Whilst General Melchett has been Vista x64 from birth, we Microsoft people were recently given early access to the final Vista Service Pack 1.
Last night, I downloaded the updater. Backed up General Melchett. Double clicked. And watched.
So, firstly a note to all. When the installer says 1. Several Reboots and 2. About an hour – both are highly correct. Please be patient.
After an hour. A restart to the login screen. Service Pack 1 is installed.
Everything is working. Networking, Remote Desktop. It is difficult to quantify any gains quickly: however the formal list of changes is worth a read.
