babyshiori writes "Users of Microsoft Windows Vista can rejoice in the fact that Microsoft just released a preview of the Windows Vista Service Pack 1 Release Candidate! The build is the lead-up to the actual service pack, which will be made available to even more testers at a later date. 'In our early tests with the beta, we saw some small improvements in boot time on an HP Compaq 8710p Core 2 Duo notebook. Before SP1, the laptop took 1 minute, 51 seconds to boot. After the update, that figure dropped by almost 20 seconds. Microsoft is also touting improvements in "the speed of copying and extracting files," so we tested a few of those scenarios. We noted a slight increase in the time required to copy 562 JPEG images totaling 1.9GB from an SD Card to the hard drive of the aforementioned HP Compaq notebook.'"
