I am on windows xpsp3, and had used "Hotfix uninstallers" cleaning feature before. Recently I did some system update, then used the new CCleaner, but the "Hotfix uninstallers" option is gone. I reverted to version 5.46 and found the option again. And after done the cleaning with ccleaner 5.46, I found that there are still those directories under \windows: $968930Uinstall_KB968930$ (strange name, with only two files in it: PSCustomSetupUtil.exe, PSSetupNativeUtils.exe) $NtUninstallMSCompPackV1$ $NtUninstallWdf01009$ $NtUninstallwinusb0200$ $NtUninstallWMFDist11$ $NtUninstallwmp11$ $NtUninstallWudf01000$ $NtUninstallWudf01009$ $NtUninstallXPSEPSCLP$ I wonder whether they belong to "Hotfix uninstallers" or not.

I am not a perfectionist on this. It happens that Defraggler find some highly fragmented files that I don't need, so a quick delete is enough. I won't scroll down to check if those less fragmented files should be deleted too.

My objective is not quite the same. I use Sandboxie or any virtualization software when I try something suspicious, or something concerning security. I use CCleaner to get free space by system cleaning. I use Defragger to promote hard disk performance. My original suggestion is for fragmented files found by Defragger, which need cleaning instead of defraging, and cannot covered by CCleaner. Virtualization is indeed another story.

A little off topic... The files left over by imcomplete uninstallation is just an example. I have encountered other files that originated by normal computer operation. Anyway, your thorough recommendation list is appreciated. Did you compare those with Sandboxie?

Restore is kind of over-treatment in the case; if I try something really suspicious, I run Sandboxie. I do use Windows system restore, only for worst system crash cases.

Thanks for your suggestion. Yes, files that being created regularly could be added to CCleaner, but those random, temporary files that cannot be anticipated, just be awared of when seen, as in Defraggler, is what I am talking about. Uninstaller cannot cover all these files either. "Open containing folder" is a good command, yet most of times I just want a quick delete.

I know what these files are only when I see them. For example a file left behind by an uninstalled software.

I know; I am referring to those non-specific files

CCleaner do not recognize all the crap; some are just as temporary as you said.

No need to bind your hands so tightly; and if so, why should it ask whether to dump recycle bin at start?

When viewing the file list after analysing, sometimes I found a fragmented file is not needed, and should rather be deleted than defragged. But there's no "delete highlighted" option. Hope it could be added.

I am terribly sorry: They do have been cleared. I forgot to refresh the result. Sorry for the noise.

I thought so too, but No, which is odd

Please add an option to clean the MRUs, like under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU, thanks!

Yes, it can restore. I have restored to a previous restore point. But I want to reserve another older restore point.

Thank you all, I think the suggestion to turn system restore on and off will surely works and I'm going to do that. Yet still I wonder whether the correct restore point sequence could be recognized. If it can, then it will be a good enhancement of CCleaner.

Yes, one of my restore points are incorrectly dated, due to once wrong system time setting. I wonder whether the correct create sequence can be recognized, and delete that specific restore point. It is not the most "recent" restore point, although it has a future time stamp, and CCleaner greyed it out.

I don't know if my understanding of restore points is correct: the restore points are linked like a chain according to the sequence of snapshot, not the time of snapshot. But CCleaner seems sort them by date, and don't let me delete a previous restore point which created at wrong (future) system clock, now always recognized as the most recent. Could it be solved?
