Some User have complained about the Run Command missing from Start Menu due to some virus effects. Also users when press ( Windows Key + R ) to use Run command an error message appears
This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
Run not displaying in Start Menu
So I have finally came up with the solution for it. I have made up two solutions, Manual and Automatic. First try Manual and if it did not work then try Automatic.
Manual Solution
Open My Computer –> C drive –> Windows –> System32 –> Locate gpedit.msc file and run it. See the figure below
While you have opened Group Policy see in the left pane and in the User Configuration Expand Administrative Templates and select Start Menu and Taskbar now in the right pane locate Remove Run Menu from Start Menu and double click it. See the figures
Select Disabled in the properties dialogue and press apply then OK
Now close all open Windows you will see the Run has been restored in Start Menu. See the figure now
