Without having a tool to dump the updates installed, I would have to say all updates except stuff like NetWare drivers updates, any Genuine Advantage updates, and Media player new releases. It is running IE6 SP1 (can't go higher that that for what I do). When I looked for the actual error on the Internet (see attached screen snap msvcrt-dll..png), it basically said that some program replaced msvcrt.dll with one that was missing the entry point "_resetstkoflw", and to find a good copy of msvcrt.dll with "_resetstkoflw" included, and update Windows with that.
