Suspend a process
It is possible to use the Suspend action in Procexp to force a process to become temporarily inactive. This frees a system resource (such as network, CPU, or disk) for other processes. The Suspend option is also useful when you need to perform diagnostics on a program or if you need to inspect what a suspected malware program is doing to your system.
To suspend a process, right-click on it and select Suspend:
There is one problem, though – if a suspended processes was running a visible application, the application window can’t be minimized, resized or moved. To resume a suspended process, right-click the process again and select the Resume item from the process context menu.
