Hm, this is bad. Vista creates big problems with some programming tools and databases. I will not use it for my daily work. It is waste of time. And all these popups even when you only want to copy some files will also waste my time.

But maybe it is possible to install Vista on a second partition additionally to XP. But I heard that there are some problems to make a dual-boot system with XP and Vista.

Edit: Thanks for the Reichelt-Link!
