 QCSuper can run on Windows, but you should beforehand ensure that Google's ADB prompt correctly runs on your machine with your device, and you should as well manually create `libusb-win32` filters (through the utility accessible in the Start Menu after installing it) in the case where your device directly needs to connect to the Diag port over pseudo-serial USB. (Please note that if you mode-switch your device, the associated USB PID/VID may change and it may require to redo driver associations in the `libusb-win32` filter creation utility - and/or in the Windows peripherial devices managers depending on the case)
 
-On Windows, you may need (in addition to Google's ADB kernel drivers) to download and install your phone's USB drivers from your phone model. Please search for your phone's model + "USB driver" or "ADB driver" on Google for instructions.

 Then, you need to ensure that you can reach your device using `adb`. You can find a tutorial on how to download and setup `adb` [here](https://www.xda-developers.com/install-adb-windows-macos-linux/). The `adb.exe shell` (or whatever executable path you use, a copy of the ADB executable is present in the `src/inputs/external/adb` folder of QCSuper) command must display a prompt to continue.

 Still in your command prompt, move to the directory containing QCSuper using the `cd` command. You can then execute commands (which should start with `py qcsuper.py` or `py3 qcsuper.py` if you installed Python 3 from the online installer, or `python3.exe .\qcsuper.py` if you installed it from the Windows Store).

+As noted above, it is possible that you have to add a `libusb-win32` filter through the utility available in the Start Menu in order to ensure that the interface corresponding to the Diag port is visible by QCSuper on the mode-switched device (a first failed attempt to run the tool using the `--adb` flag should trigger a mode-switch if the ADB driver is working and the device is correctly rooted).
