This is a good idea if you want to save both desktop and hard drive space.

To remove the Recycle bin from your desktop, go to Start > Run and type gpedit.msc

Go to User Configuration > Administrative templates > Desktop > Remove Recycle bin icon from desktop

Enable it and reboot or type gpupdate.exe into the run box to apply changes.

If you want to completely remove the Recycle Bin, go to Start > Run and type regedit.

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Explorer\BitBucket/C and open NukeOnDelete. Change the value to “1″ and reboot.Job done
