Hi,
I truly think, that SQL Serve is one of the best databases on the market.
But back to your problem. Most of the problems regarding the installation of SQL Server service packs or updates seems to be, that the sql-server services are set to "manual" or "disabled".
When the installation tries to restart this services, it fails, because it does not change the start-up settings of these services.
Please remember, that this is only a tip - not a solution.

I think that this forum is the better place for your questions about SQL Serrver.
