Is your laptop 32-bit or 64-bit? I presume you have stopped all virus protectection and similar type software.
With that...have you COMPLETELY uninstalled ITCH (try Iobit's uninstaller with advance removal - free) then re-install ITCH.
You will find that more resources are needed (compared with Mac) when using windows. Your specifics, should remedy that, however.
Hope this helps.
Note: I still use ITCH 1.7.1...as I am running a Mac Mini with only 1gb ram...If I use a newer update, system tends to glitch (memory issue -- soon to be fixed).
Just for kicks, try reverting to it (most stable version before change-up to 2.0+), if you are still having issues... (I am using NS7).
