Handle: Handle is basically a console version of ProcessExplorer (command-line options instead of the GUI) with a bunch of additional features to release locked handles instead of killing the whole process.Despite being a less-straightforward way to get the job done, I still consider it to be a better alternative than blindly using an "Unlocker" software because it gives you a better understanding of what's actually going on. Process Explorer: you can use Process Explorer by SysInternals to see all the currently active processes within your system, including the names of their owning accounts and a full list of handles (files) that the process selected in the top window has opened: the tool doesn't have an option to directly unlock these handles, but it will allow you to identify the process which is keeping the handle locked and close (or kill) it accordingly.Unlocker: you can use Unlocker, a freeware application made by Cedrick Collomb, or IOBit Unlocker, a similar software made by IOBit (also freeware), to force Windows to release the lock on the file(s).Let's start with a brief summary of the three main techniques that could be used nowadays to unlock a locked file on Windows. In this post, after a brief recap of these techniques, we'll try to explain what a "locked file" actually is and why abruptly unlocking it might be troublesome in some common scenarios. About 4 years ago we've published an article explaining how to unlock a file handle locked by SYSTEM or any other active process in Windows using three different techniques: the post hit more than 100k visits, showing how important the topic actually is for most Windows users.
