I've been having this problem for quite a while by now. It worked before but from certain moment all of color pallette fixes for old games stoped working. This includes the classic explorer.exe kill, registry edit by PID, dx dlls override and other utils.
I know that the quickest way to solve this would be by reinstalling the system, but I really have no time for this since I've got hundreds of programs installed and it would take several days to reinstall them all.
Any ideas what could have happened or where should I look for the source of the problem? The most probable place of the source would be the Windows registry, though I have absolutely no idea where to look.
I have Windows 7 SP1 updated up to date.
Let me know if any of the logs could be useful to post them here.
Thanks and Regards
