Hello all,
I'm trying to upgrade UserPort (or any other parallel port unlocker) for WINDOWS 10.
UserPort is running fine under XP but one must now use WIN10.
Does anyone tried it on WIN 10?
Thanks a lot for your help

What I have tried:

I used USERPORT under XP successfully

What on earth are you talking about? What is "UserPort"?
A parallel port is never "locked", so you're going to have to explain what you're trying to do with it.

So, why have you not downloaded the source, tried building it and solving the build-errors?
It's available, you can get it and do your own work. People here will help if you put some effort in first.

UserPort was old software in 2005 - Do you really still need it?

A lot of things has changed since the old XP times - mostly in security. You will need a newer version. Maybe you got to debug the code to find the problematic pieces.

parallel port? Sounds like its time for a printer/machine upgrade. That reminds me. Time to re-load the green bar paper in my tractor feed printer.

LPT is top notch ultimate hardware and it has to be conserved for the future the most we can.

It has a wonderful thing, you set a bit in the user software side and you get a real effective voltage in the LPT physical pin, with no glue logic in the middle, nothing in the middle than can fail.

Of course many won't find that useful if their projects are only generating information, but for those that want to use a PC to move real things in the real world the LPT is still an impressive resource because its simplicity, minimalism and top notch effectiveness.

UserPort only provides the 32-bit device driver binary (the UserPort.sys file). If you want to use it in Windows 10, you'll have to recompile the device driver for 64-bit version, and have a proper Digital Signature for it. You can use a test Digital Signature for the driver, but the OS must be configured and then rebooted to allow test drivers to be loaded.

Hi all,
First, thanks for your replies.
I'm an old hardware and software programmer, and if I really mandatory need the parallel port, it's why I REALLY NEED THIS PORT. I dislike solutions such as USB FTDI chips, because USB programming is a mess compared with the straightforward simplicity of the parallel port. I don't understand why Microsoft killed the Parallel Port, and curiously even now one can always purchase motherboards with parallel port on the market ? (AsRock, Gigabyte for example)Strange ? Why Microsoft don't help customers to unlock this port ? Of course I tried TEENSY solution with the USB port, running fine, but the computing power of the Teensy, and the bandwidth of the USB link is not comparable to the 8 bits Parallel Port speed coupled with the incredible even low cost PC computing power. Moreover I'm controlling a large Pipe organ through the parallel port with an real time hardware system I designed, without extra microprocessor. You can watch it here :

Tomas Franzon kindly gave me the UserPort software, but I couldn't recompile it under W10. Some libraries are missing such as ntddk.h
But new motherboards with parallel port are only running W10. Which apart the 64 bits capability, andthe huge amount of disk it requires, brings strictly nothing compared to WINDOWS XP.
Thanks for your help !

No info what the "UserPort" does exactly here.

To write an 64Bit-Kernel-Driver for Windows is no easy task, don´t do it.

It´s time to replace Parallel-Port. Newer Cipsets/Mainboards do not have any of them. Even if you find a Parallel-Card the kerneldriver will only support devices it was build for.
To use the pallelport for "other" things you can use a USB-Parallel
development module such as:

https://www.ftdichip.com/Support/Documents/DataSheets/Modules/DS_UM245R.pdf[^]

It has driver-support for several operating-systems, even 64 Bit.

If you want professional real Hardware-Ports, you can buy an Multi-I/O Card from NI.
