boot up takes longer

i have installed CSC just now.

what i have found is my boot up getting longer and almost stuck.
no changes made to CSC after installation.
using all default settings.
not running any cleaning yet.
can someone explain this to me?
and one more thing i found CSC service is running in the background by looking at task manager under services tab.
but i have not checked the box to run during startup.
is that normal?
i decided to uninstall CSC.
my machine boots up as usual.
fyi, im running win7 x86.
for now i’ll stay away from CSC although it looks beautiful and got interesting features.
please clarify on this.

thanks a lot. O0
