I can't find these files anywhere in this laptop.

Please Help.

    Hi MarkPacana

    That is very strange, those drivers are almost always installed into C:\Windows\System32\drivers

    Hi MarkPacana,

    If you open Device Manager, then at the top, select View - Show Hidden

    Can you find the Western Digital (WD) and the MediaTek USB device (not a MediaTek network card), if you can right click and delete them from there.

    this may / may not help, clicking around today

    Removed old device drivers = Success this afternoon.

    WD & MediaTek

    9/6/22:

    4:07 pm Device Mgr Sys.Devices -> removed oem34 (Western Digital SES)

    4:09 pm Device Mgr Sys.Devices -> removed oem16 (MediaTek CDC)

    4:12 pm Win 11 Settings -> Security : Core Isloation "ON", Restart

    4:15 pm WD 4 TB EasyStore installed, functional, Ejected WD

    4:18 pm Surface App wants to "Update" with OEM34 vers. 1.2.0.0 11/30/2017 (Deferred WD Update)

    The Microsoft Surface App warned about old device drivers, leading to "Core Isolation" 

    Why did the Microsoft Surface Application want to downgrade the Driver after removing it ? 

    The Surface App now appears on screen automatically, but not in "Startup" {surprise} 

    S

    Checked results w/the command prompt, elevated privilege, using:

    dism /online /get-drivers /format: table

    Surface Studio 2 (config @bottom)
