Here is the tool called "Vista Update Integrator" beta 3. I tested it with x86 32 bit all five major verson to integrate Service Pack 1. Takes some time but integrate flawlessly. It made with dot net framework. I do not have 64 bit system. Please somebody test it on 64 bit system. Interface is like "vLite" Enjoy. Post comment about this.
