ultimate.
The reason I mention this is because I'm getting ready to purchase a laptop with Home Premium and am deciding whether to go with the anytime pro or ultimate upgrade. I could use the features in Pro and would like Bitlocker that comes with Ultimate. Maybe I'll save myself some $ by going with Pro and use TrueCrypt for volume encryption.
Why do you want to upgrade? The difference between the two is almost nil.
Because Microsoft committed fraud. The EULA for Microsoft Windows 7 Home Premium says that I can run it on 2 physical processors in one machine, but in practice it only recognizes one Intel Xeon processor in my Dell Precision T7400. Therefore, I need to upgrade to Windows 7 Professional to get the functionality I was previously promised by Microsoft in a written contract.
