The easiest way to upgrade to Windows 10 Anniversary is to bypass windows updates altogether, and run the special utility provided by MS on the Windows 10 update history page. That will give you essentially a fresh installation of v.1607. Next, install the latest October 11, 2016—KB3194798 Cumulative Update to bring the OS to Build 14393.321. Direct link to the msu can be obtained from Microsoft Update Catalog, or the tenforums website. Finally, run Disk Cleanup to remove the Windows.old folder left behind. Best regards,
After the update any problem about drivers or something?
