Just adding to the good advice already given to you......
Since you do not specify which version of MS Office 2010, I just want to add this info for you in case you are not aware of it :
excerpt : Home and Student
Although the Home and Student version of Office 2007 and Office 2010 don’t contain Outlook, note that the license conditions are quite different for this version. For instance, with this version you are allowed to use the software on 3 machines within a single household as long as the main users of those machines are also a member of that household.
