Using our boards with Windows 8

Due to Window 8’s requirement that all drivers need to be signed, some of our boards requiring USB drivers might not work with it. RadiatorTwo shared a workaround witch should work. Basically you need to turn off the signed driver requirement.

You can deactivate the forcing of signed drivers by using following Settings.

Open a Command Prompt (cmd) as Administrator and type in following two commands.

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

With bcdedit you´re configurating the bootmenu of windows, so be careful. If something goes wrong you´ll need a windows dvd to repair the bootmanager.

After a restart you can install the driver normally. You just have to confirm to install the unsigned driver, just like in older versions of Windows.

  1. Here is another method to install unsigned inf files. (This works to install infs for USB CDC)
    1. Windows Key + R
    2. Enter shutdown.exe /r /o /f /t 00
    3. Click the “OK” button
    4. System will restart to a “Choose an option” screen
    5. Select “Troubleshoot” from “Choose an option” screen
    6. Select “Advanced options” from “Troubleshoot” screen
    7. Select “Windows Startup Settings” from “Advanced options” screen
    8. Click “Restart” button
    9. System will restart to “Advanced Boot Options” screen
    10. Select “Disable Driver Signature Enforcement”
    11. Once the system starts, you can install unsigned drivers.

  2. there is a waaaaaaaaaay better course of action then to disable driver signature .. since win8 is a crappy os not worth installing made for idiots by an idiot (who btw got sacked from ms for making them believe this will not be a piece of crap made for idiots)…

    – stay on winxp/win7 if you can’t live without winblows
    – move to linux and discover real freedom

  3. AAhhhhhh, Windows 8…..Feel the “love”…..LOL Microsoft for you, taking something that barely works and making it worse/braking it/removing what little DOES work…….and juggling/hiding the rest!

  4. The really annoying part is they did this and STILL don’t have a means to install standard USB devices like CDC/audio/network devices without a driver. I need a SIGNED inf file just to let windows know that this VID/PID is a uart? Really?

    1. I can’t say linux is a perfect electronics box ’cause it isn’t (no proteus, no altium, no many other applications that one might like to use) but
      – microchip stuff works like a charm (mplab, pickit2, pickit3, hid stuff, cdc stuff …)
      – bunch of other stuff works perfectly trough wine (different compilers and tools, most eda tools work, almost all simulation tools work)
      – there is a bunch of foss native stuff (gEDA, KiCAD, 4 or 5 different spice versions etc etc)
      – native ARM tools
      – native Atmel tools
      – Arduino (if you really must use arduino)
      etc etc ..

      so it’s very usable (waaaaaaaaaay more usable then win8), but, if you reeeeeally don’t wanna move to linux, why the hack move to win8? it’s not good for sht, not that it does not work for electronics, it does not work good for nothing

  5. your all a bunch of blowhard idiots. where is your glorious os? did you contribute to linux? what gives you the right to talk so much shit about an os who’s code you couldn’t comprehend if it was printed out in front of you. self righteous elementary school educated walmart employees.

  6. I’m using vmware player to start windows xp and the driver installs there just fine. I’m using the USB infrared toy V2, record and play works using irtoy.exe from the virtual machine. I wouldn’t disable the driver signature on windows 8. I would rather wait for a signed driver for windows 8. In the meantime I can do some software test programs in windows xp. Waiting for a signed driver, Lucian
