How do I change Windows 7 starter to a regular Windows 7?
 

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