There is no straight Run command for launching System restore. The executable for this application can be found in the path C:\Windows\System32\restore\rstrui.exe. So to launch the tool from Run we can specify the executable path in the Run window. If your system drive is not C:, then the drive would vary. Or you can just run the command %systemroot%\system32\restore\rstrui.exe which would work irrespective of what your system drive is.
