Windows7 system program response time has a coup

Windows7 system program response time is long:
First step, enter “regedit” in the start menu search box, and then press Enter to open the registry editor.
The second step, expand the registry key "HKEY_CURRENT_USERControl PanelDesktop", right-click in the blank space on the right side of the window, and create a new "DWord 32-bit value".
The third step is to rename the newly created value to “WaitToKillAppTimeout”, the system default value data is ““0”; no need to modify, directly save and modify and exit.
Under Windows7 system, the program response time is too long. It may be that multiple programs run at the same time, which slows down the running speed of the system. Users can shorten the response time of the program by operating according to the three small steps described above. Reduced waiting.
