Your model appears to have no Windows 8 support. Go to this website. If you follow the process, you will get this message. The VAIO model you selected does not support the Windows 8 upgrade. If you want continued 'full' use from your computer, revert back to Windows 7. You need to do a back to factory reset. Note that unless you save all important stuff, it will be lost after the reset.
(Your computer has been supplied with a recovery partition in place of disks.) This is how the recovery partition is accessed. For Sony VAIO, restart and press 'F8' or 'F10' repeatedly until the 'Advanced Boot Options' screen appears. You may have to try more than once to get any of the above to work. If after repeated attempts, you have no luck or the machine reports that there is no recovery partition, your only option is to contact the computer manufacturer and ask for recovery disks for the model. After the reset, you should get all updates from Windows Update EXCEPT for hardware devices.
