What is "Run" dialog box?
The "Run" dialog box can be opened by press <Win+R>, it looks like this:

Run Box
What is it used for?
It is used to start a program by typing its executable file's "full path", if you're used to launching the programs by typing instead of clicking on the icons, it will be a small but practical tool. In fact, not only to start programs, but also to access folders, documents, and even web pages. But we only use it to access the commonly used programs without path and extension, for other things, it is slower than use File Explorer or clicking icons.

Note: why on above screenshot I have not input "full path" for "mspaint", just executable filename without extension? Because there is a system environment variable names "PATH", it contains the paths of almost commonly used programs, and if you ignore the path, the "Run" box will search the typed program under these paths. For extension, if you have not inputted, "Run" will presume it is the executable file, such as *.exe, *.bat, etc.

Tip: once you started a program in "Run" successfully, it will remember the typed text, this feature will enable you to input fewer characters next time. E.g. type "m" the list will show the programs that start with "m", then I press <↑> key twice, <Enter>, Paint app will run.
