Windows Server 2008 R2: No Remote Desktop Access after SP1 Upgrade

When I updated my Windows 2008 R2 Servers to SP1 via Remote Desktop I lost my RDP session when the machines reboot (which is normal).

Sharepoint 2010: How to remove “Edit in Sharepoint Designer”

In Sharepoint Foundation 2010, there are menu items and ribbon buttons that allow you to edit things in Sharepoint Designer.
