When the Win7 computer opens the file and prompts "Windows cannot open this file", what should I do?

When I recently used the Win7 system computer, I suddenly found a file that could not be opened. Double-clicking this file prompts “Windows cannot open this file”, how can we solve this problem? In the case of confirming that there is no poisoning, we enter the registry editor to solve this problem.

Solution:

1. First click “Start-Run”, enter “regedit” in the open dialog box to enter the registry editor;

2, then in the left side of the registry, expand to the "HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/policies/system";

3, then the right mouse button in the right side of the window click select & ldquo; new & rdquo; & rarr; DWORD value & ldquo ;, and named & rdquo; Nointernetopenwith & ldquo ;;

4, double-click the new & rdquo; Nointernetopenwith & ldquo; key, in the open & rdquo ; edit DWORD value & ldquo; dialog & rdquo; numeric data & ldquo; the original item 1 to 0 or other than 0 can;

5, then close the exit completion determination modify The registry, and then open the file of unknown format will not prompt Windows can not open this file, but will go directly to the open mode dialog box, select the appropriate program to open the file.

The above is the solution when you open the file in Win7 system, "Windows can not open this file", if the user is using other systems, then you can follow the similar operation above.
