I'm stuck with a pesky file named 'ISODrv64.sys' that just won't delete. It's only 150KB and came with an application called UltraISO, which I've uninstalled ages ago. Whenever I try to delete it the normal way, I get a message saying it can't be done because the file is open in another app. I've checked Task Manager but couldn't find anything using it. When I try the 'del' command in the command prompt, I get 'Access Denied', and even tools like Unlocker and File Locksmith haven't helped. I've also tried using Process Explorer but I'm still at a loss. Can anyone help me get rid of this file?

You could try following some helpful tutorials on finding out which process is holding the file open. Here are a couple of links: [How to Find What is Holding a File Open](https://www.youtube.com/watch?v=kPyrEMNK2xc) and [How to Find What Program is Using a File](https://www.youtube.com/watch?v=KeVkJykOlUY). They might give you some good ideas on how to tackle this.
This file might be loaded by a service that’s running in the background. Check your running services to see if anything stands out. Disabling the service might free up the file so you can delete it.
I went through the services but couldn’t find anything unusual.
