Yes, but how many of those XP users actually care about having CCleaner updates ? For most people, if it works, they don't mind having no updates. (Besides, the W3C's statistics are based on the W3Schools' log files. Linux does not have 4.8% of market share, and Vista has more than 10%.)

I don't think a lot of people would be hurt by dropping XP support. Using a 9-years-old OS and complaining about not having modern software is quite ridiculous.

Uh...it's not supposed to slow down the computer at all. You might be infected.

Most index.dat files are deleted after a reboot =)

Yes, but I doubt Piriform want to maintain two different builds of CCleaner with two different GUIs. I think they should fix all the little known bugs in v2, and then drop XP support for v3 while keeping the v2 download link for XP users.

It seems this is due to Internet Explorer's Protected mode. Since IE's tabs are run with a low integrity level, they can't modify files with a medium or high integrity level. Thus, IE creates this folder so that IE plugins can write where they want. When they ask for a file, the one in the Virtualized folder will be shown instead. As you have guessed, this is a consequence of UAC, since it is required for IE's Protected Mode to fully work. Those files can be deleted, but the "Yahoo! Companion" (a toolbar, maybe ?) 's preferences might be lost. However, you should uninstall that Yahoo thing unless you really need it, as IE add-ons are known to slow it down.

Exclude C:\System Volume Information\ . To do so, you'll have to enable system files/folders view in Windows Explorer's Folder Options, and then navigate to C:\System Volume Information\ after clicking "Add" in Defraggler's Exclude list:)

Yes, it does. The Paint.NET dev, Rick Brewster, once said a not-so-well-known company would offer him 80 cents per download if he bundled their "bonus software" (a.k.a. spyware) with it. CCleaner recently hit the 500,000,000 downloads milestone. Even if Piriform gets, say, five cents per download, and 20% of those downloads are the Slim build, they'd earn...20 million dollars.

Actually, nearly all Windows processes have their corresponding viruses

FileHippo isn't the only source of money. The Yahoo Toolbar is.

Again...using the Windows Classic theme is not a good idea, as Aero is GPU-powered. In fact, with that Dell Latitude, I'd bet using Classic theme would decrease performance. (that was already the case with Luna on XP. I've once enabled Luna on a small netbook...which resulted in a performance increase !)

As I said, the bottleneck is your disk. Unless you're using a SSD. The actual time spent on telling Windows it should delete files must be extremely low compared to the disk writes. Besides, not everything can benefit from multiple cores...

1) How do you know CCleaner doesn't ? 2) The main bottleneck is your disk. It's awfully slow when compared to your CPU, RAM, et al.

Clean desktop, again. I hope you'll understand the pun

As Nergal said. The whole point of the Yahoo toolbar is to get money. Nobody actually wants to install it.

Exactly. Only clean when you actually need it.

The "Don't use a beautiful background" one is ridiculous. This has no impact on performance at all.

Well, SSDs have limited reads and writes, so using CCleaner everyday will "kill" the SSD faster.

-64-bit support is already planned (I don't remember where, but MrG said that it'd come with CCleaner 3 somewhere in the CCleaner section) -The old INI files should be replaced with XML files. Much easier to edit and read (both by humans and software) -WFS as a tool (or, better, remove it) -If I say "Drop XP Support, and create an Aero-based GUI", will you guys kill me ?

That wouldn't be CCleaner. They'd have to completely rewrite the program, and as Saintj pointed out knowing where is what can be very difficult since there are lots of smartphones, even new ones *cough* Dell's Aero *cough* , running on old Android versions. Besides, they wouldn't be able to bundle anything with it, and thus wouldn't earn any money.

IE has had extensions for a very long time: http://www.ieaddons.com/ However, I doubt this is the final UI. Too Longhorn-ish navigation buttons, no space for toolbars at all (no toolbars would be a great thing, but I doubt MS would do that), a very old Bing image... I think that was either a mockup or an early build of the UI.

View menu >> Options.

Registry cleaning should not be done automatically - period. I know I sound rude, but a false positive by any Registry cleaning tool can have very, very bad consequences.

-It doesn't matter. -I don't know how Eraser works, but I assume it must be doing the same thing : filling the blank spaces with zeroes. -No, unless you have *very* sensitive data. Wiping the entire drive because a dozen of files must be securely deleted is rather pointless. -It returns it. -Same thing. "Secure deletion" means "fill the file's content with zeroes". -I don't know. But anyway, they can't be recovered. -You don't need to, but the answer to this question is yes. However, don't forget two things : -Secure Deletion with more than one pass is pointless, unless you use very old (>15 years) drives. -Wipe Free Space is useful only if you mistakenly deleted a file instead of securely deleting it. However, unless that file is really important, you shouldn't have to worry about that.

Use df.exe and its command-line parameters
