It is surprising how many 90s tools remain popular today: WinZip, WinRar, WinAmp, CCleaner, Icq, Real Player, etc. People just get into using something and simply never stop. Then there's the comfort barrier to switching (e.g. I know how to use WinZip but 7Zip is new and unfamiliar). CCleaner is still popular with low level tech support types, which is quite ironic as it damages the Windows Registry on later versions…
Can you point me to a description of CCleaner's problems? It's still my go-to tool for cleaning computers, and I've never had a problem or heard of anything major (besides the normal bugs that get fixed). It also isn't a 90s tool, being first released in 2003. What's your idea of a better alternative?
CCleaner's registry cleaner is the main issue (aside from the fact it makes computers literally slower by clearing every single cache it can find). Some of the issues it has caused:
- Registry damage: Windows 8 store was damaged/corrupted by a previous version (you had to run DISM to repair it), Windows uninstaller corruption (this impacted Mcafee anti-virus around 2009, the uninstaller would become unusable), deletes preferences for unconnected devices (USB sticks, external drives, network drives, etc) so if you have any software installed externally the drive letter may shift and the software will break, deletes unmounted but valid COM objects, and so on...

Everyone is saying the same thing. Registry Cleaning is unnecessary, won't improve performance, and really only offers you a chance of doing damage. Registry cleaning hasn't been important since XP, and XP shipped over ten years ago.
Everyone else CCleaner does is either stupid (clearing caches) or duplicated of internal functionality (IE cache clearing, Recycling Bin emptying, etc). Plus Disk Cleanup isn't a new addition to Windows.
