I understand this. My question was, is there any difference between using an uninstaller program and using the regular uninstaller followed by a cleanup program like CCleaner? IOW, would CCleaner/etc cleaning up the pieces left behind accomplish the same exact thing as an uninstaller program, making such programs nothing more than a redundancy and merely a way to perform the two functions as one?The official uninstaller basically only removes the entry from Installed apps and basic files and that is it.
3rd party uninstaller tries to remove everything related to it (config, logs), some leftovers might cause issues.
Zemana, even portable version, leaves 2 services running, imagine, what it might cause, if you install other AV.
Since Revo Free does have x64 support I guess I'll add it to the considerations, though I have a nagging feeling there was another reason I wasn't considering it.
