    Hi, have you checked your desktop for Win 10 compatibility?
    Windows 10 Upgrade
    Windows 10 Update

    I can't find it on either of these.

    That -er- small point aside, you may have an outside chance of finding a driver using, say, Drivermax (free for 2 drivers a day).

    In device manager, for that item you are having an issue with:

    Right click, properties, then the details tab.

    Select Hardware ID's and copy all that below that appears here. I believe there may be more than one that we can search for ... worth a shot anyways ...

    Do a scan with Drivermax- pretty quick. You might be lucky- it's found me two I needed and didn't get/couldn't find for devices otherwise.

    A quick search brought up this info for me:

    Name: Intel(R) B75 Express Chipset LPC Controller - 1E49
    Device ID: PCI\VEN_8086&DEV_1E49&SUBSYS_074F1025&REV_04\3&11583659&0&F8
    Driver: C:\Windows\system32\DRIVERS\msisadrv.sys, 6.02.9200.16384 (English)

    Here is the x64:

    DriverMax search for Intel(R) B75 Express Chipset LPC Controller - 1E49 on Windows 10 - 64 bit

    Here is the x32:
