On my desk top all went fine with Service pack 1 install
however on my lap top it crashed out on the restart and I had to
remove the service pack 1 install to make it work again.
(had to use advance settings and system restore)
My desk top is a clean windows 7 install But my lap top was
a vista upgrade to windows 7 so I wiped the lap top and started
again with just Windows 7 install. and then loaded service pack 1
and it worked without any problems at all. chatten
So beware if you have an upgrade version as this might cause problems scrtg
