Hello sir/madam, I would like to help you, please let me know when you are ready.
I checked the make and model, YES, you will be able to upgrade your sony to windows 8.1
there will be new features, like the start button.
you will not need to update your drivers
everything will work after the upgrade
are you getting any error messages?
what happens? why are you unable to upgrade?
can you go to
and press install 8.1
Let me opt out and redirect this question to other experts for remote assistance.If no expert opts in back, we can continue.Best regards.
Open Windows Update by swiping in from the right edge of the screen (or, if you're using a mouse, pointing to the lower-right corner of the screen and moving the mouse pointer up), tapping or clicking Settings, tapping or clicking Change PC settings, and then tapping or clicking Windows Update.
Tap or click Check for updates now, and then wait while Windows looks for the latest updates for your PC. If you don't have automatic installation of important updates turned on, you might need to tap or click Turn on recommended settings before you can check for updates.
If there are updates that need to be downloaded/installed, please do that before trying to upgrade to 8.1
Let me know how it goes
