It has something to do with a root file being deleted. ShelExecuteEx is a root file. My sister had to reload her computer when it did that. You might want to weight and see if anybody can tell you else wise. If not well... BOOM. I'd back-up first.
Thanks HELPHELP , just this second solved it, its the
" Application information service" i had to backtrack what i had been doing today, and i had mistakenly set this service to manual, the service had already started, but i had stopped it, and set it to manual, and basically could not do a thing.
But a few days ago, i had printed the default settings to the services in windows 7, and had kept a list of what services i changed, and noticed the mistake.
To fix this you go into safe mode, and just start the service again, and set it to manual.
