A while ago I got rid of the usual "It is now safe to shut down your computer" message by renaming the logos.sys file in the Windows directory and replacing it with a custom made logos.sys file from an X-Files theme site.
This worked fine until I had a system crash recently and I had to reinstall Windows Me.
Everything has been restored to its former glory except my little tweak simply will not work even though I have used the same replacement file.
I simply cannot get rid of the windows message although logic says that it should be replaced as a result of a different system file being in place.
I remember doing this some years ago but the exact details elude me now. However if you use a search engine and ask something like customise windows I'm sure you will find the answer. Sorry to be so vague.
