Office 2003, Office 2007, Office 2010, and Office 2013 support Windows 10 While we recommend you use the Windows 10 Upgrade Advisor tool present in the Get Windows 10 app to check if your installed programs work on Windows 10 as well, users who are using older versions of Microsoft Office will be glad to know that one can install the decade-old Office 2003 on Windows 10 (version 1507) without any issues. Yes, Office 2003, Office 2007, Office 2010, Office 2013, and the upcoming Office 2016 are fully compatible with Windows 10. This is fantastic news for millions of PC users who are still using Office 2007 and Office 2010 for a variety of reasons. In short, if you have Office 2003, Office 2007, Office 2010, or Office 2013 on your Windows 7/Windows 8.1 PC, you can keep your Office installation while upgrading to Windows 10 (version 1507). However, note that you must have installed the latest Office service packs. It’s important to note here is that Office 2003, Office 2007, Office 2010, and Office 2013 are compatible with Windows 10 version 1507 (released in July 2015). But that does not mean that these versions of Office will be compatible with a feature version of Windows 10. You might not be able to install these versions of Office (especially Office 2003 and 2007) in a future version of Windows 10. Gabe Aul, Engineering General Manager for data and fundamentals team at Microsoft, recently shared a picture of running a 20-year-old Office for Windows 95 on Windows 10! That said, since Microsoft no longer supports those older versions of Office programs, we recommend you upgrade to a newer version of Office as early as possible.
