If I upgrade to Windows 7 with Windows 7 upgrade, will all the settings on my computer be the same?

[SaulVT]

I just want to know how for sunlife Office 2007 Enterprise Serial Key tomorrow and need my laptop to run Genuine Windows 7 for their software. Currently i have Microsoft Office Pro Plus 2010 Product Key installed. I want to know if I can split my hard drive and when computer boots I can choose xp or Office 2010 Home And Student 64bit. So I can use xp for work and windows 7 for home. Since i don't have the cd for Windows 7 Professional Product Key I don't want to remove it completely. Any suggestions and help would be appreciated!
