Windows 7 flickering problem (solution)

Sollution:
1. create a text file
2. rename it .reg instead of .txt
3. add this text into it



REGEDIT4
[HKEY_CURRENT_USER\Control Panel\Desktop]
"WaitToKillAppTimeout"="5000"
"HungAppTimeout"="5000"

[HKEY_LOCAL_MACHINE\SYSTEM\Cur­rentControlSet\Control]
"WaitToKillServiceTimeout"="5000"

[HKEY_USERS\.DEFAULT\Control Panel\Desktop]
"WaitToKillAppTimeout"="5000"
"HungAppTimeout"="5000"




4. run your new file
5. restart PC
------------------------------------------
Under Windows 7:
Flickering windows, unclosable windows, moving taskbar buttons, unusable taskbar buttons, loosing window focus...

Videocard drivers are updated, the flickering problem is present on PCI-express video-card (GF9800GT), and onboard video-card (GF7) too. Also on a laptop.

The flickering appears only after installing some programs, but it does not appear constantly using the same install kits of certain software.

By disabling the "slide open combo boxes" at visual effects the flickering can be reduced a little bit.

Also another thing to avoid the flickering is to install only 1 program at a time, do nothing till then, and restart after every installation.

Should teach me to play with fire. I tried to tweak by reducing these settings to 0, can't believe it was the reason for that issue.

by the way, it seems only the "waiting time to kill non responding app" was causing this issue. I had to set it back to 5 seconds and the flickering stopped. I don't know which part of the reg file above points at that settings though.

Thanks a lot for this video.

@RokkumanEkkusu1 I'm no pro in this stuff, but I like to play with them, just make sure you have another windows installed on the pc (just in case something happens) and than you can play. Or run it in VirtualPC,VirtualBox, or VMware, that is more easy.

There are 3 entries of "WaitToKillAppTimeout" for different "users", but if you have only 1 administrator account on the pc, than is the same for all those 3 entries.

By reducing it to zero (0) Windows shuts down faster, it is ok on XP,Vista!

Thank you so much.... You've offered me a great service by posting this... Thank you for keeping me away from a nervous breakdown!!! :)

@WebReports :) ...the idea of "Waittokillapp" and "menushowdelay" registry tweaks was given by "Xylber". I played with those things in the past, so I made the registry file to add some normal values to those, and it works.

Thanks~ my computer screen stops flickering!!! But it seems that my computer takes more time for switching on.............Do you know why??

[furulevi]

@jacklo1996 More time to switch on?!? I don't know, all the timeouts refer to shutdown, not startup things... you can try to use different values instead of 5000 (5 seconds), and see if there is any positive difference.
