What should I do if I open the CAD prompt in win10 and send a command failure to the program?

In windows 7 windows8 windows 8.1 windows 10, double-click the dwg file, the following phenomenon may occur: pop-up error dialog box: send command failure to the program, when double-clicking multiple dwg files, multiple ACAD processes will appear in the task manager . Regarding these two issues, it has also plagued me for a long time.
The method is finally right today. In fact, you only need to close the system's LUA in the right way.
1, press the keyboard win + r key, enter regedit, press back. The system opens the Registry Editor. If win + r doesn't work, click: Start --> All Programs --> Attachments --> Run.
The location in the win10 system is: Start-->All Programs-->Windows System-->Run. In short, the ultimate goal is to open the Registry Editor;

2, after entering the Registry Editor, click: HKEY_LOCAL_MACHINE --> SOFTWARE --> Microsoft --> Windows --> CurruntVersion --> Policies -->System. Find EnableLUA on the right

3, double-click EnableLUA, and set “Value data” to 0 in the pop-up window. Then click “OK", close the Registry Editor and restart the system. Both of the above problems have been solved.

Note:
1. In the windows10 system, from the "Control Panel--> User Account--> User Account-->Change User Account Control Settings" Close LUA Does not work. Only use the method described above.
2, in the windows10 system, after closing the LUA control, the system built-in store applications, such as Edge browser, XBOX and other applications can not be used.
