There was no need for this malware since Win2k. Windows installer manages pretty well and 3rd party ones too. On win7 I uninstalled amd video driver, installed nvidia driver using their own intallers and stuff simply worked, without any "cleaning". Same with other big applications, e.g. MSVS, MSOffice etc. Yes, Windows (7, 8, 10) have some curious folders that tend to fill up with something, like winsxs and Installers, but you can't just delete stuff there anyway, it is needed by OS, so malware like CCleaner won't help there.
