"... 'tee-object' is not recognized..."

You mean the tee-object cmdlet doesn't work? This works for me:

PS C:\Dokumente und Einstellungen\karl\Desktop\monks> perl -e 'print q
+q(Hello world\n)' | tee-object -filepath shyamasoni-out.txt
Hello world
PS C:\Dokumente und Einstellungen\karl\Desktop\monks> cat shyamasoni-o
+ut.txt
Hello world
[download]

Could you copy & paste the exact error you get from PS (activate Quick-Edit mode, mark region in PS with mouse, press ENTER and then CRTL-V...)?

Update: See also Set-ExecutionPolicy Cmdlet.
