It is a common sight now a days when one of the viruses have disabled our various Windows services like Task Manager and Run but here is a list of 2 free Replacement tools of Run (Windows key + R) which can be executed in place of the Run dialog.
1. The name of the tool is none other than Run itself and needs no installation. Just download it and execute it to run the commands in it.
This is a great tool to run the commands just like the Windows default run dialog.
Note: Using these tools at places like schools or colleges, where these are blocked intentionally, can be risky.
