I'd considered turning it off but there is always some odd thing that disregards default browser settings every once in a while, and very rarely will i test something in IE. By the time i would turn it off completely, i'll be entirely somewhere CCleaner cannot follow. If the hanging reaches my mild annoyance threshold, i may disengage it temporarily. I'm just a bit curious whether it is CCleaner's "fault", or something with the OS / config which mysteriously changed.

Thanks for confirming my experience. I wasn't really paying attention, but that is consistent with the behavior i had seen.

Does it hang for a bit on the IE cleaning? I don't use IE at all, but that's what it does.

Yes, the Move Large Files thing has been very disappointing. I just updated because this fuction is stated as having been optomized in this version. Yes, first thing a defrag seems to do is take items that were at the end of the drive and write them, hugely fragmented, up to the front of the drive where i would expect, say, core OS files to stay. But it seems to unnecessarily move files (and differently with every defrag) which should be perfectly happy where they were in the first place. At least i can poke things around a bit manually. Still a better defrag than many, including some fairly pricey ones. But i kind of long for somethhing like the Symantec defrag of the mid 90s.

Top of map = beginning of partition = faster part of the hard disk access. the start of any partition is closer to the center of the disk, and faster.

Is FF set to empty its cache on exit? If so, you likely will not see a large cache size when running CCleaner.

You aren't able to do this due to separation of privileges. You shouldn't be able to access other accounts from one account at all, unless it is the "real" Administrator account, which is disabled by default in Vista and 7. (Yeah, I know you can log in as "Administrator", but that isn't truly the highest-privilege admin account.)

An additional note: compacting the registry can actually be counter-productive. I've found it most useful to do on very rare occasions, and mostly with Win 9.x registries. When a lot of apps and settings have been removed, and the registry has been very thoroughly cleaned by an aggressive cleaner and by eyeballing the database by someone who knows what they are looking at, removing the "dead space" maybe helpful. But if you compact every time you clear out more or less volatile reg keys (e.g. MRU lists), guess where those keys now go when generated? Yes, way at the end of the file, in which case it is more likely to increase access times. And the folks at Piriform are unlikely to give you a setting which may decrease performance, and have to support that scenario. You really want to use a different product for this entirely, but make sure it is a good and well-respected app. There are only 2 or 3 I'd ever use, and I've tested many over the years.

OK! Ignoring already that the account is unfinished, I'm wondering what this has to do with CCleaner. Just throwing it out there: try running Explorer file manager as a separate process from the Explorer desktop.

For the time being, if you want better control over the various sqlite databases, install the SQLite Manager extension and use that. It's great if you want to delete some things and keep others.

Probably installed by someone who used your computer, if you didn't. Check the CCleaner version to see approximately when it was installed. Check Add/Remove Programs control panel to see when it was last used (unless you started the app, in which case it would show when you opened it).

Right - is the file really gone, or do you just no longer see it in the cleared Recent Documents menu? No reason that CCleaner would delete normally stored user files.

Online games? You are probably deleting cookies or other cache contents for the games. Or LSOs if they are Flash games.

If CCleaner had only been clearing a small amount of browser cache data in the past, you probably had the browser set to empty the cache on exit. No way you could even visit one page and only have 200-300 kb to clear.

If it isn't to do with Windows defender, I offer two generic solutions: Defrag the HDD. Increase the size of the MFT if it is close to full.
