I need to run a service interactively on my computer.
(I am already aware of the implications.)

How do I enable a service (running in session 0) to run interact with the current desktop in Windows 7?

As of Windows Vista, there are no directly interactive services. "Allow service to interact with desktop" is basically just a legacy option, although if you use it UI0Detect should pop up and allow you to switch to a special desktop to interact with the service.

This article describes some options. If you have further questions, I suggest you ask at Stack Overflow as this is a programming problem.

  • Note that as of Windows 7, the UI0Detect service is not started by default. If you need to access legacy interactive services, you may wish to change the configuration for UI0Detect to start automatically. Mar 25, 2014 at 0:48

    ...and as of Windows 10 version 1803, the Interactive Services Detection Service (ui0detect) service no longer exists: coretechnologies.com/blog/windows-services/…

As long as it is designed correctly, go under services.msc and check the box:

enter image description here

  • It says "Please enter a valid password". Also, wouldn't the privileges be pretty limited here?

  • Depends on what you are doing. . . What are you trying to do anyways? and what is the service?

  • It's a program I made for my own use. It needs system privileges, but like I said, that's a secondary worry. The primary worry is that this doesn't even work, since it's asking me for a password.

  • Services.msc is asking for a password? Select Local System account. Sorry, that SS is confusing I guess.
