Hi, can anyone please tell me how I can find out what application created a DefaultAppPool user account and associated folder (c:\users\DefaultAppPool) on my Windows 7 Pro machine. It has suddenly appeared as if from nowhere. Many thanks Ian

Hi Alex, thanks for the reply. I figured it was related to IIS myself. What I can't figure is why it appeared from nowhere. I have never configured or used IIS. I didn't even know what it was until I saw the DefaultAppPool folder and started digging about. So, I am trying to figure out what application my have configured or be using IIS, I certainly wasn't me. Appreciate any guidance. Ian

Hi, For this issue, you could check the task manager to see if there are any process related to IIS. meanwhile, if this issue occurred recently, you could check the software you isntalled lately.
