Level: Recommended For Experts Only

Description:
The dos and 16-bit programs run on windows 2000 in the virtual dos machine program. It provides 16-bit environment with dlls also. 16-bit programs run as threads in a single and shared vdm process by default. They share the memory space allocated to the vdm process and therefore, they cannot run simultaneously. If this tweak is enabled, then the checkbox for run in separate memory space appears on the run dialog box. It gives users the option of running a 16-bit program in its own dedicated ntvdm process. The additional check box is enabled only when a user enters a 16-bit program in the run dialog box. For this, go to start > run menu, enter regedit and navigate to the registry path listed below. You can create a dword value memcheckboxinrundlg in the right panel, if this value does not exist. Now, right-click and modify its value to 1 to show the option. However, if you want to show the original state, change the value data to 0 or delete the added value. The changes take effect after a restart or logoff. When editing the registry it is highly recommended to run a quick scan for optimization, you can test your system now for free.
