Yesterday I managed to download the Windows Vista SP1 RTM from some ***** place and tried it right after downloading in my PC. I did a clean install of Vista in a new partition and installed SP1 on it. Before trying it out from there, I slipstreamed it with Vista RTM DVD and used Windows Automated Installation Kit to create the .wim file for the DVD. Now what I have is a fully functional SP1 integrated disk and later I also installed SP1 directly from the media.

Nowadays I am trying SP1 with a great enthuasisam and checking the so called reliability and performance factors behind it. Though using it just for a day does not justify a quick decision made solely upon it, I am moreover satified what it is offering. The boot up and shutdown times are greatly improved and already decreased upto 25% in comparison with the previous build. AERO is great to use now and is tear free everywhere. The system resource usage is reasonably cut down and thus improving system performances. I am extensively checking the other parts of the OS to find out the differences.
