I have used system restore to go back to a previous working state and found my lost files, now i used system restore to go back to my previous state and just before my desktop opens a message with the tab reading "EXEPLORER.EXE" with the text "BROWSEUI.dll" was not found and asking me to reinstall it, now once i go into safe mode it also says the same message. Apart from that nothing opens up just the desktop screen with no icons, although the "Ctrl+Alt+Delete" works but not much luck, please help anyone...
