Official : Amazon confirms Vista SP1 out tomorrow

Online e-tailer Amazon has confirmed that Vista SP1 will be out tomorrow in the US as it lists pre-packaged Windows Vista Home Premium with SP1 upgrade available as from the 19th of March 2008, citing a release date as early as tomorrow.

Amazon.co.uk lists Vista SP1 upgraded products as being available from the 4th of April 2008 which is not particularly surprising since shrink-wrapped products usually lag behind their web-only equivalents; existing UK Windows Vista users will still be able to download and install it as soon as Microsoft's servers release it.

Computer Manufacturers like Dell or HP should start selling SP1 equipped computers and laptops as soon as Microsoft gives them the green light, which should happen within the next few hours.
