@Andavari & @hazelnut, I only ever download CCleaner from piriform.com and NEVER from filehippo. I ALWAYS back up the registry. Kudos to Piriform programmers because CCleaner has ALWAYS worked PERFECTLY on my desktop machines, never once given me any more grey hairs than I have already ... it has only ever crashed my laptop (twice) which is why I said what I said at the very beginning of this unfortunate conversation. If it had done it only once, perhaps it could have been me who caused the error, but since it happened twice, perhaps it was the PC itself (nothing is impossible with HP computers) and the possibility of the existence of some malware in the NTFS that wasn't cleared properly. I don't know. I am not that technical despite my 30 years experience with computers. Thanks for your feedback. I am now closing this discussion.

Yes, of course, yes! Sorry - apologies - withdrawn, Your Honor! No offense meant. It's age-related dementia, I am afraid. Maybe when you get to 86 you will also have the same symptoms.

The only "evidence" I have is that it was the most recent program to be installed on the machine. I am NOT blaming CCleaner, in case anyone gets the WRONG idea and jumps to ERRONEOUS conclusions!!

No, I cannot tell you what I did to "MAKE" it happen! I ran the program as usual having used it since very early versions. I will try it again now since I have updated to the latest edition. Thanks for your response.

Hi. I did not receive any notice that any previous post had been replied to. Perhaps I forgot to enable notifications. I did save a backup of the registry. The hard disk is partitioned into 3 drives with "Drive C" as an alias on the HP factory installed OS. I cannot tell what happened. No, I did plain ordinary cleaning using the default settings. It worked fine until I restarted the machine, then a CHKDSK showed nothing but garbled characters, the check did not finish, and every reboot thereafter failed. The only recourse I had was to reformat the drive.

Hi. Since 2.30 crashed my laptop completely destorying all the data and having to reformat and reinstall everything, I have been very wary of using this software. What can I do to ensure that CCleaner does NOT trash any of my 5 systems? I am very careful with selections that may affect the OSes (2 laptops with Vista Business 32, one desktop with Vista Ultimate 64, one desktop with XP-Home and one desktop with Windows 2000 SP4). Thank you.

Eish! 2.30 totally destroyed my laptop recently. I have been using this utility for a few years without any problems, then upgraded to 2.30 and wham! Laptop needed reformatting. Now I am too scared to use this utility at all, on any of my 5 machines all with different operating systems - Win2k SP4, XP-Home, Vista Business 32 x 2, and Vista Ultimate 64. Is there anything I should NOT check?

I am incensed. Shortly after installing CCleaner 2.30 earlier this morning, the computer crashed. I had to rebuild it from the backup DVDs that I made when I bought the machine. This is the 3rd time that CCleaner has crashed my laptop. Obviously CCleaner is incompatible with Vista Business 32 on an HP Compaq 6720s laptop. Thanks. :MAD
