Unfortunately we are already here to report a problem with Windows 8, in fact, many users who tried to upgrade their operating system, had the following message at the end of the installation: \"windows 8 install has failed\".

The Microsoft support says it could be a problem with the drivers and then to try again the update in a few weeks so giving to all producers to update their drivers to the new operating system.

So either wait or not confident let spend 14 days to request a refund.
