hello, I'm new here, but I've been using CCleaner for some years now(before ver2.0) and i really love it...
well, my suggestion is basically to add a little "tab"(like the cleaner, registry, tools tabs) for driver cleaning, which would clean driver leftovers as programs like driver sweeper or driver cleaner do.
this would be really helpful because to install drivers the right way, you're supposed to uninstall the original driver, reset, run a driver cleaner in safe mode, reset again and install the original driver.
well, i hope i explained myself right(my english can be kinda crappy, my original language is spanish)
I just don't find that suitable for inexperienced users as curiosity with that might cause harm to them if ever they mess up with the drivers using CCleaner.
