According to some documentation I found,


  Routes added by using the -p option are stored in the registry under the following key: 
  
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip \Parameters\PersistentRoutes


Perhaps you could just use Group Policy Preferences to set the appropriate entries directly in the registry?

Adding static route through group policy
In the simple trace formula of Deligne Kazhdan one assumes that the test function is supported at the elliptic regular elements at one place and is a supercusp form at another place.  Why can't one just assume that it is supported on elliptic elements (not necessarily regular)?

More specifically, I don't see how the regularity assumption is used in the proofs of the simple trace formula.  I understand that one can get around it using Arthur's work.
