Shrink Volume
After installing Windows Vista on my new Lenovo, Windows claimed the whole disk space for itself. Maybe I missed the option to adjust it during the installation process.
Anyway, Vista provides a tool to shrink a hard disk partition. Using this tool I was able to downsize the partition to 145GB but not more. After some investigation I found out, that many unmovable files (system information) where written at the end of this 145GB. With only about 20GB on a 145GB volume it was no possible to reduce it more.
Fortunately I found help on the Internet. I will not explain the whole process here again, because I think they did a pretty good job on How-To Geek. I have to add only one thing: I did not delete the c:\pagefile.sys.
On this How-To Geek site there are several programs mentioned. The one I used was PerfectDisk2008. An absolutly brilliant tool! The only down is that it is not free… but with this tool I could have downsized my partition to 21GB 
Now I am working happily with an 80GB partition.

Guido! you cannot promote chargeable software
“Lenovo. Windows” -> “Lenovo, Windows”
“space” -> “disk space”
“a lot” -> “a lot of” (probably better: some or many)
