After attempting an (uninvited) win 10 upgrade , the installer hung up at 64% , I rebooted , did the latest bios update , rebooted again and did an F8 . Again it languishes at 45%....do these things actually work? I've been at this for 3 or 4 days now.
Thank you for contacting the Intel Communities.
I would like to recommend you to follow this guide: Windows® 10 Upgrade Instructions
Please double check the steps to be performed in "troubleshooting"
