I’ve a dell 8300 laptop with windows 7 operating system, whenever I turn on my laptop I get this message “preparing to configure”, “Configuring Windows features - 35% complete”, “Failure configuring Windows features. Reverting changes”, then it goes to welcome screen and start normally. This process take 10 to 15 minutes and it happen every time when I turn on or restart my laptop. Please tell me what should I do to fix this problem. Please provide me a solution to resolve this problem. Please help me. Your any advice will be appreciated.
