GNU radio installation and USRP

Hello all,

I am new to GNU radio software. I have used step by step instructions
given in:

http://www.tools4sdr.com/articles/Tutorial+to+install+GNU+Radio+with+cygwin+
and+Windows_2688210

to install gnu radio with cygwin.

  1.   What basic check can I do to ensure that gnu radio has been
    

installed correctly?

  1.   Do I mandatorily need to install USRP drivers if I don't use 
    

USRP
hardware?

Thanks in advance.

Best Regards

Ravi
