Q: I use Microsoft Office 2007, which I load from a disk instead of my hard drive. After a recent Windows 10 update, most of the icons for my Word documents changed from a blue "W" to an orange "MS."
When I click on those icons, a message tells me that I don't have Office on my PC, then offers to let me try or buy Office 2013.
I checked on Office 2007, and learned that, while it will continue to work, there will be no more security updates for it.
What can I do?

A: The way you load Office 2007 is probably the cause. The larger question is whether you should continue to use that program.
Try installing Office 2007 on your hard disk instead of loading it from another disk. That way, Windows 10 will be able to verify that you have a copy of Office, and will allow your Word files to be opened by it.
But should you keep using Office 2007 now that it no longer receives security updates? It depends on your appetite for risk.
If you continue to use Office 2007, you might be the victim of a malware attack in the future (you can read about past malware attacks on Office at tinyurl.com/ycbnbzyr and tinyurl.com/yd2o82e8). But it's not a clear-cut case of "replace or else."
A recent survey showed that many businesses continue to use Office 2007, despite the risk (see tinyurl.com/yaaaroac).
