How to Use Resource Monitor to Find Which Process Has Locked a File
Many experienced users use the Process Explorer utility from SysInternals to obtain extended information about the processes and applications running on the system. This is actually a great utility, but in Windows a new handy tool called Resource Monitor has been added, with it you can get extended information about running processes, associated descriptors and libraries (for example, dll files). Resource Monitor can be used as a tool for researching processes and determining file locks, which can be especially useful in cases when you have forgotten your combat toolkit at home, but you need to figure it out now.
- To start Resource Monitor, click the Start button, type resmon.exe and press enter.

In the search field, you can also enter the name or path to any registry key, as a result of which the Resource Monitor displays a list of all processes that use the specified registry key / branch.
