If you bought a new Windows 7 PC, there's a good chance that it has Office Starter 2010 pre-installed on your hard drive. This software suite from Microsoft contains stripped down versions of Word and Excel that are supported by ad banners.
If you want to continue to use Office Starter 2010 when you upgrade your Windows 7 PC to Windows 8, Microsoft has now set up a support page specifically to address this situation.
Basically, Microsoft says you have to have the latest version of Office Starter 2010 installed before updating that PC from Windows 7 to Windows 8. Microsoft states:
If you don't install the latest version of Microsoft Office Starter 2010 on your Windows 7 PC before upgrading to Windows 8, you won't be able to use it after the operating system upgrade is complete.
The required update is available on Microsoft's website.
Earlier this year, it was reported that Microsoft will discontinue Office Starter 2010 later this year. In its place, Microsoft will reportedly tell its many OEM hardware partners to use Office Web Apps as the replacement for Office Starter 2010. These are the web based versions of Word, Excel, PowerPoint and OneNote.
