We want to change the status of an order without going thru the process of Shipping and Invoicing. There are instances that Magento will lock the status of an order to pending until the order finishes its shipment.
This hack will activate all the order status on all states. What I mean is the Status dropdown in the Comment History, by choosing the desired status and Submitting the Comment. We can change the status of the order to Complete or Closed or any available status for that matter.
All we have to …

By default, Magento doesn’t allow you to delete Orders on the backend.  Well, there is no option in the admin for now.  But guess what? there is a work around (yeah~ I know you’ve already expected this.).  Boutik Circus created this “Delete Orders” extension which allows you to delete cancelled orders.
Why can we delete cancel order only?
That’s because deleting a complete order breaks links with invoices and shipments and could creates a lot of troubles.
Go to Delete Orders Extension.
Install this extension via Magento Connect Manager.
Magento Connect -> Magento Connect Manager

Hey Guys,
This is Kaspersky Internet Security 7. This version has a license until 2011, if Kaspersky doesn’t catch it by then. I tested this out, the patch doesn’t contain any virus. Download it here. Read the Kaspersky.txt for the procedure on how to activate your Kaspersky Internet Security.
If you already have a Kapsersky installed in your system. You will have to uninstall it first. If add/remove program files won’t work. I have a kaspersky remover here.
