This is an annoyance where a XP Sp2 machine has been upgraded to IE7 and the runonce screen gets displayed to allow you to choose your settings for IE7.
You click on apply settings but it never changes from “applying settings”
So time for a bit of registry editing.
Close your browse sessions first.
As always – editing the registry can seriously damage your machines health – so if you dont know what you are doing – GET HELP
using regedit locate
HKEY_CURRENT_USERSoftwareMicrosoftInternet ExplorerMain
if the key RunOnceHasShown is there – chase is value to 1
otherwise
right click on the right panel and add Dword value: RunOnceHasShown
then change its value to 1you may also need to add the Dword value: RunOnceComplete
and make its value 1 also
Restart IE 7 and no more run once screen
