I was in a rush to shut down my laptop so while windows was shutting down i held the power button for 5 secs to shut it down faster (I know, I'm so stupid!). But now programs that were still active at time of shutdown refuse to work. Some of these are office 2010 starter & Windows Installer cry. Is there a fix for this?
You should always close all programs before restarting or shutting down your pc. Sleep is the only mode where it is fine to leave your programs running.
You are going to need to do a repair on the programs in question, or uninstall and reinstall them.
