Find out which process is locking a DLL without extra tools

Today I got the "The process cannot access the file ... because it is being used by another process" error again, during a development build. And as long as the DLL is locked, it's not possible to do a successful build.

Most sites and tips on the internet suggest to download some tool to detect which process is using the DLL. It seems that not many people are aware that

, since Windows XP, we don't need to download (or even pay for) a tool to detect this.

Just launch the windows console and navigate to the directory of the DLL. Now type

tasklist.exe /m /FI "MODULES eq locked.dll
and it will show you exactly which processes have loaded and locked this DLL. For moere information about tasklist use
tasklist /?

I wish you nice day
