Hello Dennis, I went though the links. I didn't found specifs for CCleaner and logged a problem to Microsoft. As I can see there is a lot of issues with Vista SP1 so I am not surprised of the problem I got. I will just stop to use the application and afraid to use Deffraggler which is an other tool that does a good defragmentation of the disk.

Hello Jamin4u, I am using CCleaner since a long time now and always satisfied. Recently I have updated my Vista Enterprise to Service Pack 1. I then downloaded the last version of CCleaner v2.23.999 and run it out of the box like I usually do. I unfortunately got the same problem as brac37. My system is now corrupted and the last known successfull boot doesn't work anymore. I am getting a cyclic BSD followed by a reboot. Only the safe mode works. It looks like the registry has been corrupted, maybe wipedout. Is it a bug of this version of CCleaner or is it something releated to Vista SP1? I am using also Deffragler since a long time but I am afraid to get the same issue again... Do you have clues ?
