Why would Microsoft Leave dummy RHPROXY in NTCore based windows 10 Pro, Home, editions RRS feed

  • Question

  • HI Team@Microsoft, Experts,

    Statement from Michael XU-MSFT "The Resource Hub Proxy driver service is a kernel mode driver. It exists in windows 10 only(Home,Pro, Education, or Enterprise)"

    NT Core - > Windows 10 Pro, Home editions.

    I am trying to leverage RHPROXY based user access to I2C/SPI/UART.

    [1] First, i ensured that Microsoft windows PRO [NT Core] has RHPROXY.SYS driver in it.

    [2] Changed ACPI node and i got till devcon.exe and i find 1 device.

    [3] then later, i see that I2CTestTool.exe shows "No I2C Controllers on this system". Upon digging,i found that RHPROXY is dummy/useless on the windows NT Core [which does NOT expose User mode access to SPI/I2C/UART via RHPROXY].

    please confirm the following

    [a] NT Core -> windows 10 Home, Pro OS editions

    [b] i see windows 10 Pro, Home has RHPROXY file in driver. but it is dummy/useless

    [c] so in NT Core based windows 10 Pro, Home Operating systems, the RHPROXY is just dummy if present [since I2CTestTool.exe returns back NULL]

    question: -  Why would MSFT confuse by having RHPROXY in Windows 10 Pro, Home edition, when it is dummy [since I2CTestTool fails]? or am i misunderstanding it. Please help on how to move on with I2CTestTool.exe returning NULL.
