Change readme restoring old drivers section #290

Hey, your uninstall process might fail on windows 10, as there is an additional step involved to get the proper windows drivers for certain devices. Your app seems to sign and add a device driver certificate, which windows will believe is the better driver for the device than it's own. To undo this step:

  1. in device manager, click update driver image
  2. browse my computer for drivers image
  3. let me pick from list of available drivers on my computer image
  4. Here, DC-S5 (my camera which I tried to change the drivers of) has now a new driver signuature. This needs to get removed, but I don't know exactly how. The proper driver is MTP USB Device, which makes my device work again. image This fixed my device. Thanks for your tool <3 cheers,

Yes I always use this method myself.

I want to add another piece of information on that topic:

Drivers generated by Zadig (driver provider libwdi when checking the drivers properties) for one driver type (lets say WinUSB) and one device (for example 303A 1001 00 and 303A 1001 02 which are respectively the CDC serial interface and JTAG interface in the ESP32S3 microcontroller I'm working with) can co-exist instead of being replaced each time. This creates layers of libwdi drivers that will ALL be prefered by Windows 10 instead of the default one, as stated above.

This means that performing the uninstall process (Device Manager > Uninstall device > Delete the driver software for this device) will only remove ONE layer of driver, letting another driver of the stack be used in turn. So from the user perspective, performing the uninstall procedure currently in the FAQ can look like nothing happened, or have hard to understand effect like seemingly restoring a different driver that you thought had been replaced. If like me you have tried many different things in desperation while trying to make yous device work, the layers can be >6 deep.

Performing the steps above can work, as at step 3 you will see all the drivers next to each other, and at the bottom of the list the original one from Mricrosoft.

Performing the current uninstall procedure multiple times might be safe as Windows won't suggest "Delete the driver software for this device" when you have reached the bottom (removed all Zadig and other installed drivers for that device). Though dont take me at my word, I have NOT analyzed the full ramifications of doing this yet (it fixed my problem for one device but I cannot attest that it will be the right solution overall, nor that it won't break other things !
