My friend got a new Windows 8.1 laptop. I am helping her cleanup things that came "free" from HP (games, etc).

In the list of programs installed, I see "Microsoft SQL Server 2005 Compact Edition" and 9 versions of "Microsoft Visual C++ Redistributable" (ranging from 2005 to 2010).

She is no developer and never installed those. What are they doing here? Is it safe to uninstall?
