If you want to enable the option “Add Run In Separate memory space in the Run Window” in Windows 8, check this out
Normally we use either a 32-bit program or a 64-bit program in Windows. 16-bit applications are backward today. But still there are some 16-bit programs needed to be run. Or you may want to run some old games which you like the most. Windows Virtual DOS Machine (VDM) program simulates a 16-bit environment to run any Dos or 16-bit programs. Here a shared memory space is given for all the Dos and 16-bit programs. But the problem with it is that, because of the shared memory, we can switch between those applications but they cannot run simultaneously. If you need to run them simultaneously, then you need to run those in separate memory space. For that you need an option in the Run window and that is: “Run In Separate memory space”. This tutorial will show the way of adding this option. All you have to do is to follow the instructions carefully.
1. Open the Run window by pressing Windows + R key simultaneously. Now type “gpedit.msc” without quotes in the text area and hit Enter.
2. Now the Local Group Policy Editor window will appear. Navigate to User Configuration -> Administrative Templates -> Start Menu and Taskbar.
There you will find “Add Run In Separate memory space in the Run Window” on the right pane of the window. Double click on it or hit Enter after selecting that option to open.
3. By default this Not Configured option is checked. Check Enabled and click on OK to apply the change.
Now you are done. From now on, when you open the Run window, you will see an extra option:
“Run In Separate memory space”. You can see it below.
Remember, until you type name of any 16-bit program to run, this option will stay disabled and thus it’s colour will be gray.
