Just in case anyone else runs into this problem, I seemed to have found something that works other than turning off Windows Desktop Manager. I found a link to this post buried in one of the MicroSoft Answers threads here's the link to the post with the fix:

http://www.mydigitallife.info/fix-windows-7-screen-flashes-to-desktop-with-not-responding-error/comment-page-1/#comment-902397

Here's what it says:


Windows 7 may occasionally display a symptom where the screen flashes after user optimizes the computer shutdown speed. The symptom happens whenever user selects a folder or browses to new web page, the desktop which supposed to be in the background will jump or bring to front – flash out for a while, and the “Not Responding” error message will display on the top left corner.

The problem is probably due to optimisation to increase PC shutdown speed and decrease time required to shut down the computer. The change can be used by Windows optimization utility or technical user who modifies the registry manually. When the setting is changed, Windows 7 may encounter lack of buffer time or other slowness.

To fix the screen flashing issue, follow steps below.
Run Registry Editor, and then delete the following registry keys


HKEY_USERS\.DEFAULT\Control Panel\Desktop\HungAppTimeOut
HKEY_USERS\.DEFAULT\Control Panel\Desktop\WaitToKillAppTimeOut
HKEY_CURRENT_USER\Control Panel\Desktop\HungAppTimeOut
HKEY_CURRENT_USER\Control Panel\Desktop\WaitToKillAppTimeOut
HKEY_CURRENT_USER\Control Panel\Desktop\WaitToKillServiceTimeOut

Restart the computer after deletion, and the screen flashing issue on Windows 7 should be fixed.[

Further down the page someone added a bit more:

This solution worked for me too – after days and days of looking at other resources. I did not find HKEY_USERS.DEFAULTControl PanelDesktopHungAppTimeOut or HKEY_USERS.DEFAULTControl PanelDesktopWaitToKillAppTimeOut but I did find the other two under HKEY_CURRENT_USERControl PanelDesktop. The last one I found in two places under HKEY_LOCAL_MACHINESYSTEMControlSet001Control and ControlSet002Control – I had to run a search to find them.

*** Note: the first time I tried this I didn't search the registry properly. You need to search on the last part of those lines to find the registry entries. Eg. search on "HungAppTimeOut" not "HKEY_USERS\.DEFAULT\Control Panel\Desktop\HungAppTimeOut". Might seem obvious to most people but I've not touched REGEDIT very much.

Also check that you have the right part of the registry tree before you delete anything. Repeat the searches for the other strings and you should find them all.

So far so good, no flashing windows and no "not responding" messages.

Thanks to everyone who helped. My IT department wouldn't which was why I came here. So thanks again.
i made an account just to thank you for this suggestion i've done what you said on windows 10 and its fixed the exact same issue i was experiencing. been hunting for a fix for almost 3 days solid and came across this as one of the only fixes that worked. any game i would play in window mode would continually flash white like a snapshot was being taken similar to an android phone does screenshots and this was done every half second or so. also if i'd alt tab out of a full-screen game the game would stay minimized and not allow you to alt tab or click back in.

i know its rude to bump old an old thread on any board. but the only alternative fix i found would be a fresh os install and i thought if someone was going through the same issue as i have they would appreciate a lil more info in the right direction
