Vista - System restore process takes a long time

When I restore system with this tool I wait arounf hour or two hours when
this process finished. And I don't know how long time this process might be
in process.
On XP I disn't remember that I was watching such trouble. On Vista only.

"Please wait while your Windows files and settings are being restored
System Restore is initializing..." and it message I watch very much time"
In left of this message is a little clump. animation. the animation of clump
is working. So I think, tha the my computer has',t hanged. system is working
in that time. But SR service fault or have simular problem

I can only press power or reset button in that moment because I think that
this process have fault.

Yeahh. Exuse me. I don't know English. This "speech" was staying from
school. Where I studyed it.

If somebody can't understand me I try rewrite this text.

Thanks

will test Erunt (http://www.larshederer.homepage.t-online.de/erunt/). I think
I won't solve this trouble. Very little number of people have this problem.

I'll test to unmount all disks except first disk. to clean and install system
on this disk.
After it will to mount another disks and test all again.

Thanks that You're helping me. ...to take that I know English very worst
