Hello, every time my Windows 10 VM wants to upgrade from Windows 10 1511 to 1607 it fails with the errorcode 0x8007001f. It doesn't matter which way I choose to update, via the normal Windows Update or the tool Microsoft provides. After some searches I found out that the error basically means "ERROR_GEN_FAILURE" and "A device attached to the system is not functioning". But according to the device manager everything works fine. Any solutions for this problem?
