Setting Enable System Monitoring Has Lock Symbol

What is up with the lock symbol??.

I thought system monitoring was free?. :unsure: Although I can tick the box. Will it work?.

Could someone please explain this. Thank.

OK. Thanks. So in other words I just tick the enable system monitoring box. But it still doesn' t explain the the pro lock symbol underneath that. Thanks.

Here is the documentation for monitoring functions using CCleaner Professional Version

Are you using the portable version

Sorry folks. But I migrated to [removed competing product name]. Works how it should. No hassle. Thanks though for the non answers.
