Microsoft Windows 10 free upgrade revisited: seven of your questions answered

More than 200 million people are already using Windows 10, but will your old software and peripherals still work if you accept this recommended upgrade?

I upgraded from Windows 7 to 10 and it looked like everything went fine, even though it changed my home screen saver and where the icons were listed. The one thing I cannot get to work is our HP OfficeJet 7310 All-in-One device, which functions as a printer, copier, scanner, and fax machine. Now the printer function is the only one that works.

New operating systems usually require new drivers, and for full functionality, this usually means drivers provided by the manufacturer. If these aren't available, Microsoft will install generic drivers. Perhaps that's what's happened here, by mistake.
