Best uninstaller ? does it exist ?

[Jeremy]

Useless? Far from. While the speed gain might be barely noticed, most cleaners do far more than just cleaning. They also fix all kind of errors and such.

I am well aware. I have been using CCleaner for years. Cleaner, Registry, Uninstall, and Start-Up.

Again, depending on what you use, you will not necessarily have a use for CCleaner.

I have a friend in Taiwan who only uses portable applications. I introduced to him the other day to Sandboxie. I run my web browser and any new applications in Sandboxie. Nothing is written to the host OS. It's completely isolated. When you're done, you empty it and it is as if you had done nothing. Hence, no need to take action with CCleaner.
