Back to the desktop, ie, the most obvious, when switching tabs, the screen always flashes, even the IE icon on the taskbar will disappear instantly and appear again. What is the matter?

Solution for over-optimizing Windows 7 splash screen
>

This method is only valid for over-optimized Windows 7 splash screen!

Note: Please back up the registry before using it!

If you use Optimizer to optimize Windows 7 shutdown speed, then Unfortunately, your screen will flash, that is, when you click the folder, the desktop as the background will jump out and flash, and not responding will appear in the upper left corner.

Solution:

Delete HUNGAPPTIMEOUT and WAITTOKILLAPPTIMEOUT subkeys under HKEY_USERS\\.DEFAULT\\DESKTOP

Delete HKEY_CURRENT_USER, HKEY_CURRENT_USER\\Control Panel, HKEY_CURRENT_USER\\Control Panel\\Desktop HUNGAPPTIMEOUT, WAITTOKILLAPPTIMEOUT, WAITTOKILLSERVICETIMEOUT subkeys.

After rebooting, Windows 7 should not flash again.

Looking at the registry key and found that there is HungAppTimeout under HKEY_CURRENT_USER\\Control Panel\\Desktop, but I am surprised that I have not used the tossing software like the optimization master. After deleting this item and restarting, the problem is solved. (Because the screen flash is sometimes not easy to observe, attach an identification method that is unintentionally discovered, insert a u disk, click the icon in the lower right corner to safely delete the hardware, and see if the pop-up box is in the normal position or the top of the screen. The top word indicates that there is a screen flash problem.)

Installing the pp accelerator leads to a solution for the windows7 splash screen:

Uninstall the pp accelerator and delete the HungAppTimeout item in the registry.

Or, if you must use the pp accelerator, add a logout script and delete the HungAppTimeout registry entry each time you log out.

The following is the content of the reference:

Dim OperationRegistry

Set OperationRegistry=WScript.CreateObject(“WScript.Shell”)

OperationRegistry.RegDelete(  HKEY_CURRENT_USER\\Control Panel\\Desktop\\HungAppTimeout”)

This piece of code is saved as a vbs file, added to the group policy (enter gpedit.msc in the run to enter the group policy) - user configuration - windows settings - Script (login/logout) - Logout, so HungAppTimeout will be deleted each time you shut down or restart. It is also a rather helpless solution.

In fact, it is understood that there is a WIN7 splash screen solution on the Internet, this is a tool used to solve windows7 flashing when playing games, such as Fantasy Westward Journey, Dahua Westward Journey and so on. Flash window. Run this gadget, WIN7 will not flash, is it simpler?
