What should I do if the response speed is particularly slow when the Win7 system opens some software?

What should I do if the response speed is particularly slow when the Win7 system opens some software?

1. First open the win7 start menu and open the “Run” option, then enter the “regedit” command to press the OK or Enter key; you can also use the key combination “Win+R” ; shortcut to open the run window;

2, open the registry editor, then in the list on the left, expand to "HKEY_CURRENT_USERControl PanelDesktop";;

3, then in the right window Right click on the blank, select “New”,“DWORD 32-bit value" (PS: Note key-value type), and rename it to “WaitToKillAppTimeout” (PS: Some guard software has this function Some users may already have this key value, so there is no need to create a new one, just follow the operation), and at the same time, change the value of the key value to 0, click “&” and then “OK” to close the registry editor.
