The discovery of the consequences of Windows Vista’s so-called “Multimedia Class Scheduling Service” (MMCSS) is one of today’s big topics in all the computer news gazettes. I just verified the problem myself, and what can I say? It’s true! :)

Not even three months after the Beta 2 version, Microsoft released the first Release Candidate of its forthcoming Windows Vista operating system to the public. My Beta 2 test lasted only one week, because Vista simply wasn’t ready for everyday use back then. But according to numerous other reviews on the net, RC1 made much progress since. I was a bit sceptical about that – how far could they have come in just twelve weeks? So it was time to do another test with the current public pre-release version. The bottom line this time: Vista has indeed become a somewhat usable system. I’m not going to ditch XP in favour of Vista soon (simply because I’ve already installed too much applications on the »old« system), but in a year or so, I think that will be an option.

Normally I don’t like trends like this, but I’m into eye candy and wanted to see if the Vista Desktop really proves to be usable on my normal desktop system. And I had that 32GB empty NTFS partition on my hard drive that really needed to be filled :)
