Computer prompts "Cannot verify publisher Windows has blocked this software" what to do

The specific actions are as follows:

1, in the WIN10 system we just open "Cortana" and then search "regedit" found after we have to press "enter" on it.

2, okay, and then we go back in and we just need to locate:

Hkey_current_user\software\microsoft\windows\currentversion\policies\associations

Note that if you do not have the last "association" item, right-click on policies, select New → item, and then rename to associations

3, in the right margin to right-click, select new → string value, named Lowriskfiletypes

4, then we double-click Lowriskfiletypes, and then copy the following number into the can:

. zip;. rar;. NFO;. txt;. EXE;. BAT;. VBS;. com;. cmd;. reg;. MSI;. htm;. html;. GIF;. BMP;. JPG;. Avi;. mpg;. MPEG;. mov;. mp3;. m3u;. Wav

Reboot the system at this time, the modification can take effect. If this problem occurs later, we can refer to the 4th step above to deal with, but the operation should be noted.
