Win7 program does not respond to time reduction method

There are more and more people using win7 system, win7 compatibility is much better than vista, but running some old programs under win7 will still appear that the program is not responding Of course, even under XP, this situation will still occur. The difference is that the XP processing time is relatively short in response to the program, and the win7 processing program does not have a long response time. How to shorten the win7 program response time? Please see below:

Run the registry, expand to HKEY_CURRENT_USER\\Control Panel\\Desktop, and then right click in the blank space on the right side to create a new "DWORD 32-bit value".

Double-click the newly created value and rename it to "WaitToKillAppTimeout".

After renaming, you don't need to modify the system defaults, save the changes and exit.

The above registry modification can shorten the system response time of Windows 7, and avoid the problem of system suspended animation and other issues. In fact, "WaitToKillAppTimeout" exists by default in Windows Vista, but I don't know why Microsoft canceled it in Windows 7.
