Windows Updates - Does Not Install, how can I remove it

First see if you have any applications using SQL Express, you can look in C:\ProgramFiles, find the Microsoft SQL folder, then go thru and find the data folder. Look at the dates to see if and of the DBs are current. If they are not then uninstall and install the latest version of SQL Express 2005 if you still want it. If something is using it then your best option is to try and apply the SQL Express service pack manually.
