What am I seeing?
When using Windows 7*, the Unknown Devices in Device Manager can show multiple errors.
Details on the device show ACPI\MSFT0101.
How to fix it.
|Intel® NUC Model||Solution|
|D34010WYB, D34010WYK |
This error occurs when you enable the Intel® Platform Trust Technology option on the Security tab in BIOS.
Windows 7 doesn't support this setting, so it can be disabled in the BIOS.
Windows 8.1* and Windows® 10 do support this setting.
|NUC5i5MYHE, NUC5i5MYBE |
To fix the Unknown Device error, download and install the Windows 7 and Windows Server 2008 R2* Service Pack 1.
If the error still occurs after installing Service Pack 1, install the Hotfix from KB2920188.
The above update(s) clears the error in Device Manager. If the included TPM needs to be used, the operating system must be updated to Windows 8* or later.
