Updater 3.1a
-updatebatch now will (or at least should): *Download new batch and name it [updater]*.bat *Open that script in a new CMD window. *Exit The [updated]*.bat script should: *Copy itself overwriting the original batch (without renaming). *Start that script in a new CMD instance. *Exit. The new script, with the original name, should: *Delete the [updated]*.bat script *Begin the normal script routine. @earthing do you think I should still rename the scripts to .old or something before overwriting/deleting?
