Yesterday evening/night I tried to install the newly released Windows Vista Service Pack 1 Release Candidate on both my work laptop and my main computer at home. The really great parts are that Microsoft added a progress indicator, which after the second restart in an upgrade scenario now indicate at what stage the installation is. There is unfortunately bad news as well, the installation bug I told you about earlier remain. The bug is that every first installation of SP1 installation fail with the error code 0xC004F013, but the second time it always works to install. Another installation issue is that I cannot install SP1 on my main computer, where SP1 installation fail with error code 0x80070059. Let’s see what Microsoft have to say about this!
