No newer Drivers available in WindowsUpdate, on Fujitsu-Website or on Intel-Website. Devices failed to load with „Code 10“. <\/p>\n
System works fine, but no sound available. And: System Startup-Time when doing a fresh restart of the system increased significantly (Machine seems to stuck for about 1-2 Minutes at the Boot-Screen still showing the Fujitsu-UEFI-Logo and the loading Windows-Progress „circle“), but when waiting with patience the Machine boots and then runs at normal speed.<\/p>\n
Eventlog<\/h2>\n
System Eventlog Source MEIx64<\/em> shows several entries with:
\n„Intel(R) Management Engine Interface driver has failed to perform handshake with the Firmware (FWSTS0: 0x90000245, FWSTS1: 0x89118306).“<\/em>
\nas well as „The Intel(R) Management Engine Interface is being disabled<\/em>.“<\/p>\nSolution (Workaround)<\/h2>\n
After a while I figured out that this problem is caused by the setting „Disable new DMA devices when this computer is locked“. This setting was introduced with v1703 and I enabled it some month ago to protect my BitLocker-Key from DMA-Attacks (see this Blog-Post<\/a>).<\/p>\n
When updating to Windows 10 v1709 this setting leads to my described problem.<\/p>\n
Countermeasure (Workaround): GroupPolicy Editor (gpedit.msc)
\nComputer -> Administrative Templates -> Windows Components -> BitLocker Drive Encryption -> Disable new DMA devices when this computer is locked. <\/em><\/p>\n![\"BitLocker](\"https:\/\/hitco.at\/blog\/wp-content\/uploads\/BitLocker-DMA-Policy2.png\")
BitLocker DMA Policy (Disabled)<\/figcaption><\/figure>\n Set this to „Disabled“ => reboot the Machine => Problem is solved, both the Sound and the Intel ME Interface are working again.<\/p>\n

Device Manager, System-Devices<\/figcaption><\/figure>\n Seems we have to wait for a Patch until this Setting can be reactivated again!<\/p>\n
