GMA is not a Win10 supported product line, though you aren't blocked from upgrading to Win10 and using a Win7/8.1 driver.
Fair warning though that because your product is not 'supported' on this OS, we advise continuing use on the OS it was designed for. For the best experience on Win10, there are a range of new Skylake based platforms already out and coming soon which are great with Win10.
