Why it takes to long to add command line for registry cleaning ?

As a system administrator cleaner is an amazing tool to clean your windows system and with command lines, I just automate the cleaning, the only issue is to clean registry to you have to do it manually...For how long should we wait for such feature to be added to CCleaner.

The one word that comes to mind is: Safety

While CCleaner's registry cleaner is seen by many as being less aggressive that doesn't however mean that it can't have a false positive and suggest removing registry data that can break something and the breakage may not be obvious for days, weeks, or months.

So thing means "Never" ?

So thing means "Never" ?
Never say never, but yeah never

Fair enough, And one thing if you may know the answer if I start CCleaner in "/AUTO" it closes (process closed) and relaunches itself into the notification area, it is meant to be like this or another security measure and how to avoid it if possible.

Thank for your time really!

Restarting itself sounds like Monitoring may be enabled. Here's some info on it if you wish to disable it:
